Alloy-clad Wear Plate Product


Trimay ® Wear Plate Ltd. manufactures overlay/inlay onto steel plate for corrosive, erosive and abrasive environments. Our company began in the United Kingdom in the 1950s, at a time when chromium and tungsten weld overlaying was a relatively new concept. Since then, Trimay® has progressively improved its processes, and has developed stronger bonding and higher-grade wear plates using a proprietary SAW manufacturing process. The benefits of SAW stem from the fact that the flux covers the reaction, shielding it from contaminents, resulting in a smooth surface with little-to-no porosity. Today, Trimay's operations are headquartered in Edmonton, Alberta, Canada.



Overly Types


Boron

Borocarbide Overlay

Released in 2010, T171 borocarbide-based overlay is the newest addition to Trimay's product line. It is developed by Trimay Wearplate Ltd. using NanoSteel® Technology under license from The NanoSteel® Company, Inc. It is the second best cladding we offer. It is lighter and more affordable than tungsten alternatives, plus it has outperformed tungsten in turbulent slurry,own-hole drilling application. We recommend checking if Trimay's new borocarbide suits your application before purchasing CCO, complex or tungsten alternatives, but be careful!... if improperly applied, it will outlast its purpose!



T171

T171 Plate and Pipe

T171 is a patented iron based steel overlay with a near nanoscale (submicron) microstructure was developed by Trimay® Wearplate Ltd. using NanoSteel® Technology. It is the closest-performing alloy we have to tungsten. Despite its high hardness (68 - 71 HRc), it has good impact resistance. This is due to the refined complex borocarbide phases which are surrounded by ductile ferrite phases. The borocarbide phases are completely wetted by the matrix and prevent premature pull-out, delamination and crack nucleation. Their refined nature allows the reduction of stress concentration sites and the ductile matrix supplies effective crack blunting and bridging, resulting in the improved impact resistance.

Chromium

Chromium Overlays

Chrome cladding are the most widely used and are well rounded wear deterents capable of absorbing some impact. Our company offers 3 grades that operate best in moderate-to-heavy wear environments with mild-to-moderate impact tolerance. These are Trimay's most common alloy cladding formulas, and have only been slightly modified since the beginning of the company. They have been tried, tested and proven repeatedly.

T138

T138

T138 is a iron-based steel overlay wear plate solution with a unique proprietary chemical composition designed to withstand moderate direct impact and a mild-to-moderate wear environments. This alloy typically 'as-welded' contains 24% chromium carbide and is well suited for tough jobs that demand more protection than any other steel offers. When applied, it boasts a lower coefficient of friction, the same hardness (HRc), and better abrasion and corrosion resistance than annealed steels.





Common Application

It is economical to use T138 for areas exposed to moderate wear and impact that can benefit from its low coefficient of friction. It is often used as a liner coating for shovels, buckets, draglines and heavy haulers to prevent carryback and extend the life of the accessory. Contact us for the technical data sheet (TDS) including the typical as-welded chemistry of this alloy.



T156

T156 - Plate Only

T156 is an iron-based steel overlay wear solution with a unique proprietary chemical composition designed for moderate wear environments with moderate impact. T156 is similar to Trimay's T138 with its smooth surface and chemical make-up; however, extra Chromium and Molybdenum makes T156 more resistant to wear than the T138.





Common Application

T156 use is similar to T138's, but as the wear environment becomes more abrasive, so does the need to upgrade to T156. For example, it is cost effective for a haul truck moving clay to use T138 overlay since preventing carryback (the buildup of material in the box) and protecting against moderate impact (during loading) are the primary concerns; yet, the truck hauling silica sand, rock chips from mine blasting, or raw bitchumen from oilsands, needs a tougher overlay (like T156) to combat the increased abrasion from the jagged materials.

T157

T157 - Plate and Pipe

T157 is an iron-based steel overlay wear solution with a unique proprietary chemical composition designed to withstand heavy wear environments that may be exposed to mild-moderate direct impact. This alloy typically (as-welded) contains 30% chromium carbides and is regarded as the top performing chrome-based alloy on the market. It has a smooth surface, like the T138 and T156, plus extra Chromium and Manganese gives T157 up to 30% more wear resistance than T156.





Common Application

It is the best wearing chromium carbide overlay offered and it performs best in heavy wear environments exposed to mild-moderate direct impact. T157 wears longer than Trimay's other chrome overlays (T138 and T156) and, in some cases, it is more practical than using complex or tungsten-based claddings (such as Trimay's T161 or T170) which sometimes overperform and outlast their purpose. T157-clad plate is often used for coal handling and conveying applications. As a pipe inlay, T157 is a good choice for hydrotransport of abrasive and corrosive slurries - so much so, that multiple Albertan oilsand companies have added Trimay to their 'prefferred vendors' lists. Contact us for the technical data sheet (TDS) including the typical as-welded chemistry of this alloy.




Complex(multiple active carbides)

Complex Carbide Overlays

As the name suggests, there are multiple active wear-deterring ingredients in complex carbide claddings that form a 'complex' protective matrix. The 'recipe' (so to speak) is mostly chromium carbides (typically 22% as-welded) with added tungsten, molybdenum, niobium, and vanadium enhancement. Since the introduction of a new borocarbide alloy (T171) in 2010, developed by Trimay Wearplate Ltd. using NanoSteel®Technology under license from The NanoSteel® Company, Inc., complex carbide usage has been on the decline; however, there are some extremely hot and heavy impact situations where T161, T161i or T165 are the best alternative.



T161

T161 Plate Only

T161 is an iron-based steel overlay wear solution with a unique alloy composition designed to resist heavy wear under extreme temperature (between 450 C & 650 C). It is used to prevent corrosion and deter erosion and abrasion even in extreme heat.



.

Common Application

T161 is primarily used for hot and corrosive wear environments in the oil and gas, cement and power generating industries. As previously stated, our new borocarbide alloy T171 (released in 2010), developed by Trimay Wearplate Ltd. using NanoSteel® Technology under license from The NanoSteel® Company, Inc., performs better against erosive and abrasive wear than T161. T161 is generally only used where T171 is not an option. Contact us for the technical data sheet (TDS) including the typical as-welded chemistry of this alloy.



T161I

T161I Plate Only

Perhaps of all the complex overlays our company still offers, T161i's future is brightest. It is has a similar chemistry to T161, with added nickel for increased impact resistance. As previously stated, our new borocarbide alloy T171 (released in 2010), developed by Trimay Wearplate Ltd. using NanoSteel® Technology under license from The NanoSteel® Company, Inc., performs better against erosive and abrasive wear than T161i.





Common Application

Due to the nickel padding in the matrix, T161i's impact resistance is second only to Trimay's tungsten option. T161i is used as a primary and secondary crusher wall liner and in applications as a lighter substitute for tungsten-based T170. Contact us for the technical data sheet (TDS) including the typical as-welded chemistry of this alloy.



T165

T165 Plate Only

T165 is a complex/hybrid overlay wear plate solution that ranks second to only T170 in impact resistance. The active wear resisting carbides in the T165 matrix are Chromium and Tungsten (typically more than 20% 'as-welded' of each).





Common Application

T165 is often applied as a lighter alternative to T170 which is a tungsten overlay. T165 should be applied to areas exposed to frequent direct impact and intense wear such as vibrating screens. As previously stated, our new borocarbide alloy T171 (released in 2010), developed by Trimay Wearplate Ltd. using NanoSteel® Technology under license from The NanoSteel® Company, Inc., deters erosion and dry abrasion better than T165, and is generally only used in weight-sensitive areas where more impact resistance than T161i is required. Contact us for the technical data sheet (TDS) including the typical as-welded chemistry of this alloy.




Tungsten

Tungsten Carbide Overlay

Trimay® manufactures tungsten carbide claddings with wear resistance that nearly doubles the next closest alloy offered. It is heavy, it is expensive, but it is proven. Where all else fails, turn to tungsten... people make wedding rings out of the stuff for a reason!



T170

T170 Plate and Pipe

T170 is Trimay's only 'true' tungsten overlay that is not considered complex. With a typical composition of 50% tungsten, it is at the top of Trimay's product list. It is a nickel-based steel overlay wear solution with a unique proprietary alloy composition designed to withstand heavy impact and severe wear environments. T170 is unrivalled in impact resistance (due to its high nickel chemsitry) and, except in some turbulent slurry environments whereT171 testing has excelled, wear resistance as well. We recommend only single layer cladding of T170, unless custom ordered with less than 50% tungsten content.



.

Common Application

It is used in intense wear environments where other products fail, or in critical areas that must remain operational to avoid downtime. When used, it is always economical; however, in some cases the lighter, more-affordable T171 (released in 2010), developed by Trimay Wearplate Ltd. using NanoSteel® Technology under license from The NanoSteel® Company, Inc., is a viable option. Contact us for the technical data sheet (TDS) including the typical as-welded chemistry of this alloy.






Wear Ability

 

Trimay uses the ability of plate to guard against wear to benchmark overall product quality. Most commonly, the ASTM G65 test is used to guage wear ability in dry environments and, likewise, the G75 for wet (slurry environments). That being said, there are 3 guiding truths about the quality of our wear plate:


  • All overlays are cost effective.
  • Our chromium carbide entry level product (T138) consistently outlasts abrasion resistant (AR) plate products by 6 times in dry environments, and 8 times in wet environments. There are some extreme circumstances where AR plate must be used to absorb the direct impact from an environment, however, the majority of the time it is cost-effective to substitute Trimay's plate for AR.
  • Improper plate selection can (and has) resulted in our product outlasting its purpose.




  • Installation

     

    Installation of wear plates usually involves no extra work other than the 'capping' of installation welds, bolts or joints with an alloy that matches the plate overlay ordered. Weldability is limited to the substrate material, thus, depending on fabricated dimension and shape and accessibility, we often recommend installation welds directly to the back of the wear face. If the plate is double sided (D/S plate), installation via bolting or studding is common. All exposed steel should be protected using a hardfacing alloy similar to the manufactured weld overlay... click here to see Trimay's consumable/overlay compatibility chart
