Product and Application

TruWEAR AR600 plate provides excellent properties in abrasion resistance, hardness and toughness. This quenched and tempered product excels in downstream fabrication processes like laser cutting and plasma cutting, and has limited bending capability. This product is used widely in mining, concrete, aggregate and various other industries where ultra high hard steel is required.

Available in thicknesses up to 0.500”, widths up to 60” and lengths up to 144”.

Mechanical Properties

Fabrication, Bending, Post-Delivery Heating and Welding


Material is formable based on application and conditions. Please inquire.

Post-Delivery Heating TruWEAR AR600 plate achieves its properties through quenching and tempering processes. Heating in fabrication (such as post-weld stress relieving) or in service must not exceed 300° F without risk of lowering the strength and hardness of the material.
Welding TruWEAR AR600 plate can be welded by conventional processes such as SMAW, SAW and GMAW, provided that the weld procedures used are suitable for this grade and design of the welded structure, using low hydrogen conditions.

*These statements are general guidelines. CMC Impact Metals is not responsible for the results of any welding work performed.

Standard Delivery Conditions

Surface Finish

Shot blasting and rust preventative applications are available. Please inquire.

Test Reports Supplied with shipment for each production lot in the shipment. Reports include product description, heat number, chemical analysis and Brinell hardness value.
