Our Advantages
-
Superior Strength-to-Weight Ratio – Delivers roughly twice the yield strength of A572 50, ideal for lighter yet stronger structures
-
Excellent Weldability – Compatible with standard procedures and preheat recommendations for 2½″+ plates
-
Good Machinability – CNC and carbide tooling accommodate typical CPU requirements
-
Hardness & Toughness – Quenched and tempered structure resists abrasion and impact
-
Broad Grade & Size Options – Eight grades in cuts up to 8″ thick, 10′ wide, and 40′ long
Core Applications
-
Cranes & Heavy Equipment – Booms, frames, truck beds
-
Mining & Material Handling – Bucket liners, chutes, scraper blades
-
Bridge & Structural Fabrication – High-strength girders, gussets
-
Industrial Manufacturing – Tooling plates, work-holding fixtures requiring impact resistance
-
Military & Defense – Blast shields, structural components, armored sections
Grades & Common Use cases
-
Grade B: Standard high-strength option up to 1¼″ thick
-
Grade E/Q: Thick-plate grades (up to 6″ and 8″) with enhanced alloy content for deep hardening
-
Grade S/H/F: Designed for intermediate thicknesses with balanced weldability and toughness
