Heavy Steel Alloys

High-performance alloy steels designed for extreme loads, high strength, impact resistance, and demanding structural applications.

Extreme Performance Steels

Heavy Steel Alloys

Heavy steel alloys typically refer to high-strength, high-toughness, and high-performance alloy steels used in construction machinery, mining, heavy shafts, gears, and pressure vessels. These are usually quenched & tempered (Q&T) or through-hardened alloy steels with additions like Chromium, Molybdenum, Nickel, Vanadium, and Manganese.

Medium & High Carbon Alloys

Cr-Mo and high-strength alloy steels for heavy-duty shafts, gears, and axles.

Ni-Cr-Mo Alloys

Classic heavy-duty engineering steels with excellent toughness and fatigue resistance.

Q&T Structural Alloys

High-strength structural steels for cranes, mining trucks, and offshore structures.

High Hardness & Wear

Abrasion-resistant steels for impact zones, crushers, and armored protection.

Tool Steels

Heavy-duty tool steels for dies, cutting tools, and high-impact applications.

Shafting & Special Grades

High tensile shafting materials and ultra-high strength special alloys.
