Product Description

Product Description

SPECIAL ALLOY STEEL BARS
 
Special alloy steel bars (commonly referred to as special steel rods or alloy round bars) are high-performance engineering bars engineered for superior strength, wear resistance, and fatigue life.
 
Available in industry grades such as 20CrMnMo, 20CrMnTi, 16MnCr5, 40CrNiMoA and other carburizing or quenched & tempered alloys, these bars are optimized for case-hardening, precise dimensional tolerances, and customizable heat-treatment (carburizing, quench & temper, nitriding).
