Product Overview
We supply ASTM chromium alloy steel G51320, H51320, G51350, H51350. Our products include hot rolled plates, hot rolled bars and precision cold finished bars with stable chemical composition and even metallographic structure.
Grade performance features
G51320: Medium carbon chromium steel with balanced mechanical properties for common medium-stress structural parts.
H51320: High-purity hot rolled blank of 51320, stable quality for mass production of standard forgings.
G51350: Higher carbon grade with higher hardness and tensile strength, applicable to parts bearing larger load and friction abrasion.
H51350: Clean hot rolled raw material that satisfies the production requirements of precision medium-load forgings.
Processing & quality control
Available processes: cutting, cold drawing, hot forging, quenching & tempering and precision machining. Every batch will go through strict inspection with complete test documents for customer acceptance.
Main application fields
General mechanical transmission shafts, automobile ordinary gears, high-strength bolts, fixture parts and agricultural machinery structural forgings.
Export packaging
Wrap steel materials with anti-rust waterproof paper and lock with steel strips. Precision bright bars are packed into plywood cases to avoid scratches, deformation and rust during long-distance ocean shipment.
