Gonmo’s Cold-Rolled Medium and High Carbon Steel series is engineered for precision-critical applications across cutting, forming, suspension, and power transmission systems. Manufactured by LY Steel using advanced hydrogen annealing and clean steel technology, our products range from 0.40 mm to 6.00 mm in thickness, with coil-to-coil strength variation tightly controlled within ±15 MPa. This ensures outstanding uniformity across batches—delivering stable heat treatment response, superior flatness, and consistent formability.

With a dominant 70% share of the domestic saw blade steel market, LY Steel has become a trusted name in high-performance strip steel. The flagship grade 75Cr1, widely used in precision saws and cutting tools, was honored with the first-ever “Excellent Quality Award” in China’s high and medium carbon steel category—affirming LY Steel’sleadership in steel quality and innovation.

Versatile Grades. Tailored Applications.

• Cutting & Blades – 75Cr1, SK85, SK95, SK120: Up to 67 HRC hardness, fine carbide dispersion, and high fatigue resistance. Perfect for industrial saws, jigsaws, chef knives, and slitting tools.
