SK95 Cold Rolled Steel Strip — Recommended for High-Wear-Resistant Circular Saw Blades and Hard Cutting Tools
SK95 cold rolled steel strip features fine and uniform grain structure, high surface flatness, and excellent laser cutting forming performance. It is widely used for manufacturing premium wear-resistant circular saw blade substrates and ultra-thin cutting tools. The product undergoes precision cold rolling and spheroidizing annealing, offering high dimensional accuracy and excellent surface quality. After quenching, its hardness and wear resistance surpass those of SK85 and 75Cr1, making it a preferred material for saw blade substrates operating under heavy loads and high wear conditions.

SK95 is a high-carbon tool steel with carbon content at the higher end among carbon tool steels. The elevated carbon content significantly improves hardenability and wear resistance. Strict control of sulfur and phosphorus impurities ensures high steel purity and strong heat treatment stability, making it suitable for manufacturing high-strength, high-wear-resistant saw blades and cutting tools for long-term high-speed operation.
