Baosteel has successfully developed a Nitrogen controlled high strength martensitic stainless steel with excellent hardness and corrosion resistance for cutting tools. Now the three major domestic cutting tool manufacturing and marketing distribution places Yangjiang Guangdong, Yongkang Zhejiang and Dazu Chongqing have all adopted this product, and the monthly orders maintain above 800tns. This year, in view of this market demand, Stainless Steel Business Unit and Research Institute Stainless Steel Technology Center collaborated closely to optimize the alloy composition and production process of the stainless steel for cutting tools. After hard work, part of the technological difficulty in metallurgical process is finally broken through, so that stainless steel for cutting tools can possess good corrosion resistance while acquiring high hardness after heat treatment. Since the product was put on the market, it has been adopted by many renowned domestic cutting tool manufacturers and extensively applied in the manufacture of high end table knife, military knife, blender blade of soybean milk maker and razor blade, etc.
