Evaluation of hardness and corrosion resistance are important indicators of the level of quality tools. But in the stainless steel manufacturing process, the hardness and corrosion resistance of the shift, which is a stainless steel industry recognized technical problems. This decision is a tool manufacturing power in our country although most tools are for export, but the manufacturing quality is not high status tool. My tool manufacturers eager to solve the material hardness and corrosion resistance can also enhance the conflict.

    Baosteel successfully developed a kind of hardness and corrosion resistance of the tool with superb control of high-strength nitrogen martensitic stainless steel, a market it has been the customers. Currently, the domestic manufacture and market the three major distribution center tool - Yangjiang, Guangdong, Zhejiang and Chongqing Dazu Yongkang adopt the product, orders a month to maintain the volume of 800 tons.

    This year, the response to this market demand, stainless steel division and the Institute of Technology Center in close collaboration, the tool to use stainless steel alloy composition and process were optimized. After efforts to finally break through some of the metallurgical process of technical problems, the tool to use stainless steel for high hardness after heat treatment at the same time, also has good corrosion resistance. The product on the market, who has been using several well-known tool manufacturer, widely used in high-end knives, swords, soybean milk stirring blade, razor blades and other manufacturing.

    At present, Baosteel has been on the product for a series of national patents, and access to high-tech achievements of Shanghai identified.
