What is 9cr18mov steel? What are the applications of 9cr18mov steel?

9Cr18MoV steel has good rust resistance. It is a high-quality stainless steel currently used in the high-end batch tool market. Its strength and sharpness are better than ATS-34, and its chromium content is as high as 16-18%. It is the second most commonly used stainless steel (second In ATS-34), it is also the first stainless steel accepted by knifemakers, and has always been very popular, especially after the sub-zero treatment process was developed, this treatment strengthened the toughness of the steel. Used in the manufacture of stainless slices, mechanical cutting tools and cutting tools, surgical blades, high wear-resistant equipment parts, etc. Heat treatment specifications: 1) Annealing, 800~920℃ slow cooling; 2) Quenching, 1050~1075℃ oil cooling; 3) Tempering, 100~200℃ air cooling. Metallographic structure: The structure is characterized by martensite. Delivery status: Generally, delivery is in the heat treatment state, and the type of heat treatment is specified in the contract; if it is not specified, the delivery is in the non-heat treatment state. Hardness: annealing, ≤269HB; quenching and tempering, ≥58HRC
