1.After quenching, 440C/9Cr18Mo has high hardness and wear resistance, high temperature and low temperature dimensional stability, and is suitable for manufacturing bearings in corrosive media such as seawater, river water, nitric acid, steam and marine, such as bearings in ships and submersible pump parts, bearings in petroleum and chemical machinery, and bearings for marine instruments.
2.440B/9Cr18MoV has good rust resistance. It is a high-quality stainless steel used in the high-end batch cutting tool market. Its strength and sharpness are higher than ATS-34, and its chromium content is up to 16-18%. It is the second most commonly used stainless steel (after ATS-34). It is also the first stainless steel accepted by the cutter, and has been very popular, especially after the sub-zero treatment process is developed, this treatment enhances the toughness of the steel.
440B/9Cr18MoV /1.4112 material use:
9Cr18MoV is suitable for manufacturing parts that bear friction and work in corrosive media, such as measuring tools, stainless slicing machine tools and cutting tools, surgical blades, high wear-resistant equipment parts, etc.
