CTS B70P is a high-chromium air-hardening steel that is a powder metallurgy derivative of Carpenter’s CRB-7 alloy. It offers comparable corrosion resistance to 440C—long an industry standard—but with the advantages of enhanced wear resistance and increased hardness capability. The addition of molybdenum, vanadium, and niobium to this advanced alloy, in conjunction with the uniform carbide structure that results from the powder metallurgy process, greatly improve edge retention. Its alloy composition also enhances this steel’s grinding and polishing characteristics, making it an ideal material for high-performance knife blades.
