In China’s GB standards, 9Cr18 and 95Cr18 actually refer to the same type of steel. 95Cr18 is the new designation for 9Cr18 steel. <\/p>\n\n\n\n

The old designation 9Cr18 originates from the GB\/T 1220-1992 standard. It is primarily based on carbon and chromium content, with \u201c9\u201d representing a carbon content of approximately 0.9% and \u201c18\u201d representing a chromium content of approximately 18%.<\/p>\n\n\n\n

The new grade 95Cr18 is named according to the latest GB\/T 1220-2007 standard. The new naming convention is more standardized, with \u201c95\u201d representing a carbon content of approximately 0.95%, which more accurately indicates the carbon content compared to the old grade.<\/p>\n\n\n\n

95Cr18 steel is a high-carbon, high-chromium martensitic stainless steel. It has high hardness, wear resistance, and corrosion resistance. This steel also exhibits good hot plasticity and low heat treatment deformation tendencies.<\/p>\n\n\n\n

For the improved version, “9Cr18Mo<\/mark><\/a>” (also known as AISI<\/mark><\/a> 440C<\/mark><\/a>), the composition includes Molybdenum (Mo) typically in the range of 0.40% to 0.70%.<\/p>\n\n\n\n
