Main technical content: The group standard "T/JXII 0001—2023 Cold-Rolled Stainless Steel Strip for Razor Blades" mainly stipulates the classification, code, order content, dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, marking, and quality certificates of high-carbon martensitic stainless steel 70Cr13 and 70Cr13MoV used for razor blades. It is applicable to cold-rolled wide steel strips with a thickness of 0.05 mm to 3.00 mm used for razor blades, longitudinally cut wide steel strips, and their coiled and cut-to-size steel strips. 70Cr13 and 70Cr13MoV are special stainless steel cold-rolled strips for razor blades. There are no provisions on their chemical composition and performance in other national or industry standards. Here, the chemical composition range and delivery mechanical properties of these materials are clearly specified.
