T/CSTA 0001-2020 Spring stainless steel wire bar
Basic Information
Scope
Main technical content: This standard specifies the ordering content, dimensions, shapes, weights, and allowable deviations of stainless steel wire rod for springs, as well as technical requirements, test methods, inspection rules, packaging, marking, and quality certificates. This standard applies to hot-rolled stainless steel wire rod with a diameter of 4.5mm to 40mm used in spring manufacturing. By combining the latest melting control technology and size and surface quality control technology with practical applications, and based on the actual needs of spring-grade stainless steel wire rod production, this standard adds four new grades of spring-grade stainless steel wire rod products and their quality requirements, further strictly controls element content, stipulates key technical indicators such as high-temperature relaxation and creep performance, and enhances the guiding significance of standards in specialized fields.
