Applicability and limitations
Table 1 of the Japanese original 2011: SUS301-CSP, with temper 1/2H in Table 5. The hardness for that temper must not be applied to other tempers. Table 5: Vickers hardness ≥310 HV in the cold-rolled or annealed/solution-treated condition. Table 2—4 gives heat analysis, mass fraction %. Strength/elongation in Table 7 applies only when requested by the purchaser; tensile testing may be omitted for thicknesses below 0.30 mm. Values after precipitation hardening in Table 6 require assessment under the applicable treatment conditions. This standard covers cold-rolled stainless steel strip for springs; it does not establish cold-heading wire applicability, stock or supply guarantees.
