Applicability and limitations
Table 1 in the original Japanese 2011 edition: SUS631-CSP; Table 5 temper condition O; The hardness for this temper condition must not be applied to other temper conditions. ; Table 5: Vickers hardness ≤200 HV in cold-rolled or annealed/solution-treated condition. ; Table 2—4 gives heat-analysis mass percentages; Strength/elongation in Table 7 applies only upon request of the purchaser, and tensile tests may be omitted for thicknesses less than 0.30 mm; Values after precipitation hardening in Table 6 must be judged separately according to processing conditions. ; This standard covers cold-rolled stainless steel strip for springs; it does not establish cold-heading wire suitability, stock availability or a supply guarantee. ; Clause 4: SUS631-CSP-O shall undergo solution treatment after cold rolling; Hardness after precipitation hardening in Table 6 shall be determined separately according to processing conditions.
