Applicability and limitations
Table 1 in the original Japanese 2011 edition: SUS420J2-CSP; Table 5 temper condition O; The hardness for this temper condition must not be applied to other temper conditions. ; Table 5: Vickers hardness ≤247 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. ; Table 3 Note: Ni may be contained at ≤0.60%; the original table lists this as a permissible value, not as a mandatory element or a default composition for this record. ; Clause 4: SUS420J2-CSP-O shall be annealed after cold rolling.
