Applicability and limitations
Edition 2003, round stainless spring wire, mass fraction wt%. Footnote B to Table 1: values without ranges are maxima; blanks mean unspecified and are not replaced with zero. Table 1UNS, S24100. Mechanical properties for categories such as A/B, or for cold-drawing and subsequent ageing conditions, cannot be inferred from the composition table. This edition does not list 2205; similar grades are not used to fill the gap. The original 2018 and 2025 reaffirmed editions have not been verified. Spring-wire use does not automatically establish cold-heading suitability; no supply product is added automatically.
