Applicability and limitations
Original text A493−09(Reapproved2013), PDF1 header and PDF2 Table 1
note A–B, wt%. ; Values in Table 1 are maxima unless expressly stated otherwise; Blank elements are unspecified and are not entered as zero. ; This standard covers stainless steel wire and wire rod for cold heading or cold forging; Delivery condition, diameter, surface and actual supply still require confirmation; mechanical-property Table 2 requires separate verification.
