S35045

2 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.

Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Composition

ElementComposition requirement
C0.06 ~ 0.1
Mn≤ 1.5 (lower limit not stated)
P≤ 0.045 (lower limit not stated)
S≤ 0.015 (lower limit not stated)
Si≤ 1.0 (lower limit not stated)
Cr25.0 ~ 29.0
Ni32.0 ~ 37.0
Cu≤ 0.75 (lower limit not stated)
Al0.15 ~ 0.6
Ti0.15 ~ 0.6

Applicability and limitations

Table 1 gives heat-analysis mass percentages; A single value without a stated range or minimum is a maximum; unspecified elements are not entered as zero. ; Cb and Nb are the same element; Where both a formula and a fixed limit apply, the stricter limit is used. ; This is a plate, sheet and strip standard; cold-heading wire applications and actual supply require separate verification. ; Clause 4.1 also requires compliance with the applicable provisions of ASTM A480/A480M; This record displays the heat composition in Table 1; it does not establish verification of A480 or all product acceptance requirements. ; Other elements in the original table: Al 0.15–0.60 Ti 0.15–0.60; See the limits below for the specific coupled requirements.

      Applicability and limitations

      Table 1 values are mass percentages; a single value is a maximum, and an ellipsis means unspecified—no zero is inferred. Clause 7.1 requires compliance with Table 1; the general requirements of 5.1 and A999/A999M also apply. This review covers only the chemical-composition table. This is an austenitic stainless-steel pipe standard and does not establish cold-heading wire suitability or full product acceptance. Note C: the nitrogen test method is agreed between buyer and seller.
