A312 TP316L
1 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.

Carbon-equivalent reference
Estimates are presented separately for each applicable composition condition. Match the actual ordering conditions; ranges must not be combined.
Ordinary Table 1 condition (special footnote conditions not applicable)
Footnote D: outside diameter <12.7mm, or average wall thickness <1.20mm (minimum wall thickness <1.10mm), or both, with multiple drawing passes required
Composition record (conditional branches apply; this is not an unconditional requirement)
| Element | Composition requirement |
|---|---|
| C | ≤ 0.035 (lower limit not stated) |
| Mn | ≤ 2.0 (lower limit not stated) |
| P | ≤ 0.045 (lower limit not stated) |
| S | ≤ 0.03 (lower limit not stated) |
| Si | ≤ 1.0 (lower limit not stated) |
| Cr | 16.0 ～ 18.0 |
| Ni | 10.0 ～ 14.0 |
| Mo | 2.0 ～ 3.0 |
Applicability and limitations
Table 1, mass percent; A single value is a maximum; ellipses mean unspecified and are not entered as zero. ; Clause 7.1 requires compliance with Table 1; The general A999/A999M requirements in Clause 5.1 still apply; only the chemical-composition table was checked in this batch. ; Austenitic steel pipe standard; This does not directly establish cold-heading wire suitability or compliance with all product acceptance requirements. ; Footnote C: the nitrogen-analysis method is agreed between purchaser and supplier. ; Footnote D: outside diameter <12.7mm, or average wall thickness <1.20mm (minimum wall thickness <1.10mm), or both, with multiple drawing passes required; The C maximum is 0.04%; the actual product condition must be selected.
