Chemical composition of 316L stainless steel plate

Description

Chemical Composition & Equivalent Grade List of 316L Stainless Steel Plate

Equivalent grade cross-reference for 316L stainless steel plate is as follows: Under GB/T20878-2007, the numeric designation is S31603, with the grade name 022Cr17Ni12Mo2, and its former designation 00Cr17Ni12Mo2. Per ASTM A959 (US standard), it is marked S31603 / 316L. Under Japanese JIS G4303, JIS G4311 and JIS G4305 standards, it is designated SUS316L. For European standards EN10088-1 and EN10095, the grade is X2CrNiMo17-12-2 (1.4404).

The chemical composition (element content) of 316L stainless steel plate: Carbon (C): ≤0.03% Silicon (Si): ≤0.75% Manganese (Mn): ≤2.00% Phosphorus (P): ≤0.045% Sulfur (S): ≤0.03% Nickel (Ni): 10.0–14.0% Chromium (Cr): 16.0–18.0% Molybdenum (Mo): 2.0–3.0%

Note on standard differences: ASTM specifies nickel content of 10~14% for 316L, while JIS requires nickel content of 12~15%. There is a 2% difference in nickel range between these two standards. This difference has a noticeable impact on material cost. Therefore, buyers need to confirm whether the material is supplied to ASTM or JIS specification when placing orders.

Purchasers may compare the chemical composition of these two variants to select the correct stainless steel plate that meets project requirements.
