Common questions

01What is the density of 316?
8000 kg/m³ — the figure the weight calculators on this site use for 316. The value is Outokumpu / stainless technical resources’s.
02What is the chemical composition of 316?
C ≤ 0.08, Si ≤ 0.75, Mn ≤ 2, P ≤ 0.045, S ≤ 0.03, Cr 16–18, Ni 10–14, Mo 2–3, N ≤ 0.1, in mass %, to ASTM A240. An element the standard sets no requirement for is left blank here rather than written as zero.
03What are the mechanical properties of 316?
Tensile ≥ 515 MPa, Yield ≥ 205 MPa, Elongation min ≥ 40 % — ASTM A240, Plate/Sheet/Strip, Annealed. Those are the standard’s requirements; the mill test certificate governs the metal delivered.
04What is 316 used for?
Marine, chemical, food, architectural
