What is the density of 316L?

8000 kg/m³ — the figure the weight calculators on this site use for 316L. The value is Outokumpu / stainless technical resources’s.

What is the chemical composition of 316L?

C ≤ 0.03, 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.

What are the mechanical properties of 316L?

Tensile ≥ 485 MPa, Yield ≥ 170 MPa, Elongation min ≥ 40 % — ASTM A240, Plate/Sheet/Strip, Annealed. Those are the standard’s requirements; the mill test certificate governs the metal delivered.
