What is SS 316L?
SS 316L (UNS S31603, EN 1.4404) is an austenitic stainless steel containing 16.0–18.0% chromium, 10.0–14.0% nickel and 2.00–3.00% molybdenum. Low-carbon 316 — the standard grade for pharma, biotech and welded chemical equipment. It is non-magnetic in the annealed condition, has a density of 7.98 g/cm³ and a minimum tensile strength of 485 MPa, and is used mainly for pharma reactors and vessels, cleanroom panels and bioprocess piping.

SS 316L price compared with 304
Same band as 316 — clearly above 304, well below 904L and the nickel alloys. For today's rate, send us your size and quantity.
Our advice
Like 304/304L, most mills supply dual-certified 316/316L. Ask for it if your drawing calls for either grade.
Values are typical ASTM A240 limits for flat products and are for guidance only. Always refer to the mill test certificate supplied with the material.
