316 Stainless Steel Bar (316/316L, ASTM A276)

Arch Metals supplies 316 stainless steel bar, including low-carbon 316L, from Dallas, Texas, to marine, chemical, medical and oil and gas customers across Texas and the surrounding states. 316 is an austenitic stainless steel with 2–3% molybdenum, which gives it much better resistance to chlorides, pitting and acids than 304. We supply annealed 316 and 316L bar to ASTM A276/A479 and AMS 5648/5653 with certified material and saw cutting to length. Request a quote and we’ll confirm sizes and availability.

316 Stainless Steel Forms

  • Round bar, annealed
  • Hex, square and flat bar
  • 316L dual-certified bar on request
  • Plate and sheet on request

Size availability changes with mill supply. Send us your sizes through our quote request form and we’ll confirm stock, lead time and pricing.

316 Stainless Steel Condition and Specifications

  • 316 annealed bar (ASTM A276, ASTM A479, AMS 5648): solution annealed. 316 is not hardenable by heat treatment; strength comes only from cold work.
  • 316L annealed bar (ASTM A276, ASTM A479, AMS 5653): low carbon (0.03% max) for welded parts. Bar is often dual-certified 316/316L.
  • Equivalent designations (UNS S31600 / S31603): also called Type 316, marine-grade stainless and 1.4401 (EN).

Typical Properties of Annealed 316 Stainless Steel

  • Ultimate tensile strength: about 85 ksi (585 MPa)
  • Yield strength: about 35 ksi (240 MPa)
  • Elongation: about 50%
  • Hardness: about 80 HRB
  • Density: 0.289 lb/in³ (8.0 g/cm³)
  • Chemistry: about 17% chromium, 12% nickel and 2–3% molybdenum

These are typical values for annealed bar. Guaranteed minimums vary by specification, condition and size, so check the governing spec or your mill cert for design values.

Why Engineers Choose 316 Stainless Steel

The molybdenum in 316 protects it from pitting and crevice corrosion in salt water, de-icing salts, bleach and many process chemicals that would attack 304 stainless steel bar. It also has better strength at elevated temperature. For galling resistance or higher strength in corrosive service, see Nitronic 50. Common uses for 316 include:

  • Marine hardware, shafts and fittings
  • Chemical and pharmaceutical process equipment
  • Oil and gas valve and pump components
  • Medical and laboratory equipment
  • Food processing equipment exposed to salt or acids

316 Stainless Steel FAQs

What is the difference between 316 and 316L stainless steel?

316L has a lower carbon limit (0.03% max), which prevents sensitization in weld zones. Much bar stock is dual-certified to both 316 and 316L.

Is 316 stainless steel better than 304?

For corrosion resistance, yes. 316 holds up much better in chlorides and acids. 304 costs less and is fine for most indoor and non-marine applications.

Is 316 stainless steel magnetic?

Annealed 316 is essentially non-magnetic, and it stays less magnetic than 304 after cold work.
