What is E316L-SA?
E316L-SA is E316L heat treated to SA — use when the fabrication is solution annealed after welding — ferrite dissolves, strength drops, ductility and corrosion resistance peak. E316L-SA has a yield strength of 300 MPa (43.5 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 68% of stainless steel grades.

Working with E316L-SA
Is E316L easy to machine?
Deposited weld metal work-hardens fast — use sharp carbide, positive rake, heavy feed and flood coolant; grind rather than mill for dressing.
Can E316L be welded?
Redry electrodes 250–350 °C/1–2 h, DCEP (or AC for -16), short arc, stringer beads, interpass ≤150 °C; keep 3–10 FN ferrite to avoid hot cracking.
Can E316L be formed, bent or molded?
Weld metal is ductile enough for moderate cold straightening but avoid heavy cold work over the fusion line; peening only with control.
What surface finishes work on E316L?
Remove all slag and heat tint, then pickle/passivate (ASTM A380/A967) or electropolish to restore the passive film — mechanical brushing must use stainless-only wire.

E316L-SA — frequently asked
What is E316L-SA used for?
E316L-SA is typically used for pressure vessels and piping, food and pharmaceutical equipment, marine and offshore fabrication and chemical tanks. In short: most-used Mo stainless filler; low-carbon, sensitization resistant; corrosion score 78.
What is the yield strength of E316L-SA?
E316L-SA has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is E316L-SA easy to machine?
Not especially — machinability is rated fair (36/100, better than 57% of stainless steel grades). Deposited weld metal work-hardens fast — use sharp carbide, positive rake, heavy feed and flood coolant; grind rather than mill for dressing.
Can E316L-SA be welded?
Yes — weldability is rated excellent (92/100). Redry electrodes 250–350 °C/1–2 h, DCEP (or AC for -16), short arc, stringer beads, interpass ≤150 °C; keep 3–10 FN ferrite to avoid hot cracking.
What surface finishes work on E316L-SA?
Remove all slag and heat tint, then pickle/passivate (ASTM A380/A967) or electropolish to restore the passive film — mechanical brushing must use stainless-only wire.
Can E316L-SA be formed, bent or molded?
Weld metal is ductile enough for moderate cold straightening but avoid heavy cold work over the fusion line; peening only with control.
What is the maximum service temperature of E316L-SA?
E316L-SA is rated for continuous use to about 425°C (797 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between E316L-16 and E316L-SA?
E316L-16 is the default condition — default all-position electrode (Chinese A022); smooth arc, easy slag release, AC or DCEP. SA: use when the fabrication is solution annealed after welding — ferrite dissolves, strength drops, ductility and corrosion resistance peak. Yield strength is 420 MPa in E316L-16 versus 300 MPa in SA.
