Working with 1.4319 Annealed
Is 1.4319 easy to machine?
Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed and flood coolant; avoid dwelling and re-cutting the hardened skin.
Can 1.4319 be welded?
Readily GTAW/GMAW/resistance welded with 308L/307 fillers; the low carbon avoids sensitisation, but keep heat input low to limit distortion and hot-crack risk in this low-ferrite chemistry.
Can 1.4319 be formed, bent or molded?
Excellent deep-draw and stretch behaviour when annealed, with very high work-hardening rate — allow for large springback, high press loads and interstage annealing on severe draws.
What surface finishes work on 1.4319?
Not anodisable; passivate (ASTM A967) after machining, and use electropolishing, BA/2B mill finish, brushing or PVD coating for appearance.

1.4319 Annealed — frequently asked
What is 1.4319 Annealed used for?
1.4319 Annealed is typically used for cold-formed structural parts, springs, decorative trim and automotive strip components. In short: cold-work strengthened austenitic; lower carbon than 301; deep-draw and spring strip.
What is the yield strength of 1.4319 Annealed?
1.4319 Annealed has a typical yield strength of 290 MPa (42.1 ksi) and a tensile strength of 700 MPa (102 ksi) — weaker than 72% of stainless steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1.4319 Annealed easy to machine?
Not especially — machinability is rated fair (40/100, better than 72% of stainless steel grades). Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed and flood coolant; avoid dwelling and re-cutting the hardened skin.
Can 1.4319 Annealed be welded?
Yes — weldability is rated very good (70/100). Readily GTAW/GMAW/resistance welded with 308L/307 fillers; the low carbon avoids sensitisation, but keep heat input low to limit distortion and hot-crack risk in this low-ferrite chemistry.
What surface finishes work on 1.4319 Annealed?
Not anodisable; passivate (ASTM A967) after machining, and use electropolishing, BA/2B mill finish, brushing or PVD coating for appearance.
Can 1.4319 Annealed be formed, bent or molded?
Excellent deep-draw and stretch behaviour when annealed, with very high work-hardening rate — allow for large springback, high press loads and interstage annealing on severe draws.
What is the maximum service temperature of 1.4319 Annealed?
1.4319 Annealed is rated for continuous use to about 800°C (1,472 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4319 Annealed and 1.4319-FH?
Annealed is the default condition — pick for maximum formability — deep drawing, stretch forming and parts that are welded before service. FH: maximum as-rolled strength for springs, shim stock and wear strips; very limited bending. Yield strength is 290 MPa in Annealed versus 1,100 MPa in FH.
