Working with 1.4319-C700
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-C700 — frequently asked
What is 1.4319-C700 used for?
1.4319-C700 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-C700?
1.4319-C700 has a typical yield strength of 420 MPa (60.9 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 64% of stainless steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1.4319-C700 easy to machine?
Reasonably — machinability is rated fair (45/100, better than 84% 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-C700 be welded?
Yes — weldability is rated good (62/100). 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-C700?
Not anodisable; passivate (ASTM A967) after machining, and use electropolishing, BA/2B mill finish, brushing or PVD coating for appearance.
Can 1.4319-C700 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-C700?
1.4319-C700 is rated for continuous use to about 400°C (752 °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.
