Working with 1.4376 1/4H
Is 1.4376 easy to machine?
Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed, no dwell, and generous flood coolant.
Can 1.4376 be welded?
Readily welded by GTAW/GMAW/resistance methods with 308L or over-alloyed 307/309L filler; keep heat input low and avoid preheat, no post-weld anneal normally needed on thin gauge.
Can 1.4376 be formed, bent or molded?
Excellent deep-drawing and roll-forming, but higher yield and work-hardening rate than 304 means more press force, extra springback compensation and interstage annealing on severe draws.
What surface finishes work on 1.4376?
Pickle and passivate after welding; takes BA, No.4 brushed and mirror polish well, and accepts PVD colour coating — do not anodise.

1.4376 1/4H — frequently asked
What is 1.4376 1/4H used for?
1.4376 1/4H is typically used for decorative panels, consumer goods, light structural parts and tubing. In short: lowest-nickel austenitic option; indoor decorative grade; formable, low corrosion margin.
What is the yield strength of 1.4376 1/4H?
1.4376 1/4H has a typical yield strength of 570 MPa (82.7 ksi) and a tensile strength of 900 MPa (131 ksi) — stronger than 85% of stainless steel grades. Strength varies by condition: see the 11 listed tempers.
Is 1.4376 1/4H 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, no dwell, and generous flood coolant.
Can 1.4376 1/4H be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW/resistance methods with 308L or over-alloyed 307/309L filler; keep heat input low and avoid preheat, no post-weld anneal normally needed on thin gauge.
What surface finishes work on 1.4376 1/4H?
Pickle and passivate after welding; takes BA, No.4 brushed and mirror polish well, and accepts PVD colour coating — do not anodise.
Can 1.4376 1/4H be formed, bent or molded?
Excellent deep-drawing and roll-forming, but higher yield and work-hardening rate than 304 means more press force, extra springback compensation and interstage annealing on severe draws.
What is the maximum service temperature of 1.4376 1/4H?
1.4376 1/4H is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4376 Annealed and 1.4376-C1300?
Annealed is the default condition — standard stock condition for sheet, coil and welded tube — best formability and corrosion resistance. C1300: maximum-strength cold-rolled strip for spring, clamp and tension-band applications. Yield strength is 400 MPa in Annealed versus 1,100 MPa in C1300.
