Working with 1.4372 Annealed
Is 1.4372 easy to machine?
Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed with no dwell, and generous coolant; expect ~40–45 % of 1212 speeds.
Can 1.4372 be welded?
Readily welded by GTAW/GMAW/RSW without preheat; use 308L or high-Mn 307 filler, keep interpass low and avoid heavy heat input to limit sensitisation and N loss.
Can 1.4372 be formed, bent or molded?
Deep draws and roll forms well but work-hardens faster than 304, so allow higher press tonnage, more interstage annealing and larger springback compensation.
What surface finishes work on 1.4372?
Takes mechanical polish, No.4 hairline, BA and PVD coating well; passivation or electropolishing is recommended after fabrication, but chloride-exposed parts should be painted or upgraded to 304/316.

1.4372 Annealed — frequently asked
What is 1.4372 Annealed used for?
1.4372 Annealed is typically used for kitchenware, sinks, decorative trim, appliance housings and handrails. In short: low-nickel 304 cost substitute; strongest annealed 200-series here; not for chloride exposure.
What is the yield strength of 1.4372 Annealed?
1.4372 Annealed has a typical yield strength of 420 MPa (60.9 ksi) and a tensile strength of 800 MPa (116 ksi) — stronger than 64% of stainless steel grades. Strength varies by condition: see the 9 listed tempers.
Is 1.4372 Annealed easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% of stainless steel grades). Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed with no dwell, and generous coolant; expect ~40–45 % of 1212 speeds.
Can 1.4372 Annealed be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW/RSW without preheat; use 308L or high-Mn 307 filler, keep interpass low and avoid heavy heat input to limit sensitisation and N loss.
What surface finishes work on 1.4372 Annealed?
Takes mechanical polish, No.4 hairline, BA and PVD coating well; passivation or electropolishing is recommended after fabrication, but chloride-exposed parts should be painted or upgraded to 304/316.
Can 1.4372 Annealed be formed, bent or molded?
Deep draws and roll forms well but work-hardens faster than 304, so allow higher press tonnage, more interstage annealing and larger springback compensation.
What is the maximum service temperature of 1.4372 Annealed?
1.4372 Annealed is rated for continuous use to about 760°C (1,400 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4372 Annealed and 1.4372-C1300?
Annealed is the default condition — standard stocked condition for forming, deep drawing, welding and decorative fabrication. C1300: top cold-worked class, essentially full-hard strip for flat springs and high-load thin sections. Yield strength is 420 MPa in Annealed versus 1,080 MPa in C1300.
