Working with 1.4372-C1300
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-C1300 — frequently asked
What is 1.4372-C1300 used for?
1.4372-C1300 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-C1300?
1.4372-C1300 has a typical yield strength of 1,080 MPa (157 ksi) and a tensile strength of 1,350 MPa (196 ksi) — stronger than 98% of stainless steel grades. Strength varies by condition: see the 9 listed tempers.
Is 1.4372-C1300 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 with no dwell, and generous coolant; expect ~40–45 % of 1212 speeds.
Can 1.4372-C1300 be welded?
With care — weldability is rated fair (50/100). 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-C1300?
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-C1300 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-C1300?
1.4372-C1300 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 1.4372 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.
