What is 1.4372?
1.4372 (X12CrMnNiN17-7-5) is the European equivalent of AISI 201 / S20100 (12Cr17Mn6Ni5N), a low-nickel austenitic stainless in which manganese and nitrogen replace part of the nickel. It is chosen where cost reduction against 304 matters but formability must be kept: annealed material runs about 420 MPa yield, 800 MPa tensile, 52 % elongation and 200 HB (92 HRB) with a formability score of 78, and it is available annealed, BA, 1/4H to FH, C1000 to C1300, cold drawn and HRAP. Oxidation-limited service reaches roughly 760 °C, but corrosion resistance is below 304 and machinability is poor; move to 304 or 316 for chloride or wet-service parts. 1.4372 has a density of 7.75 g/cm³ (0.28 lb/in³), lighter than 65% of stainless steel grades. It melts at 1,400°C (2,552 °F). 1.4372 has a yield strength of 420 MPa (60.9 ksi) and a tensile strength of 800 MPa (116 ksi) — stronger than 64% of stainless steel grades. Elongation at break is 52% and the elastic modulus is 197 GPa (28.6 Msi).

Working with 1.4372
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 — frequently asked
What is 1.4372 used for?
1.4372 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?
1.4372 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 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 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?
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 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?
1.4372 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.
How much does 1.4372 cost?
1.4372 is a budget-cost stainless steel ($), cheaper than about 90% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
