What is 1.4369?
1.4369 (X11CrNiMnN19-8-6) is a nitrogen-strengthened, reduced-nickel CrNiMn austenitic stainless that delivers strength and corrosion resistance in the range of standard 300-series grades at lower material cost. Nitrogen and manganese lift the annealed level to about 400 MPa yield, 750 MPa tensile, 48 % elongation and 210 HB (95 HRB), and it is available annealed, BA, cold drawn, hot rolled and in C700 to C1150 cold-worked tempers for fasteners and structural strip. The trade-offs are lower machinability (score 30), moderate weldability (65) and corrosion resistance below 304 (score 55) at the 0.08–0.15 %C level. Use 1.4301 (304) where chloride exposure or as-welded corrosion performance governs. 1.4369 has a density of 7.8 g/cm³ (0.282 lb/in³), heavier than 50% of stainless steel grades. It melts at 1,390°C (2,534 °F). 1.4369 has a yield strength of 400 MPa (58 ksi) and a tensile strength of 750 MPa (109 ksi) — stronger than 57% of stainless steel grades. Elongation at break is 48% and the elastic modulus is 200 GPa (29 Msi).

Working with 1.4369
Is 1.4369 easy to machine?
Work-hardens rapidly like 304 but harder still due to nitrogen — use rigid setups, sharp coated carbide, positive rake, heavy positive feed and generous coolant; avoid dwelling.
Can 1.4369 be welded?
Weldable by TIG/MIG/resistance methods with 307/308L-type or high-Mn fillers; keep heat input low and avoid post-weld sensitisation from the 0.08–0.15 %C level in corrosive service.
Can 1.4369 be formed, bent or molded?
Excellent deep-drawing and bending in the annealed state, though higher press tonnage and stronger springback compensation are needed than for 304; interstage annealing for severe draws.
1.4369 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Chigher C than 304; sensitisation risk after welding | 0.08 – 0.15 | 0.11 |
| Si | ≤ 1 | 0.5 |
| Mnpartial nickel substitute | 5 – 7 | 6 |
| P | ≤ 0.05 | |

| Fe | balance |
What surface finishes work on 1.4369?
Takes 2B, BA and mirror polishes well; passivate or electropolish after fabrication — do not anodise. Manganese content can make pickling and weld-scale removal slightly slower.

1.4369 — frequently asked
What is 1.4369 used for?
1.4369 is typically used for structural fasteners, kitchen equipment, architectural trim and automotive trim parts. In short: nitrogen-strengthened low-nickel austenitic; higher strength than 304; cost-driven 300-series substitute.
What is the yield strength of 1.4369?
1.4369 has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 750 MPa (109 ksi) — stronger than 57% of stainless steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1.4369 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 70% of stainless steel grades). Work-hardens rapidly like 304 but harder still due to nitrogen — use rigid setups, sharp coated carbide, positive rake, heavy positive feed and generous coolant; avoid dwelling.
Can 1.4369 be welded?
Yes — weldability is rated good (65/100). Weldable by TIG/MIG/resistance methods with 307/308L-type or high-Mn fillers; keep heat input low and avoid post-weld sensitisation from the 0.08–0.15 %C level in corrosive service.
What surface finishes work on 1.4369?

What is the maximum service temperature of 1.4369?
1.4369 is rated for continuous use to about 800°C (1,472 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4369 Annealed and 1.4369-C1150?
Annealed is the default condition — standard stocked condition: maximum ductility and corrosion resistance for deep drawing, bending and welding.
