Working with 1.4511 Annealed
Is 1.4511 easy to machine?
Machines like 430 (~55 % of 1212): use sharp positive-rake carbide, rigid setup, generous coolant and avoid dwelling to prevent work-hardened glaze; free-machining versions are not available.
Can 1.4511 be welded?
Excellent as-welded corrosion resistance thanks to Nb stabilization — GTAW/GMAW/laser with 430Nb/309L filler or autogenous; keep heat input low to limit grain coarsening and weld-metal embrittlement.
Can 1.4511 be formed, bent or molded?
Good deep-drawing and roll-forming behaviour with low springback versus austenitics; use larger bend radii than 304 and avoid heavy stretch forming due to lower n-value.
What surface finishes work on 1.4511?
Passivate or electropolish after pickling for best surface; takes brushed, 2B or BA finishes well, can be plated or PVD-coated, but cannot be anodized.
1.4511 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 |
|---|---|---|
| Clow carbon, Nb-stabilized | ≤ 0.05 | 0.02 |
| Si | ≤ 1 | 0.4 |
| Mn | ≤ 1 | 0.4 |
| P | ≤ 0.04 | 0.03 |
| S | ≤ 0.02 | 0 |
| Cr | 16 – 18 | 17 |
| NbNb ≥ 12×C; stabilizer | 0.3 – 1 | 0.5 |

1.4511 Annealed — frequently asked
What is 1.4511 Annealed used for?
1.4511 Annealed is typically used for exhaust components, architectural trim, tubing and welded assemblies. In short: nb-stabilized 17Cr ferritic; ductile as-welded HAZ; exhaust-grade ferritic.
What is the yield strength of 1.4511 Annealed?
1.4511 Annealed has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 470 MPa (68.2 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 1.4511 Annealed easy to machine?
Reasonably — machinability is rated fair (52/100, better than 91% of stainless steel grades). Machines like 430 (~55 % of 1212): use sharp positive-rake carbide, rigid setup, generous coolant and avoid dwelling to prevent work-hardened glaze; free-machining versions are not available.
Can 1.4511 Annealed be welded?
Yes — weldability is rated very good (75/100). Excellent as-welded corrosion resistance thanks to Nb stabilization — GTAW/GMAW/laser with 430Nb/309L filler or autogenous; keep heat input low to limit grain coarsening and weld-metal embrittlement.
What surface finishes work on 1.4511 Annealed?
Passivate or electropolish after pickling for best surface; takes brushed, 2B or BA finishes well, can be plated or PVD-coated, but cannot be anodized.
Can 1.4511 Annealed be formed, bent or molded?
Good deep-drawing and roll-forming behaviour with low springback versus austenitics; use larger bend radii than 304 and avoid heavy stretch forming due to lower n-value.
What is the maximum service temperature of 1.4511 Annealed?
1.4511 Annealed is rated for continuous use to about 815°C (1,499 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
