Working with 1.4017 Annealed
Is 1.4017 easy to machine?
Machines more easily than austenitic 304 — use sharp positive-rake carbide, moderate speed and rigid setup to avoid built-up edge; chips are stringy, so use chipbreakers and generous coolant.
Can 1.4017 be welded?
Weldable by TIG/MIG/resistance with low heat input and no preheat above ~150 °C; HAZ grain coarsening reduces toughness, so use 309L or 430Nb filler and avoid multi-pass buildup on thick sections.
Can 1.4017 be formed, bent or molded?
Good deep drawing and bending in the annealed condition (better n and toughness than plain 430); avoid severe stretch forming and allow larger bend radii across the rolling direction; roping/ridging can appear on heavily drawn panels.
What surface finishes work on 1.4017?
Not anodizable; passivate in nitric acid after fabrication, and use bright-annealed or buffed/electropolished surfaces for decorative work — PVD coloring and clear lacquer are common.
1.4017 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 |
|---|---|---|
| C | ≤ 0.08 | 0.05 |
| Si | ≤ 1 | 0.5 |
| Mn | ≤ 1 | 0.5 |
| P | ≤ 0.04 | 0.03 |
| S | ≤ 0.02 | 0.01 |
| Cr | 16 – 18 | 17 |
| NiNi addition distinguishes 1.4017 from 1.4016; some mill specs quote 1.2–1.6 | 1 – 1.5 | 1.2 |

1.4017 Annealed — frequently asked
What is 1.4017 Annealed used for?
1.4017 Annealed is typically used for decorative trim, appliance components and mild-corrosion fasteners. In short: toughest 17Cr ferritic; deep-draws better than 430; ni-modified decorative grade.
What is the yield strength of 1.4017 Annealed?
1.4017 Annealed has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 500 MPa (72.5 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is 1.4017 Annealed easy to machine?
Reasonably — machinability is rated good (55/100, better than 94% of stainless steel grades). Machines more easily than austenitic 304 — use sharp positive-rake carbide, moderate speed and rigid setup to avoid built-up edge; chips are stringy, so use chipbreakers and generous coolant.
Can 1.4017 Annealed be welded?
Yes — weldability is rated good (55/100). Weldable by TIG/MIG/resistance with low heat input and no preheat above ~150 °C; HAZ grain coarsening reduces toughness, so use 309L or 430Nb filler and avoid multi-pass buildup on thick sections.
What surface finishes work on 1.4017 Annealed?
Not anodizable; passivate in nitric acid after fabrication, and use bright-annealed or buffed/electropolished surfaces for decorative work — PVD coloring and clear lacquer are common.
Can 1.4017 Annealed be formed, bent or molded?
Good deep drawing and bending in the annealed condition (better n and toughness than plain 430); avoid severe stretch forming and allow larger bend radii across the rolling direction; roping/ridging can appear on heavily drawn panels.
What is the maximum service temperature of 1.4017 Annealed?
1.4017 Annealed is rated for continuous use to about 750°C (1,382 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4017 Annealed and 1.4017-CD?
Annealed is the default condition — standard stocked condition for decorative panels, appliance parts and drawn components. CD: cold drawn bar for turned parts needing tight tolerance and higher strength than annealed. Yield strength is 300 MPa in Annealed versus 480 MPa in CD.
