What is 1.4017?
1.4017 (X6CrNi17-1) is a nickel-modified 17Cr ferritic stainless steel that offers higher toughness and slightly better corrosion resistance than plain 430, and is used for European decorative and mild-corrosion parts. Typical annealed properties are 300 MPa yield, 500 MPa tensile, 25 % elongation and 160 HB, with service to 750 °C, in annealed hot- and cold-rolled sheet, bright-annealed, cold-drawn, 1/4H and 1/2H conditions. Formability is good for the family (score 68) but corrosion resistance is still low (score 40), so it is not for chloride or marine service. Use 1.4016/430 where cost governs, or an austenitic grade where corrosion resistance drives the choice. 1.4017 has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,425°C (2,597 °F). 1.4017 has a 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. Elongation at break is 25% and the elastic modulus is 220 GPa (31.9 Msi).

Working with 1.4017
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.
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 |
| Fe | balance |
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 — frequently asked
What is 1.4017 used for?
1.4017 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?
1.4017 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 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.

What is the maximum service temperature of 1.4017?
1.4017 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.
How much does 1.4017 cost?
1.4017 is a standard-cost stainless steel ($$), cheaper than about 71% 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.
