X6Cr17 Ferritic Stainless Steel Introduction
X6Cr17 (material number 1.4016) is a chromium ferritic stainless steel containing 16–18% chromium. It belongs to the ferritic class of corrosion resisting steels, offering good corrosion resistance in mildly aggressive environments, excellent formability in the annealed condition, and magnetic properties. It is non-hardenable by heat treatment and is typically supplied as plate, coil, or strip in the annealed condition. Widely used in kitchen equipment, architectural trim, and automotive exhaust systems, this grade provides a cost-effective alternative to austenitic stainless steels for many applications.
X6Cr17 Ferritic Stainless Steel Chemical Composition
Chemical composition of X6Cr17 according to EN 10088-1. The steel is a simple chromium ferritic stainless steel with controlled residual elements.
| Chemical Element | Standard Value | Remarks |
|---|---|---|
| Carbon (C) | ≤ 0.08 | Maximum, improves strength but reduces corrosion resistance if higher |

X6Cr17 Ferritic Stainless Steel Similar Alternative Ferritic Stainless Steels
| Country/Region | Standard | Grade | Remarks |
|---|---|---|---|
| Europe | EN 10088-1 | X6Cr13 (1.4000) | Lower Cr (12–14%), slightly lower corrosion resistance |
| Europe | EN 10088-1 | X2CrTi12 (1.4512) | Ti-stabilized, improved weldability and formability |
| Europe | EN 10088-1 | X6CrMo17-1 (1.4113) | Mo addition for enhanced pitting resistance |
| USA | ASTM A240 | 434 (UNS S43400) | Mo-modified 430, better corrosion resistance |
Notes:
Heavy cold deformation should be avoided as it can cause embrittlement. Post-weld annealing is recommended to restore ductility. Not suitable for chloride-rich environments (e.g., marine) without protective coatings. Magnetic properties make it unsuitable for non-magnetic applications.
