10Cr17 Ferritic Stainless Steel Plate/Coil per GB/T4237 Introduction
10Cr17 (former designation 1Cr17) is a ferritic stainless steel standardized in China under GB/T 4237 for hot rolled plates and coils. It contains approximately 17% chromium, which provides good corrosion resistance in mildly aggressive environments. The alloy is magnetic, non-hardenable by heat treatment, and offers excellent oxidation resistance up to 800 °C intermittently.
- Excellent formability and deep drawability in the annealed condition
- Moderate strength with yield strength ≥205 MPa and tensile strength ≥450 MPa
- Widely used in kitchenware, architectural trim, and automotive exhaust components
- Not recommended for high-temperature structural applications above 500 °C due to 475 °C embrittlement

Notes:
Delivery condition: Hot-rolled plate is supplied in annealed and pickled condition; cold-rolled coil/strip can be bright annealed, or annealed and descaled. Welding: Preheating is not required, but post-weld annealing at 760-815 °C is recommended to restore ductility and corrosion resistance if the weld zone cooling rate was rapid. Temperature limitation: Prolonged exposure to temperatures between 400-500 °C may cause 475 °C embrittlement; avoid use in high-temperature structural applications above 500 °C. Surface finish: Available in various finishes such as No.1, 2B, BA, and No.4.
