AISI 431 (S43100) stainless steel SS sheet plate coil

AISI 431 (S43100) stainless steel sheet coil significantly improves its comprehensive performance through optimized hot rolling process, with yield strength and tensile strength reaching over 650MPa and 850MPa respectively, and elongation rate increased to 15% -20%. 431 stainless steel material is composed of 15% -17% chromium (Cr) and 1.25% -2.5% nickel (Ni) as the core components, combined with ≤ 0.20% carbon (C) control, balancing corrosion resistance and processing adaptability. It is suitable for aviation grade thin-walled components, chemical equipment liners, and precision instrument parts. Its martensitic structure has a hardness of 58-60HRC after quenching and tempering, and exhibits stable corrosion resistance in marine atmosphere and weak acidic alkaline environment.

In the processing technology, the S43100 SS sheet plate coil adopts the rolling strategy of "coarse first, fine later", and reduces the surface oxide layer by optimizing temperature and speed parameters to ensure the smoothness and dimensional accuracy of the plate. AISI 431 material supports forming processes such as stamping and welding, and is widely used in the fields of medical equipment, ship shock absorbers, and high-end tool manufacturing. Its physical characteristics include a density of 7.7g/cm³ and magnetic properties, combined with its high cost-effectiveness, making it an ideal choice for high load and strong corrosion scenarios.
