X6Cr17
1.4016THE standard ferritic stainless steel — 16-18% Cr, no Ni. Non-hardenable, magnetic, lower cost than austenitic grades. Good corrosion resistance for indoor/mild environments. Used for kitchen sinks, automotive trim, washing machine drums, architectural panels, and catering equipment. Not suitable for welding thick sections (grain coarsening). AISI 430.
