What material is the highest permeability of stainless steel
Ferritic stainless steel has the best magnetic conductivity, and the 400 series includes ferritic stainless steels, such as 409, 430, 443, 444, 439, 436. Carbon steel, Ferritic and martensitic stainless steel, magnetic, austenitic stainless steel, non-magnetic.
Stainless steel has a variety of grades, and various brands of applications and physical and chemical properties are also far from each other, only the choice of the right is the best. Stainless steel is divided into austenite stainless steel, martensitic stainless steel and duplex stainless steel from metallographic structure, wherein austenitic stainless steel belongs to non-magnetic stainless steel, martensite and duplex stainless steel are magnetic.
Requirements of magnetic rust, if recommended for household use martensitic stainless steel, such as 410 (chromium, about 13%), 430 (chromium, about 17%), of which 430 chromium content is higher, the rust effect is better than 410, the same magnetic. Duplex stainless steel is mainly used in chemical industry, higher price, not suitable for civilian use.
