What type of stainless steel is magnetic stainless steel?
There are many kinds of stainless steel. They can be divided into several groups according to the organizational structure at normal temperature:1, austenite type: such as 304, 321, 316, 310, etc is non-magnetic or weak magnetic.2. martensite or ferrite: such as 430, 420, 410 and so on, is magnetic.
1, 420- type "cutting class" martensitic steel, similar to Brandt's first high chromium stainless steel this. Also used in surgical knives, which can be made very bright.2 model 430- ferritic stainless steel for decorative purposes, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.3, 440- type high strength cutting tool steel, carbon is slightly higher, after appropriate heat treatment to obtain a higher yield strength and hardness can reach 58HRC, which belongs to the most hard stainless steel column. The most common example is razor blades".
Model with magnetic stainless steel: martensite or ferrite: such as 430, 420, 410 and so on, is magnetic.
