Difference between 300 series and 400 series stainless steelĀ
The 300 series are the austenitic stainless steel, which are non-magnetic. The 400 series are the ferritic stainless steel, which are magnetic. The stainless steel from 400 series can be divided in two groups: the ferritic properly, which generally has a higher chrome and a lower carbon; [...]
