Corrosion-Resisting Stainless Steel-JUNG YI STEEL

Corrosion-Resisting Stainless Steel

The most typical among all corrosion-resistant Stainless Steel are (1) 200 series of AISI (American Iron & Steel Institute) that denoted in 3 digits : 201, 202; 300 series (301, 302, 304, 316,…etc); 400 series (410, 420, 430,…etc) and 600 series (630, 631). (2) Sorted by different alloy elements, there are Cr. series (400 series), Cr. Ni. Series (300, 600, and dual phase steel) and Cr.-Ni-Mn series (200 series) that can naturally form a thin layer of Cr2O3 to protect the interior from corrosion. (3) By the matrix structure, there are Austenite, stainless steel (2xx, 3xx), Ferrite (44xx-409, 430, 439, 436, 445), Martensite stainless steel (4xx-410, 420), precipitation stainless steel (6xx) and duplex steel (2101, 2205)
