300 series stainless steel is an alloy material containing iron, carbon, nickel and chromium. It is non-magnetic and has excellent forgability and corrosion resistance. According to AISI standards,
stainless steel is represented by three Arabic numerals. The first digit indicates the category, and the second or third digit indicates the ordinal number. Like our common first number 2, 3, 4,
represents the different stainless steel categories:
2: Cr-Ni-Mn (200 series)
3: CR-Ni (300 series)
4: Cr (400 series)
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
