Type 304 Stainless Steel is the most widely used of all Stainless Steel types. It is used in all fields of industrial, commercial and domestic manufacturing.
Type 420J2 is inexpensive and highly corrosion resistant steel. It has good corrosion resistance in mild atmosphere as well as domestic and industrial environments.
Type 439 (also known as ASTM XM-8) is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids.
Type 444 is a low carbon, low nitrogen, ferritic stainless steel that provides pitting and crevice corrosion resistance superior to most ferritic stainless steels.
