Stainless Steel 303 Sheet

Stainless Steel 303 Sheet is a variant of the basic 18-8 chromium-nickel austenitic stainless steel. It has high levels of sulfur in its composition, making it ideal for enhanced machinability, but reducing its corrosion resistance and tensile strength compared to standard 304 grade stainless steel. Its composition includes 17-19% chromium and 8-10% nickel, with the remainder being iron and trace amounts of sulfur.


Stainless Steel 303 Sheet is a non-magnetic, austenitic steel which contains 18-20% chromium and 8-10.5% nickel. This sheet offers excellent machinability, superior weldability and formability properties. It has a high corrosion resistance making it ideal for aircraft components and architectural applications such as roofing, fasteners, kitchen appliances etc. Additionally, it can be annealed to improve its ductility and is often used in the production of springs and fastening applications.
