Description

303 steel is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is a free machining modification of the basic 18% chromium and 8% nickel stainless steel.

303 stainless steel is a popular and versatile grade known for its exceptional corrosion resistance and machinability. Belongs to the austenitic stainless steel family, 303 stainless is characterized by its non-magnetic properties and high levels of chromium and nickel content. The inclusion of sulfur in its composition enhances its machinability, making 303 steel plate a preferred choice in applications where intricate and precise machining is required.
