304 Stainless Steel

We are suppliers of 304 and 304L Stainless Steel in a wide range of bar, flat, sheet, plate, angle and seamless tubing and pipes. Reliable local and nationwide delivery.

Stainless steel types 304 and 304L. Type 304 is the most versatile and widely used stainless steel. It is also known as 18/8 from the nominal composition of type 304 being 18% chromium and 8% nickel.

The most versatile and widely applied of the 300 series Stainless Steels. It has excellent forming and welding characteristics. AISI 304 stainless can be deep drawn more severely than Types 301 and 302 without immediate heat softening, a characteristic that has made this grade dominant in the manufacture of drawn stainless steel parts such as sinks, splashbacks and saucepans.

Type 304 stainless steel also has outstanding welding characteristics. Post-weld annealing is not required to restore the excellent performance of this grade in a wide range of mildly corrosive conditions.

Type 304L does not require post-weld annealing and finds extensive use in heavy gauge components where freedom from carbide weld precipitation is often required.
