Stainless Steel – Grade 304 Sheet, Plate, Tube, Mesh & Bar

Stainless Steel – Grade 304 Sheet, Plate, Tube, Mesh & Bar

304 Stainless Steel supplied from stock in a range of bar, flat, stainless steel 304 sheet
, plate, angle and seamless tubing and pipes. Most items available for next day delivery locally and nationally.

Stainless steel types 304 and 304L. Type 304 is the most widely used and versatile of the stainless steel grades. It is also known as 18/8 (18% chromium 8% nickel). It is available in a wider range of products, forms and finishes than any other of the 300 grade stainless steels.

304 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 and other hollow-ware.

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, including stainless steel 304 sheet.
