Ratnashri Metals is a leading Supplier, Manufacturer & Exporter of Stainless Steel 304 (UNS S30400) Sheet, Stainless Steel 304 Plates, Stainless Steel 304 Coils, Stainless Steel 304 Seamless Pipes, Stainless Steel 304 Railing Pipes, Stainless Steel 304 Welded & ERW pipes & tubes.

Dual certified 304 is used as a material of construction up to 1500°F. Slight scaling begins at about 1200°F. This is the 0.04% minimum carbon version of type 304 stainless. It has general corrosion resistance similar to the low carbon 304/304L. However, it is subject to carbide precipitation in the heat affected zone (HAZ) of welds. Weldments may be sensitive to HAZ intergranular corrosion in oxidizing acid environments, and to polythionic acid stress corrosion cracking. The carbide precipitation is not harmful to high temperature mechanical properties.

304 is welded using the 22Cr 11Ni filler wire (ER308), or covered electrodes (E308). Post-weld heat treatment is not necessary for most high temperature service.
