Material SS
Elevated Temperature Service to 1500 deg F
Applications Pressure Vessels,Petrochemical Equipment
Density 0.285 lb/inch3
Ultimate Tensile Strength Minimum 75,Typical 90 ksi
Yield Strength Minimum 30,Typical 35 ksi at 0.2%


Dual certified 304/304H is used as a material of construction up to 1500F. Slight scaling begins at about 1200F. 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. 304/304H 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.
