DESCRIPTION
Dual certified 304/304H 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.

DESIGN FEATURES
Elevated temperature service to 1500°F
Corrosion resistance similar to 304/304L

TYPICAL APPLICATIONS
Pressure Vessels
Petrochemical Equipment

TENSILE REQUIREMENTS
Tensile Strength (KSI) 70
Yield Strength (KSI) 25

KSI can be converted to MPA (Megapascals) by multiplying by 6.895.
