ASTM A403 WP304H Elbows, A403 304H pipe fitting,elbow,tee,reducer,caps
ASTM A403 WP304H has a high carbon content in chemical compositions.ASTM A403 WP304H normally is used for the pressure piping systems of moderate and high temperature services. WP304H is a kind of heat and corrosion resistant steel.It has a good pipe bending,welding performance,heat and corrosion resistance,high rupture strength and stability,also the cold deformation ability is very good.It could be used up to 650°C,oxidation temperature up to 850°C.(ASTM A403 WP304H Standard Specification)

304L stainless steel, which is the low carbon form, and 304H stainless steel, which is the high carbon form. 304L has a maximum of 0.3% carbon and 304H has between 0.04 and 0.1% carbon which affords it a better strength at higher temperatures.
So ASTM A403 WP304H PIPE FITTINGS are mainly used for high-temperature applications as it offers higher strength at temperatures above about 1000° F (550° C) and up to 1500° F (800° C.)
