ASTM A403 WP304H is a kind of common stainless steel material.It is widely used to connect the piping systems in equipment and pipelines which require a good comprehensive performance(heat and corrosion resistance).
ASTM A403 WP304H stainless steel pipe fittings should be connected with the 304H grade pipes or fittings,not 304L material pipe fittings.The “H” means the material has a high carbon content which make the material has a very good heat resistance.(What is ASTM A403 WP304H pipe fitting?)
When the ASTM A403 WP304H pipe fittings connected to a 304 material,the chemical composition should be checked for the carbon ratio.The welder should avoid the welding joint between the 304H and 304L material.If necessary to connect a 304H and 304L pipe system,it is better to use a flange connection.
ASTM A403 WP304H is excellent durability and recycle material.Corresponding to the changes of the times,this kind of stainless steel pipe fittings could be widely used in various fields.
