Description
ASTM A403 WP304 pipe fittings mean the pipe fittings which material
is Wrought Austenitic Stainless grade A403 WP304,they are used for
the pressure piping systems of moderate and high temperature
services.ASTM A403 is the standard of pipe fittings material,it
indicates the materials properties of different kinds of stainless
steel,WP304 is one of the steel grade in this standard.304 a kind
of common stainless steel,it is widely used to make for the
manufacture of equipment and parts which needs good comprehensive
performance,corrosion resistance and formability.In order to keep
inherent corrosion resistance of stainless steel,steel must contain
more than 18% chromium and more than 8% nickel.ASTM A403 WP304 is
the most common stainless steel pipe fittings material.(ASTM A403 WP304 Standard Specification)
