How to use ASTM A403 WP304L pipe fittings?

ASTM A403 WP304L material is a common stainless steel material.It is widely used to make for equipment and parts which require a good comprehensive performance(corrosion resistance and formability).In order to keep inherent corrosion resistance of stainless steel,it must contain more than 16% chromium and more than 8% nickel.

A403 WP304L is a grade of stainless steel according to the United States ASTM standard.Comparing to other stainless steel material WP316,WP321 etc,WP304L has a cheaper cost,so it is widely used in many fields.

ASTM A403 WP304L Pipe Fittings

The ASTM A403 WP304L pipe fittings commonly should be butt welded with the A312 TP304L pipes or A182 F304L flanges or forged fittings.304L material is upgrade of 304 steel.”L” in the WP304L means the LOW carbon percent which will have a better performance when welding.The carbids precipitation will be lower in 304L welding, and the risk of intergranular corrosion.(How to reduce the risk of intergranular corrosion and test it)

ASTM A403 WP304L pipe fittings can be used in industry and ordinary occasion.It has the excellent properties that many kinds of other metal don’t have.It is a kind excellent durability and recycle material.Corresponding to the changes of the times,this kind of stainless steel pipe fittings will be widely applied in various fields in the future.
