A403 WP347H 90 45 180 Deg Elbow Stainless Pipe Fittings Corrosion Resistance 2 1/2" SCH10S

ASTM A403 WP321 pipe fittings mean the pipe fitting which material is Wrought Austenitic Stainless,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,WP321 is one of the steel grade in this standard. Ti as a stabilizing element exists in 321 stainless steel,it is better than 316L in terms of high temperature.321 stainless steel has good abrasion resistance in organic acid and inorganic acid with different concentration and temperature,especially has good abrasion resistance in oxidizing medium.It is always used in the manufacture of wear resistant acid containers and pipeline equipment.ASTM A403 WP321 is one of the most common stainless steel pipe fittings material.(ASTM A403 WP321 Standard Specification)

ASTM A403 WP321 pipe fittings are butt welding ends,commonly used to be welded with the steel pipes of A213,A49,GR.B material or API 5L GR.B material.

Standard:ASME B16.9,ASME B16.28
