A403 WP321H-S 90° OR 180° LR Elbow Stainless Steel BW Fitting B16.9

ASTM A403 is a balanced, austenitic, chromium steel containing columbium which takes into consideration the end of carbide precipitation, and thus intergranular corrosion. ASTM A403 is balanced out by the increases of chromium and tantalum and offers higher creep and stress rupture properties than A304 and A304L, which may also be utilized for exposures where sensitization and intergranular corrosion are of concern.The expansion of columbium likewise permits ASTM A403 to have outstanding corrosion resistance, better than that of A321. ASTM A403H is the higher carbon composition form of ASTM A403 and display enhanced high temperature and creep properties.

ASTM A403 WP321H fittings wrought austenitic stainless,grade A403 WP321H,they are used for the pressure piping systems of moderate and high temperature services.WP321H is one of the steel grade in A403 standard.Ti as a stabilizing element exists in 321H stainless steel,the H means the element Carbon content is higher than common 321 material.It is better than 321 in terms of high temperature.321H 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 WP321H is the most common stainless steel pipe fittings material.

A403 WP321H Fittings Advantages:

High strength
Resistant to high mechanical stresses
Resistant to high pressure
Resistant to high temperature
Good formability
Reusable

SS321H Fitting Classes of WP Grades

CR	Corrosion resistant grade. S through WU Classes do not apply.
WP 321H-S	Seamless
WP 321H-W	Welded, RT or UT all pipe starting material welds made with filler metal. All fitting manufacturer welds except as excluded in A/SA403 paragraph 5.4.3. If UT is substituted for RT, all welds must be examined 100% for their length as required by A/SA403 paragraph 5.6
WP 321H-WX	RT all welds with or without filler metal.
WP 321H-WU	UT all welds with or without filler metal.
WPgrade-grade-class	Insert grades (321H-321H) and class (S,W,WX, or WU). Applies to fittings meeting all chemical and physical requirements of both grades.
