WP316L Austenitic Stainless Steel Equal Tee

Engineered for corrosive environments, ASTM A403 WP316L equal tees provide superior chloride resistance due to molybdenum-enhanced austenitic structure. These seamless/welded butt-welding fittings comply with ASME B16.9 dimensional standards and ASTM A403 material specifications, ideal for high-purity piping systems.

1. Chemical Composition (ASTM A403)

Guaranteed corrosion resistance through controlled alloy content:

Element	Min (%)	Max (%)	Role in WP316L
Carbon (C)	-	0.030	Prevents carbide precipitation
Chromium (Cr)	16.0	18.0	Corrosion/oxidation resistance
Nickel (Ni)	10.0	14.0	Austenite stability
Molybdenum (Mo)	2.0	3.0	Pitting resistance
Manganese (Mn)	-	2.00	Deoxidization
Silicon (Si)	-	1.00	Strength enhancement
Phosphorus (P)	-	0.045	-
Sulfur (S)	-	0.030	-

2. Equivalent Grades (Global Standard Cross-Reference)
