Material Reference
Grades We Stock and Supply
The material grade decides what the flange can do. Pressure, temperature, corrosion resistance, sour service, and low-temperature toughness all flow from the chemistry and the heat treatment. Domestic-melt availability covers the major grades.
Carbon Steel
A105, A350 LF2 and LF3, A516-70, A36, A694 F42 through F70. The default material family for industrial pressure service.
Stainless Steel
F304, F304L, F316, F316L, F321, F347, plus dual-certified options. Corrosion resistance and food and chemical service.
Alloy Steel
Chrome-moly F11, F22, F91, F92 for elevated temperature and creep service. A350 LF3 for low-temperature carbon-nickel.
Exotic Alloys
Duplex 2205, super duplex 2507, Inconel 625 and 825, Hastelloy C-276, Monel 400, titanium grade 2. Corrosive duty and specialty service.
