Product Description

A182 F5 F9 F11 F22 F91 F92 Alloy Steel Pipe Flanges

Chromium-Molybdenum Alloy Steel or Chrome-Moly, CrMo is an alloy steel intended for high temperature and high pressure services.  Chrome-Moly is used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength.  Chrome-Moly has a better strength to Weight ratio than steel, which enables designers to use thinner wall pipe or smaller diameter tubing to reduce overall weight.
Chromium-Molybdenum Alloy Steel has strong resistance to rupturing at high temperatures and high pressures.  Chrome-Moly is also resistant to cracking from hydrogen attack and hot sulfide corrosion cracking.
Chrome-Moly grades P11, P22, P91 and P92 are used in the power industry.  Chrome-Moly grades P5 and P9 are used in petro-chemical refinery processes.  Chrome-Moly Forged Fittings & Flanges are available in grades F5, F9, F11, F22, F91, F92.  Chrome-Moly Alloy Butt Weld Fittings are available in grades WP5, WP9, WP11, WP22, WP91, WP92. F11 and F22 material meet NACE-MRO 175. 
Available sizes from 1/2" to 120" or custom, working pressures in 150#, 300#, 400#, 600#, 900#, 100#, 2500#
