Product Description

F1 F5 F9 F11 F12 F91 Alloy Steel 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
