Which steel pipes can be defined as low alloy steel pipes?

Among alloy steel pipes, when additions of alloys such as nickel, chromium and total molybdenum alloy content can range from 2.07% to levels immediately below those of stainless steel, containing a minimum of 10% Cr, they are defined as low-alloy steels.

• Chromium-molybdenum alloy steel pipe

This series of low alloy steel contains 0.5% to 9% Cr and 0.5% to 1% Mo. The average carbon content is less than 0.20%. The Cr content increases its anti-oxidation and anti-corrosion capabilities, and Mo increases its resistance under high temperature conditions; steel supply conditions are usually eliminated through annealing or standardization and tempering processes. Chromium-molybdenum alloy steel pipes have been widely used in the oil and gas industry, power plants and other high-temperature applications.
