概述
ASTM A213 specification covers seamless ferritic and austenitic steel boiler， superheater， and heat-exchanger tubes， designated Grades T5， T9， T11， T12， T22， T91， etc. Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements.
A213 T11 tube is often called chrome moly tube because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit， resistance to wear， impact qualities， and hardenability. Moly increases the resistance to softening， restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is the most effective single additive that increases high temperature creep strength. It also enhances the corrosion resistance of steel， and inhibits pitting. Chromium (or chrome) is the essential constituent of stainless steel. Any steel with 12% or more Chrome is considered stainless. Chrome is virtually irreplaceable in resisting oxidation at elevated temperatures. Chrome raises the tensile， yield， and hardness at room temperatures. The composition chrome moly alloy steel Pipe make it ideal for use in power plants， refineries， petro chemical plants， and oil field services where fluids and gases are transported at extremely high temperatures and pressures.
