T11,T12 Alloy Steel Pipe Feature
T12 alloy tube has the characteristics of large thermal
conductivity, small expansion coefficient, good oxidation
resistance, and excellent stress corrosion resistance. It is mostly
used in the manufacture of atmospheric resistance, corrosion
resistance, high temperature resistance and other projects. T12
alloy pipe is based on high-quality carbon structural steel pipe by
adding one or several alloying elements to improve the mechanical
properties, toughness and hardenability of steel. The production of
T12 alloy pipe usually requires heat treatment, normalizing or
quenching and tempering. Before use, it usually needs to undergo
quenching and tempering or surface chemical treatment, carburizing,
nitriding surface quenching or high frequency quenching, etc.
Application
Petroleum, chemical, electric power, boiler and other industries.
