Alloy Steel Tube Non-Corrosive Use Pipe Manufacture Seamless Bare
Surface 30ΧΓСΑ / 30CrMnSiA
The main features
High strength adjustable structural steel. It has high strength and
toughness, high hardenability, medium cold deformation and good
cutting performance. There is a tendency of temper brittleness, and
the transverse impact toughness is poor. Welding performance is
good, but the thickness is greater than 3 mm, should be preheated
to 150 ℃, need to heat treatment after welding. After general
Chemical composition (%)
30ΧΓСΑ / 30CrMnSiA
It is used to make parts that are wear-resistant, low temperature,
and variable load, such as the vane, valve plate and non-corrosive
pipe of the high pressure blower.
