Non - Corrosive Use Alloy Steel Tube , Cold Drawn Seamless Tube +QT 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 adjustment, use.
