Synopsis or Process Routing:quality carbon steel-cold drawing-bright heat treatment without oxidization (NBK status)--nondestructive testing. In the wall honing and inside flushing under the high pressure--plastic capping on both ends--Phosphating- Antirust oiling outside surface-Bundles

 

Main Features:high accuracy,excellent brightness.no oxidization on the outer and inner walls after heat treatment,high cleanness inside wall. The steel tube is able to stand high pressure.No deformation after cold bending, no crack after flaring and flattening. The complicated geometrical forming and machining can be realized. bright black. Color is homogeneously distributed on the tube surface. The tube has good property of antirust

 

Main Application:to be used in hydraulic system,automobile and in the occasion where the high precision.brightness, cleanne-ss and mechanical properties of the tube are required.

 

Main grades:ST35,ST37,ST37.4,ST45,ST52,E235,E255,E355,etc

Delivery Status:Nbk(+N)+Black Phosphating

Specifications:OD:4MM-76MM,WT:0.5MM-8MM
