Manufacturing Method:Steel should be manufactured in electric or oxygen converter.Steel Pipe should be manufactured by cold drawn seamless method.
Delivery State:After final cold drawn,steel tubes will be deliveried with heat treatment.
Test Item:Tensile test ,Cold head forging, test Hydraulic test, Eddy current test
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.
Main Application:
to be used in hydraulic system, automobile parts and in the occasion where the high precision, brightness, cleanness and mechanical properties of the tube are required.
