EN10305-1 Precision Seamless Steel Tubes E235 E355 Steel Round Pipe For Automotive Part
Description
Precision seamless steel pipe is a kind of high precision steel pipe after cold rolling or cold drawing. Full name: cold rolling precision seamless steel tube. Because of the precision seamless steel tube inside and outside wall has no oxide layer, under high pressure, no leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks, etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, are made with seamless tube.
Delivery Condition
BKS(+SR): After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere.
NBK(+N): After the final cold drawing operation the tubes are normalized in a controlled atmosphere.
GBK(+A): After the final cold drawing process the tubes are annealed in a controlled atmosphere.
BK(+C): No heat treatment after the final cold drawig process.
BKW(+LC): After the final heat treatment there is a suitable drawing pass.
