ST52 Q345B 30CrMo 42CrMo4 Cold rolled bright seamless steel tube

Product Description

Cold rolled (drawn)seamless steel pipe:

Cold rolled seamless tube is a seamless steel tube for high dimensional accuracy and good surface finish.Cold rolled seamless pipe in addition to include the general steel,low and medium pressure boiler tube,high-pressure boiler tubes,alloy steel pipe,stainless steel pipe and oil cracking tube,also includes carbon thin wall steel pipe,alloy thin wall steel tube,thin-walled stainless steel pipe and special-shaped steel tube.The diameter of cold rolled seamless steel pipe is 6mm,wall thickness is 0.25mm,while the diameter of thin-walled tube can be 5mm,wall thickness can less than 0.25mm.The dimensional accuracy of cold rolling is higher than that of hot rolling.

Advantage of cold drawn seamless steel pipe:

Forming fast,high yield,and no damage to the coating,it can be made into a variety of cross sectional form to meet the needs of the use of conditions;Cold rolling can cause great plastic deformation,so as to improve the yield of the steel.

The technological process of cold-drawn(rolled) seamless steel tubes:

Tube blanks→Heating→Punching→Heading→Annealing→Pickling→Oil coating (copper plating)→Many times cold drawing (cold rolling)→ Blank tube→Heat treatment→Straightening→Hydrostatic test (flaw detection)→Marking→Warehouse.
