Hot selling Manufacturers Direct Sales of High Precision Cold Rolling 20Cr Precision Seamless Steel Pipe Precision Tube
Short Description:
20Cr alloy steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling treatment. Because the inner and outer walls of precision steel pipes have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation during cold bending, flaring, flattening and no cracks, etc., 20cr precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemical, electric power, ships, aerospace, bearings, and pneumatic components.
