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.

20Cr alloy steel pipe can improve the material utilization rate, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sleeves, etc. 20Cr alloy steel pipe is also an indispensable material for various conventional weapons, and the barrel and barrel of the gun are made of steel pipe.

1. Incoming Raw Material Inspection 2. Raw Material Segregation to avoid steel grade mix-up 3. Heating and Hammering End for Cold Drawing 4. Cold Drawing or Cold Rolling, On line inspection 5. Heat Treatment 6. Straightening/Cutting to specified length/Finished Measuring Inspection 7. Quality Testing in own lab with Tensile Strength, Yield Strength, Elongation, Hardness, Straightness, etc. 8. Packing and Stocking. 100% Eddy Current Testing. 100% Size Tolerance Checking. 100% Tube surface checking to avoid surface defects
