How To Choose High Quality 42CrMo Seamless Pipe
2021-11-18 10:40:36

The national standards for precision steel pipes are GB/T699-2008, GB/T3639-2008, and GB/T8162-2008.

European standard for precision steel pipe: DIN2391

Basic use

Precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless steel pipes for medium and low pressure boilers, etc., and can also be applied to steel sleeves, bearings, hydraulics, machining and other fields !

Production Process

The production process of precision steel pipes is the same as that of ordinary seamless pipes, except for the final pickling and cold rolling process.

The precision steel pipe has high dimensional accuracy and smooth inner and outer surface. After heat treatment, there is no oxide film on the inner and outer surfaces of the steel pipe. The steel pipe is flared and flattened without cracks, cold-formed without deformation, and can withstand high pressure, and can be subjected to various complex deformations and deep mechanical processing.
