20Cr Precision Seamless Pipe

The 20Cr precision steel pipe supplied by GNEE has excellent properties such as high precision, high finish, high pressure and no leakage.

20Cr precision seamless pipe is a high-precision steel pipe material that has been processed by cold drawing or hot rolling. It is used to transport fluids, such as oil, natural gas, coal gas, water and some solid materials.

20Cr alloy pipe after carburizing treatment, the surface will form fine needle-shaped tempered martensite structure, the hardness can reach 58-62HRC, the core will form low-carbon martensite structure, the hardness is 35-40HRC, the matrix is strong and tough. After quenching and low-temperature tempering, this steel can obtain good comprehensive mechanical properties, good low-temperature impact toughness, and no obvious temper brittleness.
