GB/T 11251 20Cr hot rolled structure steel plates can also be used in quenching and tempering condition to manufacture parts with larger working speed and medium impact load. GB/T 11251 20Cr hot rolled structure steel plates can also be used as low-carbon steel for martensitic quenching, which further increases yield strength and tensile
GB/T 11251 20Cr hot rolled structure steel plates - Bebon GB/T 11251 20Cr hot rolled structure steel plates ,GB/T 11251 20Cr hot rolled structure steel plates are widely used to manufacture carburized parts (oil quenching) that have high requirements for core strength, bearing surface wear, section below 30mm, shape is complex and load is small. For example:machine transmission gear, gear shaft, cam, worm, piston pin, claw clutch.
GB/T 11251 40Cr hot rolled structure steel plates ,BBN GB/T 11251 40Cr hot rolled structure steel plate is one of the most widely used steel in the machinery manufacturing industry. After quenched and tempered, GB/T 11251 40Cr hot rolled structure steel has good and comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity.
