gbt 11251 12cr2ni4 steel property

Effect of heat treatment process on impact properties of

In order to study the hardness and impact properties of GBT 11251 30CrMnSi steel with different quenching processes, two heat treatment processes were selected to study. First process is the conventional quenching process, the quenching temperature is 910 , tempering temperature according to 230, 330, 430, 530 and 430 . 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.
