Performance processing of small diameter precision seamless steel pipe
1. The original state of steel, that is, the delivery state of steel pipes, can be divided into (codes in brackets): cold working/hard (BK), cold working/soft (BKW), stress relief annealing after cold working (BKS), tempering (GBK) ), normalizing (NBK). The commonly used state is the annealed sta...Read more -
Why does quenched steel need to be tempered
The main reasons for tempering quenched steel are as follows: 1. Eliminate internal stress: During the quenching process, large internal stress will be generated inside the steel parts. If not handled in time, internal stress will cause further deformation or even cracking of the workpiece. Tempe...Read more -
