BBN EN steel grade S460ML material break through thickness limit

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the EN steel grade S460ML material quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After EN steel grade S460ML material quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

This is the second year we have been golden supplier on Alibaba. Over the decades, we have accumunited rich customer resources and have established stable copperation with many customers all over the world. So we did not reply on EN steel grade S460ML material B2B platforms. But with the development of the company and the increasing of the company reputation, it is necessery for us to open up more channels for customers to reach us.
