Q345R pressure vessel steel sheet Vs 301 Stainless Steel

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 Q345R pressure vessel steel sheet B2B platforms.

C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the Q345R pressure vessel steel sheet materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.
