How to Avoid the Surface Decarburization - Permanent SteelThe atmosphere that causes decarburization on the surface of Q345B seamless steel tubes is mainly oxidizing gases such as oxygen, water vapor and carbon dioxide. When these oxidizing gases come into contact with the surface of the heated steel wire, oxidation and decarburization occur at the same time; due to the greater affinity of the solid solution carbon in the iron with these gases, the carbon on the surface of the Q345B seamless steel pipe
As we all know, China's steel production is the largest variety of rebar, followed by steel plate and sheet, and the largest percent of steel grade produced in the plate is Q235B, followed by Q345B. The biggest impact of the new GB/T 1591-2018 release is Q345B, because the output of other grades has little effect.
