16Mn seamless steel pipe and 16MnR, 19Mng were combined into Q345R. Q345R is an ordinary low-alloy steel, which is commonly used in boiler pressure vessels. The delivery status is divided into hot-rolled or normalized steel, which is a low-alloy steel with low Mn content. The performance is similar to 20G (412-540), the tensile strength is slightly stronger (450-655), the elongation is 19-21%, and is worse than the 24% of 20G. Q345R process reference standard GB713-2008.
