ASTM A106 GradeC Q345 16Mn Hot Rolled/ Cold Rolled Boiler Steel Tube
Product Description
16Mn steel belongs to carbon manganese steel, the content of carbon is about 0.16%, the yield point is equal to 343MPa (strength grade belongs to 343MPa grade). 16Mn steel has less alloy content and good weldability. It is generally not necessary to preheat before welding. However, because the hardening tendency of 16Mn steel is slightly greater than that of low carbon steel, it is necessary to take preheating measures to prevent cold cracks when welding at low temperature (such as open-air operation in winter) or on structures with large rigidity and thickness.
