16Mn / Q345B is a steel pipe material. Q represents the yield of this material, behind the 345 refers to the yield value of this material. Q345B 16Mn steel is steel pipe, seamless steel pipe products in the category. 16Mn / Q345B steel as the kind of material. The last one is called steel. The law now says: Q345B. 16, as represented by the carbon content of this steel is about 0.16%. The Mn singled 16mn, because the five elements (carbon C 16mn thick-walled seamless steel tubes, silicon Si, manganese Mn, phosphorus P, sulfur S), the content of manganese is high, it singled out. Of about 1.20-1.60%. 16Mn / Q345B is a low-alloy steel plate series, in this series, the most common material, or grades of steel. According to the special requirements of Wuxi 16mn seamless steel pipe, steel plate can be some special treatment: heat treatment and Z to the performance. Katherine source Pipe Co., Ltd.
