Q345B Seamless Carbon Pipe,
16Mn Seamless Carbon Pipe,
Q345B/16Mn DIN17175 Seamless cold drawing Lower Alloy tube
Q345B is low alloy structural steel with good mechanical properties, low-temperature performance, plasticity and good weldability.
Q345B steel is a Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, and is used for a number of manufacturing purposes.
Q345B is material for steel pipes. Q represents the yield of this material, and the back 345 refers to the yield value of this material.
The Q345B steel pipe is a 16Mn steel pipe, which is one of the seamless steel pipe products. 16Mn is material in steel. A name for steel in the past. Now called the law: Q345B. 16Mn is a low-alloy steel series. In this series, it is the most common material or the grade of steel plate. The Q345B steel tube represents the carbon content of this steel in the range of about 0.16%. Mn alone was proposed because the five elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S) have high manganese content and are proposed separately. About 1.20-1.60%. Special treatment heat treatment: controlled rolling, normalizing, etc.Z-direction performance: Z15, Z25, Z35. Main features: good overall performance, good low-temperature performance, cold stamping performance, good welding performance and machinability
