Cangzhou Bohai Steel Tube Co., Ltd. specializes in elbow 16Mn steel is carbon steel, alloy steel elbow carbon content of about 0.16 percent offer, the yield point is equal to 343MPa (intensity level below 343MPa grade). Less alloy content 16Mn steel, alloy steel elbow weldability good sales, generally do not have warm-up before welding. However, due to the tendency of hardened steel 16Mn 15CrMo slightly larger than the low-carbon steel alloy steel elbow, so or welding at low temperature (such as winter outdoor work) on a large rigid, thick structure, in order to prevent the occurrence of cold cracking, the need to take Preheat measures.
