On the chemical composition of Wuxi 16mn seamless, 16Mn and Q345 are not the same. More importantly, the presence of the thickness of the packet size according to the yield strength of the two different steels carried big difference 16mn, which will cause some promise with changes in thickness of material stress. So 16mn thick-walled seamless steel pipe, simply allowable stress applied on 16Mn steel Q345 steel is inappropriate, and should be re-determined allowable stress Katherine source Pipe Co., Ltd. Liaocheng supply 16Mn steel thickness according to the new packet sizes The chemical composition of seamless steel mechanical properties of steel 8876839,16Mn telephone area code 0635: C: 0.12 ~ 0.20; Mn: 1.20 ~ 1.60; Si: 0.20 ~ 0.55; tensile strength: 470 to 660 N / mm2; yield strength: 275 to 345 N / mm2; elongation: 21%. Specific values ??according to the thickness or diameter of steel, 16mn, Zhangzhou 16mn, Katherine source of steel provided by source Pipe Co., Ltd. Liaocheng trillion.
