This is the second year we have been golden supplier on Alibaba. Over the decades, we have accumunited rich customer resources and have established stable copperation with many customers all over the world. So we did not reply on a573 grade 70 and sa709 grade 50 steel comparison B2B platforms. But with the development of the company and the increasing of the company reputation, it is necessery for us to open up more channels for customers to reach us.
Temperature has a great influence on the strength of the material, a573 grade 70 and sa709 grade 50 steel comparison. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
The difference between a573 grade 70 and sa709 grade 50 steel comparison, 10# seamless steel pipe and 20# seamless steel pipe: 1. Chemical composition Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25 2. Mechanical properties 10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
