A517 Grade Q steel is a low-alloy pressure vessel grade rolled steel plate that conforms to A20 manufacturing specifications; in an open-hearth under oxygen or via electric arc production. These plates have a maximum thickness of 32mm asme SA709 Grade 50 low alloy steel plate and must be subjected to robust heat analysis to verify its elemental composition. Process managers must carefully control the levels of carbon, manganese, phosphorous, sulfur, silicon, chromium, molybdenum, boron, vanadium, and titanium in order to guarantee compliance – thus performance.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. asme SA709 Grade 50 low alloy steel plate, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
