Yield Strengths of ASTM A204 Plates for Elevated Temperatures

August 28, 2020

The Table Y-1 of ASME BPVC Section II Part D has provided yield strength values for the three steel grades of ASTM A204 for various elevated temperatures. Similar to the tensile strength values, these values are only used for design calculation purpose.
