(PDF) Effect of Post Weld Heat Treatment on Impact

The purpose of the current study is to provide detailed information on the effect of PWHT on the microstructure and mechanical properties of a ASME SA 516 Gr. 70 preassure vessel steel joint. The A516 and A387 Pressure Vessel Steels:A Technical Figures 7-9 further summarize the results of testing on 1-1/2 and 3 inch thick A516 Grade 70 plate and show the degradation of toughness as PWHT severity increases. Figure 7 depicts the actual absorbed energy values but a more dramatic representation of the data is illustrated in Figure 8. In this example, toughness at 50ºF

Carbon Plate- ASTM A 516. Standard specification for Pressure Vessel Plates. Carbon Steel, for Moderate and Lower Tempeature Service. First issued in 1964. This specification covers carbon steel plates intended primarily for use in welded pressure vessels where improved notch toughness is important. It allows for four different strength levels. The most common is Grade 70.
