Typical Physical Properties of P92/ T92 Steel

The P92/ T92 seamless pipes or tubes manufactured to either ASME SA335 or ASME SA213 are widely applied in modern ultra-supercritical power plant units to improve heat efficiency. According to Metals-Piping’s engineering practice, it is most applicable to the steam-temperature of 580°C~600°C[1080°F~1110°F] and metal-temperature of 600°C~620°C[1110°F~1150°F]. The density of P92/ T92 steel is 7850 kgs/m3. The other main physical properties are listed below:
