A709 grade 50W structural steel sheet, A335 P22 is a steel grade of American Standard boiler tube, and the executive standard is ASTM A335 / A335M, which is chromium molybdenum high temperature ferritic steel for boiler and superheater. A335P22 alloy pipe is mainly used as heating surface pipe of low and medium pressure boiler (working pressure is generally not more than 5.88 MPA, working temperature is below 450℃); A335P22 alloy pipe is also used as economizer, superheater, reheater and petrochemical industry pipe of high pressure boiler (working pressure is generally above 9.8MPa and working temperature is between 450℃ and 650℃).
The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate A709 grade 50W structural steel sheet should also have good welding performance and low notch sensitivity. If you want to have a more comprehensive and detailed understanding of bridge steel plate, welcome to visit our official website for consultation.
A709 grade 50W structural steel sheet, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.
