12Cr1Mov large diameter seamless steel pipe

GB5310 (seamless steel pipe for high-pressure boiler) stipulates that steel pipes with an outer diameter greater than or equal to 76mm and a wall thickness of ≥ 14mm should be subjected to Charpy V-shaped longitudinal impact test at 20 °C; The average impact work of three specimens shall not be less than 40J, allowing the impact work of one specimen to be lower than the average but not less than 70% of the average. Steel pipes with an outer diameter of > 219.1mm and a wall thickness of ≥ 25mm can be tested instead of longitudinal mechanical properties test by transverse mechanical property test. Charpy V-shaped transverse impact test at 20 °C, large-diameter tube transverse mechanical property test is more convenient. The 12Cr1Mov Large Diameter Seamless Steel Pipe is a high-quality product designed specifically for use in industrial applications where strength, durability, and reliability are essential. Made from top-grade steel and designed with a large diameter, this…
