30CrMo gas cylinder steel pipe is used in metallurgy, machinery, shipbuilding, medicine and hygiene, scientific experiments, etc. With the development of science and technology, More and more people are using 30CrMo gas cylinder steel pipe, which will be of great use to the development of national economy and the people’s life.
30CrMo gas cylinder steel pipe has high strength, high toughness and good processability after heat treatment. 30CrMo gas cylinder steel pipe is one of the common materials used in the manufacture of high pressure gas cylinder tubes. The critical temperature of pearlite transformation in 30CrMo gas cylinder steel pipe is 693℃. The samples are heated to 870℃ for 50 min and then cooled to 680℃ for air cooling. The microstructure and mechanical properties of the samples after annealing are examined.
After normalizing the steel at 870℃ for 50 min, 90 min, the microstructure of the 30CrMo gas cylinder steel pipe is the main reason for the high strength and low elongation of the material when the microstructure of the 30CrMo gas cylinder steel pipe is integrated with the Behlich ferrite pearlite.
