该文介绍了16MnR和SM53—C两种球罐材料不同部位的常规断裂韧性测试,以及在H_2S水溶液和未脱硫液化石油气中的断裂韧性的测定,并对日本引进材料SM53—C作为球罐用钢16MnR代用材料的可行性进行了初步评价。
This paper introduces the conventional fracture toughness tests of different parts of 16MnR and SM53-C spherical tank materials, as well as the determination of the fracture toughness in H 2 S aqueous solution and non-desulfurized liquefied petroleum gas, and introduces the introduction of SM53-C as a spherical tank The feasibility of using steel 16MnR substitute material was preliminary evaluated.
