Research and Production of V-Cu-Ni Series High Strength Steel for Pressure Vessel
Abstract:
To manufacture the large ball oxygen tank, a kind of thick V-Cu-Ni series steel plates and forging kits with minimum yield strength of 460MPa have been researched and produced. The test steel plates have an obvious characteristic of aging strengthening and toughening effect after being normalized and tempered. The cryogenic toughness of the steel plates appears excellent. The mechanical properties can meet with the technical requirements ofP460NLl in the standard of DIN EN 10028-1992. Six ball oxygen tanks with the volumeof 650m3each have been made in Bao Steel using this kind of steel plates and forging kits and have been in safe operation for 4 years.
