SPV490 pressure vessel steel plate Chemical composition

The chemical composition of SPV490 boiler steel plate mainly includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S). The specific contents are as follows:

SPV490 pressure vessel steel plate Mechanical Properties

The yield strength of SPV490 pressure vessel steel plate reaches more than 490MPa. This high yield strength indicates that when subjected to external force, the steel plate can maintain elastic deformation before reaching this stress value. Once the yield strength is exceeded, plastic deformation will occur.
