Research on the Field Identification Method of Q355 Steel in Petrochemical Projects
In the construction of petrochemical plants,the misuse and mixing of Q355 low-alloy high-strength structural steel and Q235 carbon structural steel will greatly reduce the main structural bearing capacity of the building and seriously compromise the intrinsic safety of the project.The Mn content,hardness and tensile strength of the two steels were analyzed,and a method for easily identifying Q235 and Q355 steels is presented,which provides a simple and operable basis for identifying the material of steel structures in the field.
