1. Introduction to S235J0 steel plate material:
S235J0 steel plate is a common low-alloy high-strength structural steel, and its chemical composition and mechanical properties are specified in the European standard EN 10025-2. @@185 9190@@这种钢板广泛应用于桥梁, construction, shipbuilding, vehicle and machinery manufacturing and other fields, due to its excellent mechanical properties and machinability, it has become an important engineering material. S235 is a common carbon structural steel plate belonging to the European standard, and the implementation standard is the European standard EN10025 standard, which has three grades: S235JR, S235J0 and S235J2.
2. Description of the same series of S235J0 steel plates.
The difference between S235JR, S235J0 and S235J2 is the difference in impact temperature, JR stands for room temperature impact, J0 stands for 0 impact, J2 stands for -20 impact, except for the difference in impact temperature, there is no other difference.
