EN steel grade S235J0 material sheet

15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of EN steel grade S235J0 material and 15CrMo alloy plate is obvious and the weldability is poor. After welding, local high temperature tempering treatment should be carried out. The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling.

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as EN steel grade S235J0 material, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. EN steel grade S235J0 material Heat treatment process refers to the ability to change the microstructure and properties of EN steel grade S235J0 material after heat treatment, including hardenability, hardenability, temper brittleness, etc.
