EN steel grade S235JR material plain carbon steel

The common uses of EN steel grade S235JR material, boiler and pressure vessel steel plate are as follows. First, make boilers and pressure vessels. Boiler and pressure vessel steel plate not only has a certain strength, but also has a certain ability to withstand impact. The boiler and pressure vessel steel plate should be resistant to abrasion and high temperature. Second, the boiler and pressure vessel steel plate is used to make spherical tank, oil gas tank, liquefied gas tank and other tanks. The boiler and pressure vessel steel plate should have the characteristics of corrosion resistance and pressure resistance.

The company mainly supplies EN steel grade S235JR material steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of EN steel grade S235JR material steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.

EN steel grade S235JR material annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of EN steel grade S235JR material annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. EN steel grade S235JR material annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

EN steel grade S235JR material controlled rolling is that, on the basis of adjusting the chemical composition of EN steel grade S235JR material, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of EN steel grade S235JR material.
