What is the EN steel grade S275J2 material pipe schedule

The company adopts the EN steel grade S275J2 material international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety EN steel grade S275J2 material management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

Bearing steel is a kind of steel used to manufacture rolling bearings such as balls and rollers, and even sleeves. It can also be used to manufacture precision measuring tools and coupling parts. The physical properties of its bearing steels are very good. Generally speaking, they are made by heat If rolled annealing and cold drawing annealing are used for delivery, the delivery status should be specified in the contract.

20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for EN steel grade S275J2 material steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.

Oxygen (O) is a harmful element in steel such as EN steel grade S275J2 material. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

A537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the EN steel grade S275J2 material, A537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of A537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.
