2020 new price of EN steel grade S355J2 material

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, EN steel grade S355J2 material, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, EN steel grade S355J2 material seamless steel pipes for ships and petroleum cracking EN steel grade S355J2 material steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many EN steel grade S355J2 material products have been exported to the Middle East, India, Southeast Asia and Europe and America.

In actual processing applications, the processing EN steel grade S355J2 material thickness of flame cutting ranges from 6 to 200 mm, and the EN steel grade S355J2 material cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting EN steel grade S355J2 material with a certain thickness above 10mm.

The effect of alloy elements of EN steel grade S355J2 material, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.

Our company will accept the product quality objection registration record, pass it to the EN steel grade S355J2 material production unit and relevant departments, and timely coordinate the supervision of product EN steel grade S355J2 material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
