SM570 steel material equivalent jis material

In today's SM570 steel material steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of SM570 steel material market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. SM570 steel material, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.

Special boiler steel is derived from carbon structural steel, SM570 steel material. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

The company has passed ISO quality management system certification, domestic advanced production technology, and high product batch stability. Selected materials, the source controls every quality link to ensure SM570 steel material product high quality. Use automated, scientific and systematic manufacturing processes to meet the different needs of customers. Become an excellent domestic steel plate manufacturer, serving customers all over the world.

GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. SM570 steel material, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.

Our company will accept the product quality objection registration record, pass it to the SM570 steel material production unit and relevant departments, and timely coordinate the supervision of product SM570 steel material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
