S355J2W structural steel carbon steel hr plates 2020.09.14

S355J2W structural steel,The strength indexes of pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the S355J2W structural steel material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.
The company attaches great importance to systematic management, and has passed the ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification Insist on quality and promote brand development The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%,S355J2W structural steel.
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 S355J2W structural steel 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,S355J2W structural steel.Compared with the common pressure vessel, the pressure parts of the boiler not only bear the pressure, but also suffer from the radiation and erosion of the high temperature flue gas. Once the pressure components of the boiler fail in operation, it will cause extremely serious consequences. Therefore, the steel materials used to manufacture the pressure components of the boiler must have enough high strength, plasticity, toughness, fatigue resistance and corrosion resistance, as well as good high-temperature mechanical properties for high-temperature components.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
