SM490B plate is a kind of structural steel produced according to Japanese Standard JIS G3106. Min. tensile strength of SM490B plate is 490MPa. SM490B plate is mainly used in buildings, bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring high-level weldability. The delivery state is hot rolling for SM490B plate, A514 Gr P QT steel plate with thickness less than 80mm; and the delivery state is normalizing for SM490B steel plate with thickness more than 80mm.
With the development of China's A514 Gr P QT steel plate market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of A514 Gr P QT steel plate products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished A514 Gr P QT steel plate steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing A514 Gr P QT steel plate steel plate distribution services, so as to save customers manpower and material resources.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in A514 Gr P QT steel plate etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
The company is deeply supported and loved by customers with its unique business philosophy and business model. The company has always been adhering to the "credibility first, integrity-based, quality first" purpose, and sincerely serve new and old customers. Over the past twenty years, the company has won the trust of customers by relying on good service and good reputation.
