In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel A572 grade 55 high strength steel surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
The increase in China's A572 grade 55 high strength steel and so on steel production will provide strong support for iron ore prices in the second quarter. According to the latest Outlook Survey of S&P Global Platts, despite the slow recovery of downstream steel demand, iron ore prices should be strongly supported in the second quarter as Chinese steel mills are expected to increase steel production.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in A572 grade 55 high strength steel 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.
