Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, ASTM A573 plate. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.
The technical conditions are applicable to the high-strength A514Gr. Q alloy steel plate with thickness of 80-152mm. ASTM A573 plate, A514Gr. Q high yield Strength Quenched and tempered alloy steel plate suitable for the rack of construction machinery and jack up offshore drilling platform. Available steel plate specifications range: thickness 8-650mm, width 1500-4020mm, length 4000mm-17000mm. Our company can supply alloy steel plates every month 500tons.
In production and operation, the company always attaches great importance to product ASTM A573 plate quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market ASTM A573 plate. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in ASTM A573 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.
