For A514 grade B quenched and tempered steel buyers, the impact of the rise and fall of A514 grade B quenched and tempered steel prices is great. Because of the large amount of A514 grade B quenched and tempered steel purchases and the large amount of funds involved, many A514 grade B quenched and tempered steel purchasers will carefully consider the price issue, and some A514 grade B quenched and tempered steel purchasers who are far away will also consider the freight issue. When the price of A514 grade B quenched and tempered steel overall drops, a large number of A514 grade B quenched and tempered steel buyers will hoard in large quantities. When A514 grade B quenched and tempered steel prices rise, we should predict and stock up appropriately.
The SM570 steel plate has a yield strength of more than 460MPa and a 60Kg strength grade steel because it contains a variety of alloying elements, including microalloying elements, and can often achieve higher strength in the state of hot rolling or controlled rolling, but the impact toughness fluctuates greatly. A514 grade B quenched and tempered steel product Normalizing has the advantages of uniform and stable steel structure and performance, high qualification rate, and easy control of the production process.
Vanadium mainly exists in the form of carbide in A514 grade B quenched and tempered steel and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
Nickel element is mainly used to form and stabilize the austenite structure, so that the A514 grade B quenched and tempered steel steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
