BBNsteel is a world-leading corrosion-resistant steel supplier, with a global reach stemming from our secure chain of high-quality steel mills across China. We offer both Q235R, Q345R and A709 grade 50W high strength steel, alongside a catalogue of stainless steel grades for various industries. If you would like to learn more, simply contact our online staff.
A517 Grade Q steel is a low-alloy pressure vessel grade rolled steel plate that conforms to A20 manufacturing specifications; in an open-hearth under oxygen or via electric arc production. These plates have a maximum thickness of 32mm A709 grade 50W high strength steel and must be subjected to robust heat analysis to verify its elemental composition. Process managers must carefully control the levels of carbon, manganese, phosphorous, sulfur, silicon, chromium, molybdenum, boron, vanadium, and titanium in order to guarantee compliance – thus performance.
The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, A709 grade 50W high strength steel. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
Vanadium mainly exists in the form of carbide in A709 grade 50W high strength 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%.
The hardness of A709 grade 50W high strength steel, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide A709 grade 50W high strength steel cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about A709 grade 50W high strength steel ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.
Our company will accept the product quality objection registration record, pass it to the A709 grade 50W high strength steel production unit and relevant departments, and timely coordinate the supervision of product A709 grade 50W high strength steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
