Welcome to BBN High Strength Steels Factory
The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.
Q370q steel is a kind of bridge steel plate. It is delivered in hot rolled, normalized condition. There are three quality levels Q370qC, Q370qD, and Q370qE. Bridge steel Q370qC, Q370qD, material S620QL and Q370qE steel plates have different impact temperatures: C represents 0℃, D represents -20 ℃, and E represents -40℃. Q370qC-Z25 steel plate can be hot-rolled and normalized heat-treated. When mechanical properties are required, large thickness must be normalized. The thickness of Q370q steel plate we supply is above 8mm.
As for Q460 series low alloy steel, there are three quality Grade C, D, E. material S620QL, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.
As a new type of coil material, compared with the traditional steel coil, material S620QL, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel material S620QL plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide material S620QL cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about material S620QL 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.
