When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials A709 grade 50W high strength steel. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
A299GrA steel plate is one of the materials widely used in boiler drums (steam drums) of coal-fired generator sets. Boiler plate A709 grade 50W high strength steel is mainly used in the head and shell of subcritical boiler drum products. Generally used for various welding parts whose working temperature does not exceed 400°C, such as boiler steam drums, pressure vessels, etc., which require the steel to have a high medium temperature.
A709 grade 50W high strength steel, P355GH plate mechanical properties: P355GH steel plate thickness/mm:> 60-100: tensile strength σb / MPa: 490-630; yield strength σx / MPa:> = 315 Impact absorption energy AKv / J:> = 34. Steel plate thickness / mm:> 100-150: tensile strength σb / MPa: 480-630,y ield strength σx / MPa:> = 295 Impact absorption energy AKv / J:> = 34. Chemical composition % (C:0.10-0.22, Si:<=03.60, Mn:1.00-1.70, Nb:<=0.010, Ti:<=0.03 S:<=0.030, P:<=0.025, Cr:<=0.30, Ni:<=0.30, Cu:<=0.30, Mo:<=0.10, V <=0.02)
The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality A709 grade 50W high strength steel products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
The high strength A709 grade 50W high strength steel low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of A709 grade 50W high strength steel ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
