Welcome to BBN High Strength Steels Factory
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 S690QL square pipe. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
BBN steel have large stock of hot rolled plate S690QL square pipe. Our products are exported to many countries: South Africa, France, Zimbabwe, Egypt, Mexico, Pakistan, Azerbaijan, Trinidad & Tobago,Tunisia, Chile, Angola, Belarus, Sri Lanka, Afghanistan, Turkey, Hong Kong, United States, Bahrain, Brazil, Jordan, Czech Republic, Indonesia, Denmark, Canada, Taiwan, Iran, Tibet, Nigeria, Croatia, Kazakhstan, Poland, Iraq, Yemen, Bolivia, Serbia, Finland, Nepal, Morocco, Ireland, Singapore, Italy, New Zealand, Namibia, Saudi Arabia, Mexico, Qatar, Lebanon, South Korea.
The purpose of S690QL square pipe quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of S690QL square pipe. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.The EN10113 S275M steel is equivalent to DIN StE285TM,UNI FeE275KGTM. EN10113 S275M steel plate/sheet,EN10113 S275M steel plate/sheet, under EN standard, we can regard S690QL square pipe, S275M steel plate/sheet for Fine-grain structural steels, thermomechanically rolled steel.
Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For S690QL square pipe ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the S690QL square pipe standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
