Q690D carbon steel plate sheet dimensions

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of Q690D carbon steel plate sheet steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special Q690D carbon steel plate sheet materials and specifications can be ordered in advance.

BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.

we also provide the Q690D carbon steel plate sheet welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful Q690D carbon steel plate sheet welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

BBN had provided Q690D carbon steel plate sheet Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our Q690D carbon steel plate sheet NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.

16Mo3 alloy are featured by the good heat resistance and corrosion resistance. 16Mo3 steel plate chemical composition(%):C: 0.12 ~ 0.2 Si: ≤0.35 Mn: 0.4 ~ 0.9 P: ≤0.025 S: ≤0.01 Cu: ≤0.3 Ni: ≤0.3 Cr: ≤0.3 Mo: 0.25 ~ 0.35 Al: ≥0.02 N: ≤0.012. 16Mo3 alloy steel mechanical properties:Yield strength (MPa) 372MPa, Tensile strength (MPa) 350MPa, Elongation (%) ≥22. Impact temperature (℃) 20, Impact energy value (J) 335J / cm². Q690D carbon steel plate sheet, 16Mo3 steel plate is widely used in petroleum, chemical, power station, boiler and other industries.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve Q690D carbon steel plate sheet work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
