Quenched and tempered GL-E40 hull steel plate,Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, based on a high starting point and high technology, the company has vigorously developed various steel products quenched and tempered GL-E40 hull steel plate and deep-processed parts, steel structures, precision castings, seamless pipes.
We are mainly engaged in corrosion-resistant steel materials and steel processing parts, the varieties include Q355NHB, Q345NS, 09CuPCrNi-A,coten-A/B,S355J0W, Q345qNHB The application fields involve landscape gardening, outdoor structure, environmental protection equipment, railway carriage, bridge manufacturing and many other industries The company currently has many steel extension processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment,quenched and tempered GL-E40 hull steel plate.
Quenched and tempered GL-E40 hull steel plate,Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from quenched and tempered GL-E40 hull steel plate. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.
Quenched and tempered GL-E40 hull steel plate,we also provide the 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 welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.quenched and tempered GL-E40 hull steel plate
StE 480.7 TM steel plate/pipes,under DIN 17172 standard, we can regard StE 480.7 TM steel plate/pipes as large diameter pipes. StE 480.7 TM steel plate/pipes is one mainly of Steel for large diameter pipes,DIN 17172 StE 480.7 TM steel with the demands in mechanical properties of the pipes followed the DIN 17172 specification for grade StE 480.7 TM(YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
