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, BV grade D refrigerated cargo ship steel based on a high starting point and high technology, the company has vigorously developed various steel products BV grade D refrigerated cargo ship steel and deep-processed parts, steel structures, precision castings, seamless pipes.
SAPH series steel plates for automobile structures have good stamping and forming properties, and are used to make automobile beams, wheels and other structural parts. Hot rolled high yield strength steel for cold forming has high strength and good cold formability, and is used to make structural parts such as automobile beams. BV grade D refrigerated cargo ship steel, The steel for automobile girder has good stamping forming performance, and is used for manufacturing structural members such as longitudinal beams and transverse beams of automobile frames.
Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, BV grade D refrigerated cargo ship steel are strict. In the chemical composition of boiler steel, BV grade D refrigerated cargo ship steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished BV grade D refrigerated cargo ship steel steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing BV grade D refrigerated cargo ship steel steel plate distribution services, so as to save customers manpower and material resources.
