The measure of CCS grade D hull shipbuilding plate steel structural

Vanadium mainly exists in the form of carbide in CCS grade D hull shipbuilding plate and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of CCS grade D hull shipbuilding plate high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Bebon Iron and Steel's 4300 mm rolling mill, 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's CCS grade D hull shipbuilding plate technical equipment.

According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn CCS grade D hull shipbuilding plate seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black CCS grade D hull shipbuilding plate line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.
