CCS F32 hull steel plate, VL E460 steel plate is a kind of structural steel plate for ship and ocean engineering. "VL" stands for the abbreviation of "DNV-GL", which is a standard jointly certified by DNV (Norway) and GL (Germany), "E" means the grade of steel plate is E, and "460" means the min. yield of VL E460 steel plate is 460 Mpa. The delivery status of VL E460 steel plate: TM (thermo mechanical control rolling), QT (quenching + tempering), TM + T (thermo mechanical control rolling + tempering).
In order to improve the CCS F32 hull steel plate corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating.
Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
Vanadium mainly exists in the form of carbide in CCS F32 hull steel 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%.
