Shipbuilding steel plates are used to manufacture marine and inland ship hulls, which require high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. BBN steel company produces various grades steel plates for shipbuilding like AH32, AH36, AH40, DH32, DH36, EH32, EH36, RINA FH40 high tensile steel plate and can produce marine steel plates and sheets with different certificates according to client needs.
In March, the daily output of key iron and steel enterprises decreased on a month on month basis. In terms of enterprise inventory, in late March, the key statistics showed that the RINA FH40 high tensile steel plate steel inventory of iron and steel enterprises was 18.067 million tons, a decrease of 3.342 million tons or 15.6% compared with the highest inventory in early March, and an increase of 8.534 million tons or 89.5% compared with the beginning of the year.
Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe, RINA FH40 high tensile steel plate. Seamless pipe supply scope is OD 10.3mm--965.2mm, wall thickness 1.0mm--60mm. The ERW pipes production range from OD 21.3mm--660mm, wall thickness 1.0mm--16mm. LSAW pipes can supply with OD 406mm--1524mm, wall thickness 6mm--50mm. SSAW pipes can produce maximum OD 3500mm, minimum OD 219.1mm, wall thickness 3.2--25.4mm.
Vanadium mainly exists in the form of carbide in RINA FH40 high tensile 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%.
