As a leading hot rolled plate mill in China, We manufacture and export carbon steel and alloy NV D40 hull steel material steel plates in different sizes and of different thickness. We have an adept and proficient team of professionals in addition to our responsive staff that is ever alert for any customer queries and requisites. If you are experiencing difficulty in selecting the correct NV D40 hull steel material steel plates for your business, we have a team of experts who can give you the best advice on steel plates, a significant contributor that can flourish your business.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's NV D40 hull steel material steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole NV D40 hull steel material steel transportation industry.
In actual processing applications, the processing NV D40 hull steel material thickness of flame cutting ranges from 6 to 200 mm, and the NV D40 hull steel material cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting NV D40 hull steel material with a certain thickness above 10mm.
In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.
EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are NV D40 hull steel material, S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.
