How can high precision be achieved during laser cutting of NV A40 passenger container ship steel

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, NV A40 passenger container ship steel quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the NV A40 passenger container ship steel International leading steel materials supplier.

S355N is a kind of weldable fine grain structural steel grade under EN10025-3 standard. It is often delivered in normalized or normalized rolled condition. There are various shapes available for NV A40 passenger container ship steel, S355N: steel plates, strip and steel sections. When producing this steel S355N plates, dimension, tolerances on thickness, width, length and shape shall be in accordance with the requirement given in the order by reference to the relevant documents according to EN10025-1 standard.

What are the general uses of NV A40 passenger container ship steel, low alloy steel plate? First, low alloy steel plate can be used as bridge steel plate, because it has strong bearing capacity. The bridge’s daily traffic flow is very large, so it must have very good bearing capacity. Second, because low alloy steel plate has good toughness and is easy to process, it is often used to manufacture ships and vehicles. Thirdly, the use of low alloy steel plate is indispensable to the construction of some frame structure workshops. Because of the low alloy content, low alloy steel plate has its own characteristics.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the NV A40 passenger container ship steel plate should be derusted before cutting.

EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are NV A40 passenger container ship steel, 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.

S355J2 hot rolled steel plate executive standard: EN10025-2S355J2 hot rolled steel plate delivery status: control binding, normalizing rolling, normalizingThe European standard S355J2 hot rolled steel plate is available from NV A40 passenger container ship steel stock and can be cut and processed according to the requirements of customers; the futures can be produced according to your requirements, and our S355J2 hot rolled steel plate price is preferential and the delivery time is fast, welcome to contact and purchase.
