Different names of equivalent material of nm500 steel

The grades specified in the GB712-2011 ship and marine engineering structural steel standard are: Grade A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, AH420, equivalent material of NM500 steel, DH420, EH420, FH420, AH460, DH460, EH460, FH460, AH500, DH500, EH500, FH500, AH550, DH550, EH550, FH550, AH620, DH620, EH620, FH620, AH690, DH690, EH690, FH690.

Pickled steel coils are processed by pickling machines to remove the oxide layer. Because of the deoxidation treatment, certain characteristics of the pickled steel coils are more prominent. First, the surface is smoother and exquisite. For products that require the appearance of the steel plates, pickling steel coil is a good choice. Second, the surface of the pickled steel coil is smooth and not easy to oxidize, and it is convenient and quick to paint. Third, equivalent material of NM500 steel, pickled steel coils have high precision.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image equivalent material of NM500 steel processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the equivalent material of NM500 steel steel plate.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, equivalent material of NM500 steel and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
