Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This BV EH32 floating vessel steel method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
In February, the European steel price index was 161.2 points, up 1.3 points on a month on month basis, up 0.8%; the euro zone manufacturing PMI was 49.2%, up 1.3 percentage points on a month on month basis. The manufacturing PMI of Germany, Italy, France and Spain were 48%, 48.7%, 49.8% and 50.4% respectively. This month, among the main steel products such as BV EH32 floating vessel steel in the German market, the price of wire rod decreased slightly, the price of section steel remained stable, and other products continued to rise.

GB711-2011 Chinese steel standard is used in the manufacture of steel plates with a BV EH32 floating vessel steel thickness of not more than 150mm for navigating ships, fishing boats and marine engineering structures in ocean, coastal and inland waterway areas. CCS/NV/GL550 steel is a structural steel for ships and marine engineering, divided into four quality grades A, D, E, F, namely AH550, DH550, EH550, FH550, H is high-strength building materials, and 550 is the lower yield strength.
