ASTM Corten B steel is a hot-rolled structural steel product with better atmospheric corrosion resistance under Technical delivery conditions. ASTM Corten B steel conforms to ASTM standard, with yield strength of 355MPa and 345mpa, and the ABS grade A monohull steel yield strength depends on the thickness. The tensile strength of ASTM Corten B steel is 470-630 MPa.
The wear-resistant layer of ABS grade A monohull steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy ABS grade A monohull steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
Non-destructive flaw detection of steel plates is a test method for inspecting the ABS grade A monohull steel surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used ABS grade A monohull steel steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
