It is understood that wear-resistant plate is a product type with relatively bright brightness in wear-resistant steel plate. A131 FH40 ship construction steel, The wear-resistant plate has large hardness and is widely used. It can be applied in most of the engineering and mechanical industries. The performance of wear-resistant plate is good, and the direct reason for its wide use is that the density is relatively large.
Hydrogen (H) is the most harmful element in general steel such as A131 FH40 ship construction steel. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
In steel standard JIS G3106, SM570 steel owned the highest yield strength above 460 Mpa, and the tensile strength within 570-720 Mpa. For SM570 steel, the C element content is 0.18%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.035% max, the S element content is 0.035% max. A131 FH40 ship construction steel, SM570 steel with thickness from 6mm-300mm,width from 1500mm-4000mm,length from 5000-16000mm.
The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the A131 FH40 ship construction steel, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
