What is the difference between 42CrMo4, 50CrMo4, 51CrV4 steel online supplier and medium plate
Main properties of 20CrMn steel plate: high strength and toughness, and good hardenability. The performance obtained after heat treatment is better than 20Cr. The quenching deformation is small, the low temperature toughness is good, and the machinability is good; but the welding performance is low. Generally used after carburizing, quenching or quenching and tempering. 20CrMn steel is used for manufacturing and heavy-duty hardened and tempered parts with large cross section and carburized parts with small cross section.
Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, 42CrMo4, 50CrMo4, 51CrV4 steel online supplier included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
Lopes, President of the Brazilian Iron and Steel Association, pointed out that at present, increasing 42CrMo4, 50CrMo4, 51CrV4 steel online supplier and so on steel exports would be the best choice for Brazilian steel producers. The Association has made a series of proposals to the Brazilian government to support the economic recovery. Lopes revealed that the Association is seeking to increase the export tax rebate proportion of the steel industry from the current 0.1% to 5%, which will give related products a price advantage of 7% when exporting, and the export volume is expected to increase by 20%.
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 42CrMo4, 50CrMo4, 51CrV4 steel online supplier 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 42CrMo4, 50CrMo4, 51CrV4 steel online supplier steel plate.
