A709 Gr HPS50W bridge steel plate,Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, , the impact toughness is also required.
Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. , Q420 steel has high comprehensive mechanical properties Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states The quality grades are C, D, E Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load,A709 Gr HPS50W bridge steel plate.
A709 Gr HPS50W bridge steel plate,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 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 steel plate.
