GB/T 24186-2009 standard specifies high strength wear resistant steel plate for Engineering machinery. It specifies the grade and size of the steel plate, specifies the key technical requirements such as chemical composition and mechanical properties, and covers high strength and wear resistance performance indicators. At the same time, the standard gives corresponding test methods and inspection rules. Production enterprises produce according to this standard, which can ensure that the mass of the steel plate meets the standard. In the field of Engineering machinery, the steel plate is used to make easy abrasion parts. With its excellent performance, it can effectively extend the service life of the equipment and improve the Reliability of Engineering machinery under complex working conditions.
