GB/T 36586.2 - 2018 is the second part of the standard for die wear-resistant plates, focusing on B-type wear-resistant plates. It specifies the size specifications of B-type wear-resistant plates in detail, including key parameters such as length, width, thickness, etc., to ensure that the product size is accurate and uniform. Clear material performance requirements, such as Hardness, abrasion resistance and other indicators, to ensure that it can effectively resist abrasion during die work. Appearance mass is also standardized, and surface defects are strictly controlled. This standard provides the basis for die manufacturers to manufacture B-type wear-resistant plates, helping to improve the overall performance of the die, extend the service life, and meet the mass demand for wear-resistant plates in the stamping processing industry.
