It is well known that the hardness of tungsten carbide is much higher than that of ordinary metals, and high hardness and high wear resistance are the main characteristics of carbide products. Then the hardness test for each batch of products becomes an essential part to ensure the hardness of the products.
Each batch of our company’s products will be tested by testing sample strips to see if the Rockwell hardness is up to standard. In order to ensure the accuracy of the measurement, the surface of the alloy is ground off at least 0.2 mm before the measurement, and the surface roughness Ra is less than or equal to 0.2 micron. Due to the high hardness of the carbide, the diamond indenter is easily damaged, so the diamond indenter is also tested before the test to ensure the accuracy of the measurement.
The hardness test can reflect the mechanical properties and differences of carbide materials under different chemical composition, working environment. Qualified products can be applied to various harsh working environment and play its higher performance.
Ltd. firmly establishes the consciousness of “quality first, customer first”, treats the product quality never satisfied and strives for perfection. We are determined to create the best quality tungsten carbide products.
