High-speed steel (HSS) rolls are crucial for metal manufacturing, particularly in rolling mills. The manufacturing process involves multiple stages, including melting, casting, forging, heat treatment, and finishing. Alloying elements like tungsten, molybdenum, and chromium are added to enhance hardness, toughness, and heat resistance. The heat treatment process, which includes austenitizing, quenching, and tempering, is vital for achieving optimal mechanical properties. Precision grinding and quality control ensure that the final product meets strict performance standards. HSS rolls offer exceptional durability and wear resistance, making them ideal for heavy-duty industrial applications.

On Aug 6th, the Korean customer, who has been cooperating with us for a long time, came to the HBW factory. We carried out a magnetic powder inspection on the HSS rings they ordered, and all the HSS rings passed the test. Our customer was satisfied with the test results and discussed the next order

On Nov 13th, our distinguished guest from a subsidiary of the TATA Group in China came to the HBW factory again, checking the first batch of HSS Kocks Rolls and Guide Rollers.HBW always goes through a standardized inspection, including hardness test, UT test, pass test, dimension measurement, etc. T
