Anucha Metals stands out as a reliable manufacturer and supplier of High Speed Steel M35 Bars right in the heart of Bangkok, Thailand. They offer top-notch tool steels that are renowned for their exceptional performance in high-temperature and high-stress situations. These bars are a go-to choice for cutting tools, drills, and milling operations, thanks to their remarkable wear resistance, hardness, and red-hardness features. With a focus on precise composition and controlled manufacturing processes, Anucha Metals guarantees an excellent surface finish, precise dimensions, and consistent mechanical strength in every single product.
The High Speed Steel M35 Bars are made up of a blend of carbon, tungsten, molybdenum, vanadium, cobalt, and chromium, all of which work together to boost hardness, edge retention, and heat resistance. The inclusion of cobalt (around 5%) enhances the alloy’s hot hardness and tempering stability, enabling tools crafted from M35 to keep their cutting edge even at high temperatures. These bars are known for their high tensile strength, impressive toughness, and superior grindability.
