1018 low-carbon steel (mild steel) - Co., Ltd.1018 hot rolled steel is a general purpose low carbon steel with good case hardening qualities. It has higher manganese content than other low carbon grades, such as 1020. Due to the higher manganese content, 1018 is best used for carburized parts because it produces a harder and more uniform case.
A rolling roller is made up of sheath layer made of high-speed steel and core made of spheroidal graphite cast iron alloy through centrifugal casting. Rare-earth elements (0.03-0.5%) is added to molten steel for sheath before pouring for modifying treatment and protecting agent (3-5 kg/sq.m) is added after pouring for preventing oxidation of internal surface of sheath.
