Weighed against other general steel products, the superior characteristics of Steel chemical treatment result from the chemical composition and special treatments for the D2 cold work tool products. Having a carbon content between 0.7% and 1.5%, JIS Channel Bar also contents some rare metals, for instance manganese (Mn), chromium (Cr), molybdenum (Mo), tungsten (W), vanadium (V), cobalt (Co), etc, above which more directly impact the wear resistance. The correct heat treating and quenching operations improve the toughness and strength in the material. Heat treating process utilized to harden steels includes heating them up to a hot temperature (usually at 1204), then quenching to near room temperature, and lastly reheating for some intermediate temperature for tempering (593). Some surface treatments, including coating, etc., are often applied to Boiled Steel Plate.
