High Chromium Cast Steel Ball
High Chromium Cast Steel Ball is made by introducing a fluid melt into a mold that is allowed to cool in the shape of a sphere. Four main elements are required in the casting process: the pattern, the mold, the core, and the partial pattern, from which the original template is prepared, created in the corresponding cavity of the casting material. The core is used to make the pipe or hole in the final die, and this part is the final output of the process. Casting can be used to form hot, liquid metals. The abrasive medium is heat treated to achieve the required combination of hardness, toughness and microstructure to ensure an excellent combination of wear resistance and toughness.
Shandong jinchi heavy industry co., ltd. is a contemporary manufacturing corporation integrating r & d, production and sales! The main products of the company are wear-resistant steel balls, wear-resistant steel rods, wear-resistant steel forgings, mill lining plates, steel structures, and mine accessories. Excellent creates brand and fine creates blessings; superior control standards, sophisticated system gadget, and tremendous personnel have applied the right excellent enchantment in each hyperlink of the production procedure, and found out the comprehensive upgrading of product nice.

High Chromium Cast Steel Ball quality index
High Chromium Cast Steel Ball quality indicators:
Chromium content ≥10.0%, carbon content between 1.80%-3.20% are called high chromium ball, the national standard requirements of high chromium ball hardness (HRC) must be more than 58, impact value AK ≥3.0J/ 2, if the hardness of high chromium ball must use high temperature quenching + tempering treatment (at present domestic high chromium ball quenching oil quenching and wind quenching two quenching methods), If the test hardness (HRC) is below 54, the High chromium cast steel ball has not been quenched.
