2 HIGH-CHROME ALLOYED IRONS FOR CAST GRINDING BALLS REMARKS: * O ur brands are according to the requirements of the international standard EN ISO 12513; ** The Carbon and other alloying elements (excepting Cr) contents are established depending the destination of the product, the width of the cast part, the hardness and the heat treatment type; *** We can produce any other brands of high alloyed wear resistant irons, according to the international standards or to the material specification of the customer. BRAND *%Cr HARDNESS HRC DESTINATION XCr dry/wet grinding, cement / coal mills XCr dry/wet grinding, cement / coal mills XCr dry/wet grinding, cement / ore mills

5 Microstructure of ball Ø 60mm diameter Material: XCr 14 - cast Iron high alloyed with Chrome Stage: after heat treatment HARDNESS & MICROSTRUCTURES High and constant hardness of the cast grinding media is the determining parameter for a low and uniform wear rate. High and constant hardness of the cast grinding media is the determining parameter for a low and uniform wear rate. Heat treatment applied is managed in direction of the whole-section hardening, avoiding brittle metallic base, viewing the best performances in exploitation: high productivity, low consumption, low const. Heat treatment applied is managed in direction of the whole-section hardening, avoiding brittle metallic base, viewing the best performances in exploitation: high productivity, low consumption, low const. Center of ball, size 200:1; 57HRC At 1/2 radius, size 200:1; 59HRC Exterior of ball, size 200:1; 60HRC
