              \ud83d\udd25 Heat Treatment Applications: Surface Hardness up to 65 HRC<\/h3>\n

              Dogamakina, in order to increase the strength of construction machinery parts Heat treatment solutions up to 65 HRC<\/strong> offers. Particularly high wear resistance is required such as pins, bushings and gears<\/strong> The heat treatment process plays a critical role in the performance of parts.<\/p>\n

              Applied Heat Treatment Types:<\/h4>\n
                \n
              • \n

                Induction Hardening<\/strong>
                \u2192 With localised hardening, only the contact surface of the part is hardened.
                \u2192 Application: bucket pin, pivot pin, shaft<\/p>\n<\/li>\n

              • \n

                Carburising (Carburizing)<\/strong>
                \u2192 By impregnating the steel surface with carbon, high hardness is obtained on the surface and toughness is obtained inside.
                \u2192 Application: flange adapters, gear shafts<\/p>\n<\/li>\n

              • \n

                Nitration (Nitriding)<\/strong>
                \u2192 Wear and corrosion resistance of the surface is increased.
