17NiCrMo6-4鋼丸棒
17NiCrMo6-4 (UNI EN 10084) IS THE NEW DESIGNATION OF 18NiCrMo5 (UNI 7846). IT IS THE MOST COMMON CASE-HARDENING STEEL AND IN EUROPEAN IT IS USED FOR ITS EXCELLENT CHARACTERISTICS THAT MAKE IT SUITABLE FOR SEVERAL APPLICATIONS. IT HAS A MEDIUM-HIGH HARDENABILITY AND A GOOD MACHINABILITY.AFTER CASE-HARDENING AND HARDENING TREATMENTS, THE SURFACE REACHES AN ELEVATED HARDNESS.17NiCrMo6-4 IS USED FOR THE PRODUCTION OF MECHANICAL PARTS, WHICH ARE SUBMITTED TO WEAR (GEARS, CAMSHAFTS, BUSHINGS, PINIONS).IS USED FOR THE PRODUCTION OF MECHANICAL PARTS, WHICH ARE SUBMITTED TO WEAR (GEARS, CAMSHAFTS, BUSHINGS, PINIONS).
