CO-DI-TRA - Hammers for Shredders

CO.DI.TRA produces hardened alloy hammers. The conventional hammers produced using Manganese steel have good ductility, but these cannot develop higher hardness under normal working conditions. The result is a faster wear. We have studied different type of alloy steels according to the exigencies. Using proprietary heat treatments process we can obtain hammers with whole core hardness or softer hardness near the bore and harder impact working part. The best compromise  is achieved by suitable heat treatment of hammers in order to ensure adequate ductility.
