Does anyone have experience in flame hardening localised areas of coreboxes made of grey iron,used in the making of shell cores to extend the wear life? I am looking at alternative methods of extending our tool life.
I am looking for alternative materials to use for patterns in our high pressure sand moulding foundry. We are currently using P20 Tool Steel, sometimes nitrided. With certain pattern geometries, the patterns will wear beyond the accepted dimensional tolerance before expected. What materials do...
