DUROLOY Co

Produktinformation

DUROLOY CO can be applied by shielded arc welding, resulting in a heat and wear resistant hard facing. This deposit is resistant to oxidation, reduction and other corrosive media.
When first applied to hot forging dies, the overlay is very cohesive. Exposed to impact and pressure load and even at elevated temperature, the resulting hard facing deposit increases
in hardness up to 400 HB without deforming. For thick layers of DUROLOY CO, a buffer layer based on the alloys 1.4337 or 1.4370 should be applied. Depending on the base metal,
the area to be hard faced should be preheated to 300 °C – 400 °C. Application: For hardfacing on forging dies and other hot working tools.
