Applications / Features

High-performance electrode for wear-resistant

Hardfacing welds on unalloyed and low-alloy and

high-alloy, heat-, corrosion- and acid-resistant

steels and steel castings.

Distinguished by a particularly favourable

coefficient of friction under wear conditions "metal against

metal".

temperature resistance up to 800°C;

up to 1100 °C for short periods.

Machining by chip removal is possible to a limited extent.

Applications

High-temperature special alloy for

Hardfacing welds that are subjected to temperature cycling

are subjected to.

Particularly for impact- and shock-resistant hard surfacing

of hot-work tools such as:

forging dies,

hot piercing punches,

Hot trimming tools.
