CATEGORY
TYPE
Iron based SMAW electrode filled with tungsten carbides for extreme wear resistant overlays.
APPLICATIONS
To be aplied on-armour-platings of tools and machine parts in the mining, road construction, well digging, special civil engineering, depression drilling technology, where strongest abrasion by minerals may occur.
PROPERTIES
Dur RU is a steel tube filled with fused tungsten carbides. The weld deposit contains a high amount of tungsten carbides embedded in a steel matrix. The extraordinary hardness of the fused tungsten carbides (WSC) of approx. 2300 HV imply the high build-up wear resistance. It is a dip-coated electrode suitable for electrical welding on AC as well as on DC. The carbon content of the base metal should not exceed 0,45 % in order to avoid lack of fusion.
SUITABLE FOR
Scratchers, mixers, deep drilling, mining, bentonit mixers, cement mixers, stabilisers, impellers, augers etc.
APPROVALS
CE approved
