Description

4.0MM HARD 600S HARD FACING ELECTRODES – 5KG PACK

Hard Facing 600 is a basic-coated, hydrogen-controlled electrode rod for hard-facing and abrasion-resistance of wearing parts. This electrode is corrosion-resistant, provides extra-hard deposits (54-58 HRC) and can be applied in several layers without cracking. It provides good wetting of the weld metal, very good weld quality, a good-looking weld bead and limited spattering.

Commonly used on rolling mill rollers, tracks, feeders, crushing jaws, ploughshares, excavator shovels, buckets, digger teeth and surfaces exposed to abrasion.

Material to be Welded:

Suitable for ferrous metal surfaces requiring high abrasion resistance, together with impact and heat resistance, and some corrosion resistance. Suitable for use in DC(+), and performs well in all positions.

Basic coated electrode for hardfacing parts on earth and mineral machines, impact drilling and crushing devices, springs, bucket edged and teeth as well as other materials required to have high resistance to wear.

Features and Applications

Applicable in final layer hardfacing of parts of earth and mineral mining machines, impact drilling and crushing devices, guide springs, edges of cutting tools, hard manganese steels, bucket edges and teeth, all of which are made of alloyed or unalloyed steels, as well as in other materials required to have high resistance to wear

Electrode of basic type with thick coating

lnclusion of chromium-silicon alloy, very hard electrode

Weld metal with ductile and cracking resistant behaviours: Crack resistance to impact force due to its high ductility: Machinability of weld metal through grinding only

It is recommended to pre-heat at 200-300°C for welding thick work pieces and materials tending to get hardened: Requirement of 2-3 layers hardfacing to obtain the highest resistance to wear

Suitable for harder and/or higher quality steels to buffer layering with the GeKa electrodes LASER B 50, TEMPO B 63, or, in some cases, with the GeKa electrodes such as ELOX B307, ELOX R 312

Requirement of re-drying for min. 2 hours at temperatures of 300°C
