Hard-Revishield®60-СG - is a self shielded, open arc, flux cored tubular electrode that produces a primary carbide weld deposit. Although, Hard-Revishield®60-СG designed primarily for the open arc process it can be used with a neutral flux to improve the weld shape, minimise fume and remove arc glare.
Hard-Revishield®60-СG produces an primary carbide weld deposit with a hardness range of 55-60HRc. The primary carbide microstructure makes Hard-Revishield®60-СG ideally suitable for applications of severe abrasion.

When welding with Hard-Revishield®60-СG stringer beads should be employed. Weaving is not advised since wide weaves generally increase the check crack spacing which can result in deposit spalling. Preheat is not necessary when surfacing austenitic substrates such as stainless steels and manganese steels, although the interpass temperature should be limited to about 260°C for manganese steels.
For low alloy and high carbon steels a preheat of 200°C is necessary to prevent heat affected zone.
The weld metal is not machinable or forgeable and it readily check cracks.
The deposit thickness is usually limited to 2 layers, as excessive build-up will result in chipping and fragmentation.
For applications requiring build-ups in excess of 2 layers, buttering layers of Elerep®307, Elehard®350-GP or Hard-Revishield®350-GPS.
Alternatively, a preheat of 650°C can be used to eliminate the formation of check cracks.
