NIDURIT 61
AWS Specification: EFeCr-Al
JIS Specification:

RUTILE/BASIC TYPE

Other Specification:

DIN E10-UM-60-GRZ

I. APPLICATIONS:

NIDURIT 61 is suited for highly wear resistant claddings on parts subjected to strong grinding abrasion combined with medium impact, such as conveyor screws, scraper blades, mixer wings, sand pumps and sugar cane cutter knives. Also as final layer on crusher jaws.

II. DESCRIPTION:

NIDURIT 61 has excellent welding characteristics and a very easy slag removal. The homogeneous and finely rippled seam surface does, for most applications, not require any finishing by grinding.

Approx. Recovery:  160%

III. NOTES ON USAGE:

Hold electrode as vertically as possible, keep a short arc. Preheating is in general not necessary. For multipass-applications a cushion layer with NSS-307 or NHF-Cromang is recommended in order to prevent hardening cracks in the weld deposit. Re-dry electrodes that have got damp for 2h/300ºC
