HORDA 420

HORDA 420
: EN ISO 14343 G 13
: AWS A 5.9 ER 420
: ГОСТ 10543 30X13

Solid wire with a high content of carbon and 13% Cr, which can be used for repair and hardening wear-resistant surfacing.

The corrosion-resistant build-up layer has a martensite structure with chromium carbides.

HORDA 420 is recommended for products operating under abrasive wear. When surfacing, preheating and a concomitant temperature of at least 200° C are required, followed by a slow cooling down.
