RUTILE - LOW ALLOY - HIGH EFFICIENCY HARDFACING ELECTRODE WITH EXCELLENT RESISTANCE TO IMPACT LOADING COMBINED WITH MEDIUM ABRASION RESISTANCE
HV-450
CLASSIFICATION
AWS A5.13 EFe2 | DIN 8555 E1-UM-45-GP | JIS Z 3251 DF2A - 450R
PRODUCT DESCRIPTION
The design emphasis of the alloyed weld metal ensures the desired hardness level to the specification is readily achieved as is the deposits maximum resistance to impact loading combined with medium resistance to abrasion. The flux contains the appropriate alloying elements plus iron powder addition and is extruded onto a ferritic wire with a balance of silicates that ensures both coating strength and resistance to moisture absorption.
WELDING FEATURES OF THE ELECTRODE
The electrode is suitable for both AC and DC and is used to best advantage in the flat and HV positions. The arc is smooth and stable weld beads are evenly rippled, of bright appearance and the slag readily detachable. The weld deposit is highly crack resistant under normal circumstances, but on high carbon cast steels or restrained sections of mild steel, a pre-heat of 150°C should be used.
APPLICATIONS AND MATERIALS TO BE WELDED
The tough crack resistant weld deposit may be used as a buffer layer both on mild and high carbon steels prior to depositing harder alloys. Used in its own right, it provides an excellent combination of abrasion and impact resistance making it ideal for hardfacing gear wheels, rails, roller guides, slideways, track wheels, sprockets and similar. Machining is not possible but may be profile ground

OTHER DATA
Electrodes that have become damp should be re-dried at 150ºC for 1 hour.
