PHILHARD SKD 61
I. APPLICATIONS:
Hardfacing of piercing form, dies, forging molds, die casting molds, etc.
II. DESCRIPTION:
PHILHARD SKD 61 is a lime titania type electrode depositing air-hardenable weld metal whose composition is similar to alloy steel SKD-61 or AISI H 13 steel. Its weld metal has excellent toughness and crack resistibility . As its weld metal is excellent heat resistance and impact resistance, it is suitable for hard surfacing of metal dies which require the durability. But machining is impossible for its higher hardness as welded condition.
III. NOTES ON USAGE:
-
Preheat at 150ºC and over in general.
-
In the case of multi-layer build-up welding or hardenable steel welding, underlay with low hydrogen type electrode (PA-52 or PA-8016).
-
Dry the electrodes at 300~350ºC for 30~60 minutes before use.
