VHF-300 (low hydro)

AWS Specification: NONE
JIS Specification: DF2A-300B
Other Specification: DIN E1-300

DESCRIPTION

Is a lime type electrode which has stable hardness and toughness.  It is suitable for intermetallic abrasion and medium impact abrasion.  Machining  is  possible in general.  Its hardness increases by quenching after machining.

APPLICATIONS

Hard surfacing of various wheels, cast steel rollers and bulldozer’s parts.

INSTRUCTIONS FOR WELDING

1.)   Preheating is unnecessary in general.  But it is more safe to preheat at 150ºC and over, if large weldments are required to surfacing.

2.)   In the case of high cooling rate, preheat or postheat to avoid difficulty of machining caused by hardening.

3.)   Dry the electrodes at 300~350ºC for 30~60 minutes before use.
