DESCRIPTION & APPLICATIONS:
VHF-350B is a general purpose wear-resisting alloy steel electrode. The air- hardening chromium molybdenum (Cr-Mo) alloy steel deposit has high strength and toughness combined with good abrasion resistance. The general characteristics of VHF-350B are:
- The electrode is smooth running and exhibits excellent metal transfer and slag control.
- An electrode suitable for rebuilding of badly worn mild and alloy steel components, and buffer layers prior to deposition of harder deposits.
- Refined and balanced weld metal chemistry giving reliable hardness and crack free deposits
- Deposit hardness: 300 – 350 HV
- A.C./D.C. supply suitable; can be used on low O.C.V. machines (minimum O.C.V. 50)
- Deposit is machinable
For hardfacing, rebuilding or buffering with VHF-350B, the removal of millscale, heavy rust, fatigued or deformed metal, is recommended. Preheat heavy sections or alloy steels in accordance with normal welding practice. This general purpose, metal-enriched coated electrode is suitable for steel companies like:
- Tractor idler wheels, rollers and tracks links
- Surfacing gears, mine rails, shovel pads, pins and clutches
- Rebuilding of shafts, wheel treads and agricultural implements
