PHILHARD 350R
DIN AWS SPECIFICATIONS: NONE
JIS SPECIFICATION: DF2A-350-R
OTHER SPECIFICATION:DIN 8555:El-350
I. APPLICATIONS:
For hardfacing, rebuilding or buffering with PHILHARD 350R, 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
II. DESCRIPTION:
PHILHARD 350R 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 PHILHARD 350R 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
