38 Wear-O-Matic
40 No AWS Classification
DCEP (Electrode Positive)
Open Arc-Hardsurfacing Alloy
Severe Abrasion and Compression
Description: Wear-O-Matic
40 is a hardsurfacing alloy with high chromium and carbon content. It is designed
to provide outstanding
resistance to wear caused by abrasion in combination with compression at temperatures
up to 1000°F
(538°C). Deposits take a high polish and do not gall or seize when subjected
to metal-to-metal wear.
The unique wear-resistant properties
of Wear-O-Matic 40 allow a wide variety of applications:
Crusher parts
Steel mill parts
Hammermill parts
Mill guides Procedure:
The recommended amperage range is 175-300
amperes at 30-35 arc volts. A weaving bead of 1-1/2" (38
mm) in width is recommended. Deposit thickness should be limited to two passes
or 1/4" (6.4 mm). Typical
Mechanical Properties: Wear-O-Matic
40 wire is a high alloy material combining elements to provide extremely high
abrasion resistance
and good compressive strength. The deposit is not heat treatable and cannot be
forged. Weld deposits
cannot be cut with oxy-acetylene torch or by air carbon-arc cutting.
