DETAILS
Products in this category are iron-based with a large amount of chromium carbides in a hard matrix. These alloys are designed for severe sliding abrasion accompanied bylow or moderate impact.
Feature.Products.PDP.DetailsMain.Features
- Designed to resist severe abrasion
- It exhibits higher alloy and higher abrasion resistance than Wearshield® ABR, Wearshield® 44 or Wearshield® ME
- Can be used on carbon, low alloy, stainless, and manganese steels
- Deposits consist of primary carbides in a matrix of austenite-carbide eutectic

NOTES
Note |
---|
⁽¹⁾ Preferred polarity is listed first. |
NOTE: The deposit is not machinable or forgeable. Cooling rate does not significantly influence abrasion resistance. Deposit will usually cross check. |
If more than two-layer build-up is required, use Wearshield® 15CrMn (preferred), Wearshield® BU or Wearshield® BU30 for the preliminary layer or layers under Wearshield® 60. |
On manganese steel, use Wearshield® Mangjet® or Wearshield® 15CrMn as build-up. |
Preheat is not generally necessary except to be sure that work is in room temperature range 25° - 45°C (75° - 100°F). |
However, preheat of 120° - 200°C (250° - 400°F) may be necessary to prevent heat affected zone cracking on high carbon steel or low alloy steel base metals. |
If more than two layers must be used, or if cross checks must be eliminated, preheat to 650°C (1200°F). |
Prolonged or repeated heating of manganese steel base metal over 260°C (500°F) can cause embrittlement and spalling. |
Avoid base metal embrittlement by: • Limiting the temperature 260°C (500°F) at distances of 13 mm (1/2 in) away from the weld. • Minimizing the time at elevated temperatures. |
The correct welding technique is a vertical electrode with a 3.2 - 4.8 mm (1/8 - 3/16 in) arc length. The large ball on the end of the electrode should never touch the puddle. This technique will give a smooth transfer, low spatter and smooth bead. |
