WT-25 Weartech Cobalt Base Alloys Hardfacing Welding Electrode (same as alloy L605).

WT-25 Coated Welding Electrode is a low carbon, tungsten strengthened, cobalt chromium alloy.
Description/Applications:
This tungsten strengthened cobalt-chromium alloy is the cast version of the wrought alloy L605.
WT-25 Coated Welding Electrode has been found to have exceptional thermal fatigue resistance and is useful for tools to work hot steel.
The alloy also resists hot metal on metal wear.
The deposited weld metal with WT-25 Coated Welding Electrode has an excellent strength, good oxidation resistance up to 980°C, very good sulfidation resistance, and relatively good resistance to wear and galling.

Typical Chemical Analysis %:
C 0.1, Cr 20, Co bal, W 15, Ni 10, Fe <3, Si 1, Mo <0.5, Mn <1.5.

Typical Mechanical Properties:
Typical Hardness: 16, 24 Rockwell C

Note: The typical hardness values listed above are for multilayer welds. Hardness values for single deposits will be lower because of dilution from the base metal.

Available diameter: 2.4 - 3.2 - 4.0 mm, other diam. on request.
