POSTALLOY® 2892-SPL
Medium hardness build-up wire with excellent compressive strength.
Recommended for applications where weld deposits must provide good metal-to-metal wear resistance, but still be machinable "as welded".
Use on carbon and low alloy steels.
Specifications:
|
Wire Type: |
Metal-cored, Gas-shielded.
Deposits are slag-free. |
Weld Deposit Properties:
- Hardness: 33 - 38 Rc
- Maximum Deposit Thickness: Unlimited.
- Deposits can be flame cut.
- Machinable with carbide tools.
Applications:
Because of its hardness and wear resistance, this wire is primarily intended as a buildup or final overlay for:
- Machine components.
- Gear teeth.
- Steel mill parts.
- Keyways.
- Undercarriage.
- Carbon steel railroad track components.
- Parts of earth moving and mining equipment.
Welding Parameters - Use DC Reverse Polarity
