Description
Lincoln Lincore® 55 Flux-Cored MIG Welding Wire - 10lb Spool (ED037254)
Ideal for building up on carbon and low alloy steels. Use as an underbase for carbon steel parts prior to hardfacing. Great compressive strength under heavy loading. Deposits are generally crack free, machinable and can be flame cut. Deposit thickness is unlimited. Used in Metal-to-Metal wear applications, works best in non-lubricated rolling or sliding.
Features
- To be used on carbon steel, low alloy steel and manganese steel
- Deposit is unlimited layers
- Delivers a deposit which resists metal-to-metal rolling or sliding wear as well as mild abrasion
| Note |
|---|
| Cold parts should be warmed to at least 25°C (75°F). Higher preheat of 150 - 260°C (300 - 500°F) may be necessary on thick parts or heavy sections. |
| Interpass temperatures between 150°C (300°F) and 200°C (400°F) do not affect the hardness of Lincore® 55 significantly. |
