OVERVIEW

Restore and Protect with Lincore® 55

When your heavy equipment is suffering from the grind of metal-on-metal friction, Lincoln Electric's Lincore® 55 is the hardfacing solution you need to get back to work. Designed for the toughest environments in mining, construction, and rail maintenance, this flux-cored wire delivers a durable, wear-resistant surface that stands up to rolling and sliding friction. Whether you are rebuilding crane wheels, repairing mine car rollers, or refurbishing tractor idlers, Lincore 55 provides the toughness required to extend the service life of your critical machinery.

One of the standout features of Lincore 55 is its "unlimited layer" capability. Unlike many hardfacing wires that are restricted to just two or three passes before cracking becomes a risk, Lincore 55 allows you to build up worn parts to their original dimensions using a single wire. This saves you time and money by eliminating the need to buy and switch to a separate "buildup" wire before applying a hard face. Just ensure you follow the recommended preheat and interpass temperature guidelines, and you can weld layer upon layer with confidence.

This wire is self-shielded (FCAW-S), meaning you don't need to drag gas cylinders to the job site. It's perfect for field repairs where wind might blow away shielding gas. The 0.045-inch diameter on a 25 lb spool offers a great balance of deposition rate and control, making it suitable for a wide variety of position work. Invest in Lincore 55 to reduce downtime and keep your heavy fabrication and earth-moving equipment running smoother, longer.

FAQ

No, Lincore® 55 is a self-shielded flux-cored wire (FCAW-S) and does not require external shielding gas. Note: Do not confuse this with Lincore 55-G, which is a gas-shielded variant.

Lincore 55 is designed for unlimited layers, provided that proper preheat and interpass temperatures are maintained to prevent cracking.

The deposit hardness typically ranges from 50 to 59 Rockwell C (RHC), depending on dilution and cooling rates.

This wire is designed to run on DC+ (Direct Current Electrode Positive) polarity.

Cold parts should be warmed to at least 75°F (25°C). For heavy sections, a preheat of 300°F - 500°F (150°C - 260°C) is recommended.

Yes, Lincore 55 is suitable for use on carbon steel, low alloy steel, and manganese steel substrates.

It is specifically designed to resist metal-to-metal rolling or sliding wear, as well as mild abrasion.

This specific product is 0.045 inches (1.1 mm) in diameter.
