Product description

  • Low-alloy flux-cored wire for arc-cladding without gas shielding
  • Rail repair
  • The wire, used in DC+ mode, deposits beads with a good appearance, without spatter, with excellent slag removal and penetration.
  • The deposited metal is bainitic, providing a good combination of wear resistance, mechanical strength and toughness. The microstructure is virtually unaffected by dilution, and remains uniform throughout the thickness of the deposit.

Product application instructions

FCW TLN-O is used to repair pearlitic steels typically containing 0.5% to 0.8% carbon.
Hardness: the hardness of the metal deposited without dilution is between 300 and 400 HV, with an average hardness of less than 350 HV.
The first layer of cladding on a 0.7% carbon pearlitic steel rail has a typical hardness of 350 HV. Heat-affected zone hardness on these steels is less than 350 HV using recommended welding parameters.

Mechanical characteristics

Why choose this cored wire?

FCW TLN-O cored wire is an excellent choice for hardfacing applications where parts are subjected to moderate abrasion, mechanical shock and sometimes even medium temperatures. Here’s why we choose it:

  1. Good compromise between abrasion and impact

FCW TLN-O is formulated to offer good wear resistance while retaining a certain toughness, enabling it to withstand shocks without cracking. This is an asset when working on equipment exposed to mixed stresses (e.g. abrasion + hammering).

  1. Very good for multi-pass reloading

Unlike some very hard wires that become brittle in thick layers, TLN-O allows multiple passes without compromising adhesion or deposit cohesion. Ideal for thicker layers.

  1. Versatile on many parts

This wire is used to recharge components such as :

-worms

-drums, rollers or blades

-wear parts in food processing, sugar mills and quarries

  1. Self-protecting wire

No need for protective gas: easy to use on site, even in less than ideal conditions (outdoors, confined areas, etc.).

In a nutshell

FCW TLN-O is a robust, versatile and practical wire. It is ideal for hardfacing parts subject to moderate to severe wear and mechanical stress. An excellent choice for industrial maintenance and field hardfacing work.
