JH-242 Flux Cored Hardfacing Welding Wire

JH-242 Hard Surfacing Wire

Can be used for hard surface, low alloy steel and carbon steel applications. Compatible submerged arc fluxes are also available. Options available for applications requiring low temperature toughness and high strength.

Hard surface overlay welding is the process of applying a tougher material to a base metal to make it more durable or extend its service life.

This harder material is welded to the base metal by using special electrodes or filler bars.

They are designed to form a very dense and thick layer (between 1 and 10 mm) on top of a base metal with a wear-resistant material with high bond strength.

The coating material can add ductility, hardness, corrosion and erosion resistance to the original part.

Other names for surfacing are hardfacing, surface welding and cladding.

Some of the base metals that can be hardfaced are

Cast iron

Copper-based alloys

Nickel-based alloys

Stainless steel

Manganese steels

Carbon and alloy steels

Many manufacturing facilities are made from low-alloy and high-carbon steels. Whatever the base material, Hobart's filler metals are a complete solution.

Before starting any overlay process, it is necessary to determine exactly what material it is made of, as this defines the preheat and postheat temperatures that should be applied.

These preheat and postheat settings are even more important because of the higher percentage of alloy in the part content.
