JH-143 Flux Cored Hardfacing Welding Wire


● High chromium cast iron is used for surfacing of parts that are subjected to heavy wear and impact. It can withstand high temperatures up to 300 ° C.

● Soluble-coated metals with hard composite carbides in tough substrates perform well in fine and coarse wear.

● Suitable for raw material mill, slag mill, extrusion roll pattern layer surfacing. It is normal to have stress release cracks on the surface after welding.


JH-143 Flux Cored Hardfacing Welding Wire is a metal wire, economical hardfacing alloy designed to resist abrasion. This gas shielded wire can weld misalignment. It is commonly used to cover carbon and low alloy steels, manganese and stainless steels. The welded deposit withstands severe abrasion, moderate impact and metal-to-metal wear. Surface hardening usually does not require any heat treatment. Preheating and postheating are performed if necessary depending on the base material.

In the realm of metal fabrication and repair, hardfacing plays a crucial role in enhancing the durability and longevity of various components. JH-143 Flux-Cored Hardfacing Welding Wire is a remarkable product that offers exceptional performance and reliability in diverse applications.

Flux Cored Hardfacing Welding Wire

Flux-cored hardfacing welding wire is a specialized type of welding consumable designed to deposit a wear-resistant layer on the surface of a metal substrate. It consists of a metal sheath that encloses various alloying elements and a flux compound. The flux compound serves multiple purposes, such as protecting the molten metal from atmospheric contamination, facilitating the transfer of alloying elements, and ensuring proper shielding gas coverage.

Flux Cored Hardfacing Welding Wire - The ultimate solution for all your welding needs.

Our Hardfacing Flux Cored Wire is designed to provide maximum protection against wear and tear, corrosion, and high-temperature environments. With our product, you can ensure that your welding projects are completed with the highest level of strength and durability.

Flux cored wire for overlay welding provides filler metal for creating wear resistant surfaces on metal parts to extend their service life. It is typically used to repair worn parts or to cover new parts. The flux core of the wire helps to deoxidize the workpiece material, stabilize the welding arc, reduce spatter, improve the mechanical properties of the wire alloy and/or protect the molten pool from contamination during the welding process. The wire sits on a coil or spool and is fed through a compatible torch during FCAW (flux cored arc welding) tasks.

JINHUA is an expert in providing flux cored wire for overlay welding, JINHUA will help you choose the right and best flux cored wire for overlay welding, and use JINHUA to develop flux cored wire for manufacturing machine overlay flux cored wire.
