Our hardfacing welding wires are meticulously designed to enhance the efficiency and lifespan of various components such as screw conveyors, augers, rendering screws, and similar parts. Get in touch with us today to discuss your needs!


Using hardfacing welding wire for surface hardening metal parts is cost-effective


Industrial equipment is designed to last for many years. Therefore, many companies need several years to replace their worn metal products. Hardfacing welding wire can be used to rebuild old machinery or applied to new equipment for hard surfacing to make it more wear-resistant. Hardened surface parts that have been in use for many years mean that 25-75% of replacement part costs can be saved.


Surface hardening with hardfacing welding wire on the latest equipment can help extend the lifespan of parts by 300%. Common applications include:


Excavator plowshares

Just like any other construction equipment, excavator plowshares undergo continuous wear due to daily outdoor heavy loads, resulting in significant reduction in dimensions and strength of parts.

By hardfacing these parts, the overall lifespan of the machinery can be extended many times over while significantly reducing investment.


Sugarcane crusher rollers

Sugarcane crusher rollers constantly apply pressure to crush sugarcane for processing sugar. Sugarcane is a powerful plant that can test these metal parts.

Hardfacing is a common procedure to extend the lifespan of these parts, reduce production costs, and downtime.


Mining crusher rollers

The mining industry is closely related to hardfacing. Materials obtained from mines need to be crushed for processing.

Even though these crushing rollers are made of hard materials, they can wear out quickly because they deal with strong minerals all day. Therefore, hardfacing is necessary for mining crushing rollers.

So why wait? Try our hardfacing wire today and experience the benefits of superior performance and durability. Contact us now to learn more about our products and services.


What is Hardfacing Welding?


Hardfacing welding is the process of applying a tougher material onto a base metal to make it more durable or extend its lifespan. Also known as hard surfacing, surface welding, or cladding, hardfacing involves welding a harder material onto the base metal using specialized welding rods, filler rods, or hardfacing welding wire. Our company not only provides hardfacing welding wire but also offers hardfacing wear plates and hardfacing welding machines!


Hardfacing technology aims to form a highly dense and thick layer (1 to 10 millimeters) of wear-resistant material over the base metal with high bonding strength. Hardfacing can increase the ductility, hardness, corrosion resistance, and erosion resistance of the original parts, thereby extending their lifespan and reducing replacement costs.


Why Might You Need Hardfacing Welding Wire?


All metal components, even when used under normal conditions, undergo wear over time. This can lead to their functional failure, necessitating the replacement of worn-out parts.Questions? Need Help?


In certain industrial applications such as mining or agriculture, this situation may occur more frequently. For any metal parts prone to wear during use, using hardfacing welding wire to harden their surfaces is an ideal choice. In essence, surface hardening with hardfacing welding wire can help:


Reduce downtime for replacing worn or damaged parts

Decrease inventory of spare parts since they are not needed

Extend the lifespan of equipment


Which Metal Parts Can Use Hardfacing Welding Wire?


Low-carbon steel and low-alloy steel with carbon content below 1% can undergo surface hardening with hardfacing welding wire. Medium-carbon steel and low-alloy steel are very common as they have higher strength and better wear resistance than low-carbon steel. High-carbon alloys may require special buffering layers.


The following metals can undergo surface hardening with hardfacing welding wire:


Stainless steel

Manganese steel

Carbon steel and alloy steel

Cast iron

Nickel-based alloys

Copper-based alloys


Low-carbon steel and low-alloy steel are magnetically attracted and can be easily distinguished from non-magnetic austenitic manganese steel. Many low-alloy and high-carbon steels are used in manufacturing equipment and components, especially those requiring high strength and wear resistance. They are not easily distinguishable but should be identified to determine the appropriate preheating and post-heating temperatures. As the alloy content increases, the requirements for preheating and post-heating become more critical.


For example, steel made from 4130 typically requires preheating at 400°F (200°C). Steel used for railroad tracks typically has higher carbon content and requires preheating of at least 600°F to 700°F (315°C to 370°C). Manganese steel does not require preheating. In fact, measures should be taken to keep the base metal temperature below 500°F (260°C).
