Hard surfacing material

Selection of hardfacing materials
Usually, wear and tear in factories not only involves a single device, but more often involves many different devices working simultaneously. Therefore, when selecting hard-face materials, the form of wear and tear should be taken into account. For example:
1) Main wear mechani**s: This refers to the types of prominent wear on components, such as wear due to abrasion, impact, metal-to-metal contact, or wear caused by overheating or corrosion.
2) Secondary wear mechani**s: Less noticeable wear also affects product quality. For instance, wear patterns that occur due to impact or overheating when processing products at a certain temperature.
3) Requirements: The alloy should possess neutral physical properties and a moderate hardness, capable of resisting impact forces while preventing the occurrence of cracks. Therefore, it is necessary to understand whether your components are machinable or whether it is acceptable to eliminate hardness cracks. Understanding these factors will assist you in selecting a good product.
● Machinability after welding;
● No accumulation of cracks;
● Resistant to wear and impact
These can be achieved through air hardening of alloys.
● Strong wear resistance;
● No cracks;
● Non-processability;
These requirements can be fulfilled using chromium carbide alloys.
● Suitable for 13 manganese steel;
● Impact resistance;
These requirements can be achieved through the use of work-hardening alloys.
Therefore, when selecting hard-face materials, it is important to carefully consider the mechanical properties you require. Corewire's materials are capable of meeting your specific needs.

The question we want to ask you is:
Selecting the appropriate hard-face alloy:
1. What is the base material? There are mainly two types:
Austenitic manganese steel types - These materials are often subjected to significant impact forces. They are tough and exhibit work-hardening properties. Additionally, they are non-magnetic. Low-carbon alloy types - These materials are often subjected to wear or metal-to-metal wear. They are easily su***ced with martensitic or chromium carbide materials through welding.
2. What are the main wear factors?
● Wear and tear;
● Wear between metals;
● Corrosion;
● Popularity;
3. What are the secondary wear factors?
For example, wear caused by impact, such as the teeth of a quarry shovel.
4. What are the process requirements?
● Lathe machining
● Polishing
● Combustion
● Heat treatment
● Cracks can be inspected and accepted
5. Where is it applied?
Our technical staff possesses extensive experience in hard-face applications and can discern which specific components are required for your application.
6. What is the diameter of the welding wire required?
7. How is the welding wire packaged?
The packaging type depends on the type of welding wire, its diameter, and the quantity ordered. Common packaging methods for welding wire include the following:
● 13kg spool
● Coils for 25 and 75 kilograms
● 250 and 300 kilograms, packed in barrels
For weights between 200-300 kilograms, use rolls.
Use appropriate su***cing welding process
When deciding on the appropriate welding process, composition and application are crucial factors. For instance, the base material will determine whether preheating is necessary, and the desired hardness and required thickness must also be taken into account. Our technical team will also provide you with a suitable welding process. If you have doubts about the current process or are considering a new application area, please contact us directly and inform us of your base material and application.
