Can you carburize stainless steel? 5 Key Insights

Yes, stainless steel can be carburized.

This process involves a high-temperature treatment that allows for the carburization of various stainless steels, including austenitic stainless steels which were previously difficult to carburize.

The treatment is particularly effective for the 13Cr series stainless steel, enhancing its wear resistance.

The results from current tests indicate that the hardness can reach above Hv800, and the carburizing depth can extend to 2~3 mm.

This treatment makes stainless steel with a high carbon surface a viable substitute for materials like SUS-44OC.

Can you carburize stainless steel? 5 Key Insights

1. Types of Stainless Steel Suitable for Carburizing

The process is effective on various stainless steels, but notably, it has been shown to be highly beneficial for the 13Cr series, which requires enhanced wear resistance.

This series is known for its corrosion resistance but often lacks sufficient hardness and wear resistance for certain applications.

Carburizing addresses this by increasing the surface hardness and wear resistance without compromising the core material's properties.

2. Techniques and Equipment Used

The RVN vacuum carburizing furnace, produced by SIMUWU, is highlighted as a high-quality option for this process.

This furnace ensures precise temperature control and uniformity, which are crucial for effective carburization.

The vacuum environment allows for better control over the diffusion of carbon into the steel, leading to a more predictable and uniform carburized layer.

3. Benefits of Carburizing Stainless Steel

Carburizing not only improves surface hardness but also enhances wear resistance and fatigue strength.

This treatment is particularly advantageous for low-carbon steels but can be extended to stainless steels to achieve similar benefits.

The process allows for a flexible core material with a hardened exterior, which is ideal for applications requiring both strength and durability.

4. Depth and Hardness Achieved

Traditional carburizing methods could achieve a depth of about 3.5 mm, but with vacuum carburizing, depths of up to 7 mm are possible.

This deeper carburizing is achieved by maintaining a high surface carbon potential during the process, which accelerates the diffusion of carbon into the core of the material.

The hardness achieved can exceed Hv800, making the material suitable for demanding applications.

5. Recarburization of Decarburized Materials

Another application of this technology is the recarburization of materials that have undergone decarburization in previous processes.

This is particularly useful for materials like die steel and high-speed steel, where a decarburized layer can be detrimental to performance.

By controlling the surface carbon potential, these materials can be effectively recarburized, restoring their mechanical properties.

In summary, carburizing stainless steel is a viable and effective method to enhance the mechanical properties of stainless steels, particularly those that require increased wear resistance and hardness.

The use of advanced vacuum carburizing furnaces allows for deeper and more controlled carburization, making it a valuable process for a range of industrial applications.
