Hey there! As a supplier of saws blade steel strip, I've been getting a lot of questions lately about how to increase the heat resistance of these strips. Well, you've come to the right place! In this blog post, I'm going to share some tips and tricks that I've learned over the years in the industry.
Understanding the Basics of Heat Resistance
First things first, let's talk about why heat resistance is so important for saws blade steel strips. When a saw blade is in use, it generates a significant amount of heat due to the friction between the blade and the material being cut. If the steel strip doesn't have good heat resistance, it can lead to a whole bunch of problems. The blade can lose its hardness, which means it won't cut as effectively. It can also warp or even break, which is not only dangerous but also costly to replace.
So, what makes a steel strip heat-resistant? It all comes down to the composition of the steel. Different alloys and elements can be added to the steel to improve its heat resistance. For example, chromium is a common element that is added to steel to increase its resistance to oxidation and heat. Nickel is another element that can enhance the toughness and heat resistance of the steel.
Choosing the Right Steel Alloy
One of the most important steps in increasing the heat resistance of saws blade steel strip is choosing the right steel alloy. There are several types of steel alloys that are commonly used in saw blade manufacturing, each with its own unique properties.
Gang Saw Blades Steel
Gang saw blades steel is a popular choice for many saw blade applications. This type of steel is known for its high strength and good heat resistance. It can withstand the high temperatures generated during cutting without losing its hardness or shape. You can learn more about Gang Saw Blades Steel on our website.
D6A High Carbon Steel Strip
D6A high carbon steel strip is another excellent option for saw blades. This steel alloy has a high carbon content, which gives it excellent hardness and wear resistance. It also has good heat resistance, making it suitable for high-speed cutting applications. Check out our D6A High Carbon Steel Strip for more details.
Bimetal Steel Strip
Bimetal steel strip is a combination of two different types of steel, typically high-speed steel and carbon steel. This combination allows the saw blade to have the best of both worlds - the high cutting performance of high-speed steel and the toughness and heat resistance of carbon steel.

Heat Treatment Processes
In addition to choosing the right steel alloy, heat treatment processes can also play a crucial role in increasing the heat resistance of saws blade steel strip. Heat treatment involves heating the steel to a specific temperature and then cooling it at a controlled rate to achieve the desired properties.
Quenching
Quenching is a heat treatment process where the steel is heated to a high temperature and then rapidly cooled by immersing it in a quenching medium, such as oil or water. This process helps to increase the hardness of the steel by forming a martensitic structure. However, quenching can also make the steel brittle, so it is often followed by a tempering process.
Tempering
Tempering is a process where the quenched steel is heated to a lower temperature and then cooled slowly. This process helps to relieve the internal stresses in the steel and reduce its brittleness. It also improves the toughness and heat resistance of the steel.
Normalizing
Normalizing is another heat treatment process where the steel is heated to a high temperature and then cooled in air. This process helps to refine the grain structure of the steel, which can improve its strength and toughness. It also helps to reduce the internal stresses in the steel.
Surface Coating
Another way to increase the heat resistance of saws blade steel strip is by applying a surface coating. Surface coatings can provide a protective layer on the surface of the steel, which can help to reduce friction and heat generation during cutting.
Titanium Nitride (TiN) Coating
Titanium nitride (TiN) is a common surface coating that is used on saw blades. This coating has a high hardness and wear resistance, which can help to extend the life of the saw blade. It also has good heat resistance, which can help to reduce the temperature of the blade during cutting.
Aluminum Titanium Nitride (AlTiN) Coating
Aluminum titanium nitride (AlTiN) is another advanced surface coating that is used on saw blades. This coating has even better heat resistance and wear resistance than TiN coating. It can withstand higher temperatures and provide better performance in high-speed cutting applications.
Proper Maintenance and Usage
Finally, proper maintenance and usage of the saw blades are also important for increasing their heat resistance. Here are some tips to keep in mind:
- Keep the saw blades clean: Make sure to clean the saw blades regularly to remove any debris or chips that may accumulate on the surface. This can help to reduce friction and heat generation during cutting.
- Use the right cutting speed and feed rate: Using the right cutting speed and feed rate can help to prevent the saw blades from overheating. Make sure to follow the manufacturer's recommendations for the cutting speed and feed rate.
- Lubricate the saw blades: Lubricating the saw blades can help to reduce friction and heat generation during cutting. Use a suitable lubricant that is recommended for the type of material being cut.
Conclusion
Increasing the heat resistance of saws blade steel strip is a complex process that involves choosing the right steel alloy, applying the appropriate heat treatment processes, using surface coatings, and proper maintenance and usage. By following these tips and tricks, you can improve the performance and lifespan of your saw blades.
