Can a Cermet Saw Blade be used for cutting stainless steel?

Cermet saw blades are a popular choice in the metal - cutting industry due to their unique properties. As a cermet saw blade supplier, I often receive inquiries about whether these blades can be used for cutting stainless steel. In this blog, I will delve into the science behind cermet saw blades and their suitability for cutting stainless steel.

Understanding Cermet Saw Blades

Cermet is a composite material composed of ceramic and metal. The ceramic component provides high hardness, wear resistance, and heat resistance, while the metal component contributes to toughness and shock resistance. This combination gives cermet saw blades several advantages over traditional high - speed steel (HSS) or carbide saw blades.

Cermet saw blades are known for their ability to maintain a sharp cutting edge for an extended period. They can operate at higher cutting speeds, which increases productivity. Additionally, they generate less heat during the cutting process, reducing the risk of workpiece deformation and improving the quality of the cut surface.

Properties of Stainless Steel

Stainless steel is an alloy that contains at least 10.5% chromium, which gives it excellent corrosion resistance. There are various grades of stainless steel, each with different compositions and properties. For example, austenitic stainless steels, such as 304 and 316, are non - magnetic and have good formability and weldability. Ferritic stainless steels, on the other hand, are magnetic and have lower ductility but higher resistance to stress corrosion cracking.

One of the challenges of cutting stainless steel is its work - hardening tendency. When stainless steel is subjected to mechanical stress during cutting, its surface hardness can increase rapidly, making it more difficult to cut. Moreover, stainless steel has relatively low thermal conductivity, which means that heat generated during cutting tends to accumulate at the cutting edge, leading to premature tool wear.

Can Cermet Saw Blades Cut Stainless Steel?

The answer is yes, cermet saw blades can be used for cutting stainless steel, but with certain considerations.

Advantages of Using Cermet Saw Blades for Stainless Steel

• High - speed cutting: Cermet saw blades can cut stainless steel at higher speeds compared to HSS saw blades. This not only reduces the cutting time but also minimizes the work - hardening effect because the blade passes through the material quickly before significant hardening occurs.
• Wear resistance: The ceramic component in cermet provides excellent wear resistance. When cutting stainless steel, which is a relatively hard and abrasive material, cermet saw blades can maintain their cutting edge for a longer time, reducing the frequency of blade replacement.
• Surface finish: Cermet saw blades can produce a smooth and clean cut surface on stainless steel. This is important in applications where a high - quality finish is required, such as in the manufacturing of precision parts or architectural components.

Limitations and Considerations

• Grade of stainless steel: Different grades of stainless steel have different hardness and machinability. For example, some high - alloy stainless steels with high levels of nickel, molybdenum, or other elements can be extremely difficult to cut. In such cases, the cutting parameters may need to be carefully adjusted, and in some instances, a different type of blade may be more suitable.
• Cutting parameters: Proper selection of cutting parameters is crucial when using cermet saw blades to cut stainless steel. The cutting speed, feed rate, and depth of cut need to be optimized to ensure efficient cutting and prevent blade damage. Generally, a lower feed rate and a moderate cutting speed are recommended to avoid excessive heat generation and blade chipping.
• Coolant: Although cermet saw blades generate less heat than some other types of blades, using a coolant can still be beneficial when cutting stainless steel. A coolant helps to dissipate heat, reduce friction, and flush away chips, which can improve the cutting performance and extend the blade life.

Applications of Cermet Saw Blades in Stainless Steel Cutting

Cermet saw blades are widely used in various industries for cutting stainless steel.

• Automotive industry: In the automotive manufacturing process, cermet saw blades are used to cut stainless steel tubes and bars for exhaust systems, fuel lines, and structural components. The high - speed cutting and good surface finish provided by cermet saw blades contribute to the efficiency and quality of the production process.
• Construction industry: For architectural applications, such as handrails, facades, and structural frames made of stainless steel, cermet saw blades can produce precise and clean cuts. This is essential for ensuring the proper fit and aesthetic appearance of the final products.
• Manufacturing of precision parts: In the production of precision parts, such as valves, pumps, and fittings, cermet saw blades are used to cut stainless steel with high accuracy. The ability to maintain a sharp cutting edge and produce a smooth surface finish is crucial for meeting the strict quality requirements of these parts.
