5 Types of Slitting Blade Materials
We use different materials for slitting blades on different types of slitting machines.
It is important to choose the ideal metal slitting blade material for you to ensure you achieve the longest blade life, minimize maintenance-induced downtime, and then achieve the ideal cut. But do you know the slitting blade material? Don‘t worry! This article will tell you about the 5 materials of slitting blades.
Slitter Blades
Slitter Blades
1. Semi-high speed (D2 steel)
D2 steel is the most commonly used material for top and bottom blades. It offers a good combination of cost and associated wear life, and is easy to sharpen. It is also a versatile material for shear slitting applications involving plastics and paper. It is often the most cost-effective choice for wear and low budget applications.
2. High Speed Steel (M2 STEEL)
2. High Speed Steel (M2 STEEL)
This steel is also used for top and bottom blades and offers longer wear life because it is harder and tougher than D2 steel. M2 is generally recommended for shear slitting applications involving nonwoven materials and paper because each material is highly abrasive, resulting in shear slitters using 52100 steel blades that must be maintained frequently to replace dull blades. Switching from D2 to M2 allows the operator to increase the run time between blade changes, thereby reducing maintenance-induced downtime.
3. Carbon Steel
3. Carbon Steel
Carbon steel is a steel whose primary gap-filling alloy composition is between 0.12 and 2.0% carbon. As the percentage carbon content increases, the steel has the ability to become harder and stronger through heat treatment. However, it becomes less ductile. Regardless of the heat treatment, higher carbon content reduces weldability. In carbon steels, higher carbon content decreases the melting point.
4. Alloy Steels
4. Alloy Steels
Alloy steels are steels in which a variety of elements between 1.0% and 50% in total are allowed to improve their mechanical properties. Alloy steels are divided into two categories: low-alloyed steels and high-alloyed steels. Each type of steel is a true alloy, but not all steels are called "alloy steels". Even the simplest steel is an alloy of iron (Fe) and carbon (C). However, the term "alloyed steel" is the standard term for steels that contain other alloying elements in addition to carbon.
The following are some of the improved properties of alloyed steel (compared to carbon steel): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and thermal hardness. In order to achieve some of these improved properties, the metal may need to be heat treated.
5. Chromium-Vanadium Steels
The following are some of the improved properties of alloyed steel (compared to carbon steel): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and thermal hardness. In order to achieve some of these improved properties, the metal may need to be heat treated.
5. Chromium-Vanadium Steels
Chromium-vanadium steels (symbol Cr-V or CrV; 6000 series SAE grades) are a group of steels containing carbon (0.50%), manganese (0.70-0.90%), silicon (0.30%), chromium (0.80-1.10%), vanadium (0.18%), and trace amounts of phosphorus and sulfur. Some forms are used as high-speed steels. Both chromium and vanadium make the steel harder enable. Chromium also helps to resist wear, oxidation and corrosion. Both chromium and carbon improve elasticity.
