What are Metal Cutting Blade Material

Selecting the ideal metal cutting blade material for your application ensures that you achieve the maximum blade life, minimize maintenance-induced downtime, and achieve your ideal cuts. Therefore, this article aims to let you know more about metal cutting blade materials.


Semi-High Speed (D2 STEEL)


D2 steel is the most commonly used material for both top and bottom blades. It has a good combination of both cost and associated wear life and is easy to sharpen. It is also a versatile material and can be used in shear slitting applications involving both plastics and paper. It is typically the most cost-effective option for both wear and low budget applications.


High-Speed Steel (M2 STEEL)


This steel is also used for both top and bottom blades and provides increased wear life since it is harder and tougher than D2 steel. M2 is often recommended in shear slitting applications involving nonwoven materials and paper since each is very abrasive and cause Shear slitting machines that employ 52100 steel blades must undergo frequent maintenance to replace dull blades. Switching from D2 to M2 allows operators to increase runtimes between blade changes resulting in less maintenance-induced downtime.


Carbon Steel


Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute (AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60."

As the carbon percentage content rises, 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, the higher carbon content lowers the melting point.


Alloy Steel


Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%. Most commonly, the phrase "alloy steel" refers to low-alloy steels.

Every steel is truly an alloy, but not all steels are called "alloy steels". Even the simplest steels are iron (Fe) (about 99%) alloyed with carbon (C) (about 0.1% to 1%, depending on the type). However, the term "alloy steel" is the standard term referring to steels with other alloying elements in addition to the carbon. Common alloys include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloys include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, and zirconium.

The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. To achieve some of these improved properties the metal may require heat treating.

Some of these find use in exotic and highly-demanding applications, such as in the turbine blades of jet engines, in spacecraft, and in nuclear reactors. Because of the ferromagnetic properties of iron, some steel alloys find important applications where their responses to magnetism are very important, including in electric motors and in transformers.


Chromium Vanadium Steel


Chromium-vanadium steel (symbol Cr-V or CrV; 6000-series SAE steel grades) is a group of steel alloys incorporating carbon (0.50%), manganese (0.70-0.90%), silicon (0.30%), chromium (0.80-1.10%), and vanadium (0.18%) as well as minuscule amounts of phosphorus and sulfur. Some forms can be used as high-speed steel. Chromium and vanadium both make the steel more hardenable. Chromium also helps resist abrasion, oxidation, and corrosion. Chromium and carbon can both improve elasticity.
