Granulating Blades: Metal is a broad concept. Of the 90 stable elements, 65 are categorized as “metals”. Many of these elements do not exist in pure form and cannot be used for metalworking. However, there is also a large group of metals that is indeed used. These include: Titanium, Vanadium, Chromium, Manganese, Iron, Nickel, Copper, Zinc, Zirconium, Niobium, Molybdenum, Tungsten, Aluminum, Silver, Gold and Platinum.
Tool Steel is usually associated with tool and mold making. However, it also has applications in many other areas where properties such as hardness, wear resistance, tensile strength and toughness required. One can distinguish two main groups, low-alloy and high-alloy containing three subgroups depending on the scope, GS for cold work, hot work, and plastic injection.
The compound of carbon and Fe with elements such as Si, Mn, Cr, Ni, and others are the basis of tool steels and give it the required properties. The properties of tool steel for Granulating Shear Blades are determined by a heat treatment.
Steel is a widely used construction material and consists predominantly of carbon and iron. There are three types of steel can be distinguished: structural steel, tool steel and machinery steel.
Structural steel has (roughly) the following characteristics:
- Low carbon content
- Relatively soft material
- Good hot and cold forming
- Good weldability (without hard / too brittle)
Tool steel has carbon content between 0.6% and 1.5%. It is a high alloy steel containing more than 5% of alloying elements. Tool steel is also called high speed steel (HSS) called. The material retains its hardness at higher temperatures and is therefore very suitable for tools, such as metal and concrete drills, hammers, cutting tools, measuring tools and gauges hot. The strength and hardness will be partly determined by the chemical composition of the material and heating processes.
- Strong and hard
- Resistant to shocks
- Easy to change
- High alloyed
Alloy metal is almost never used in the industry in pure form. An alloy is a mixture of different metals. The most famous is steel, a mixture of iron, carbon and other metallic elements. Metals are available in different properties as stainless steel, in which a high content of Chromium (min 11% to 12%) is added to protect against corrosion. Several alloying elements have an effect on the properties of the metal. By the addition of various alloys, the tensile strength, hardness, corrosion resistance, yield strength and wear resistance can be improved.
