Tool steel occupies an important position in the manufacturing industry due to its unique chemical composition and excellent performance. In today’s article, we will delve into tool steel chemical composition and applications.
Tool Steel Chemical Composition and Applications
1. Tool Steel Chemical composition
The chemical composition of tool steel is the basis of its performance, mainly including carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P) and a series of alloying elements such as chromium (Cr), molybdenum ( Mo), vanadium (V), titanium (Ti), etc. The content and proportion of these elements determine the key properties of tool steel such as hardness, strength, toughness, wear resistance, and corrosion resistance.
Carbon is one of the most important elements in tool steel, and its content directly affects the hardness and strength of the steel. An appropriate amount of carbon content can improve the cutting performance and wear resistance of tool steel, but too high a carbon content will lead to increased brittleness and affect the toughness of the steel. Silicon and manganese, as reinforcing elements, can improve the strength and hardness of tool steel, but too high content will also have a negative impact on the plasticity and toughness of the steel.
Sulfur and phosphorus are generally regarded as harmful elements in tool steel. They will reduce the plasticity and toughness of the steel and increase its brittleness. Therefore, during the smelting process of tool steel, the contents of sulfur and phosphorus need to be strictly controlled.
Alloying elements such as chromium, molybdenum, vanadium, titanium, etc. are the key to optimizing the performance of tool steel. Chromium can improve the hardness, wear resistance and corrosion resistance of steel; molybdenum can improve the high-temperature strength and thermal stability of steel; vanadium and titanium can improve the hardness and strength of steel. The addition of these alloying elements enables tool steel to maintain high hardness while also possessing good toughness and wear resistance.
2. Classification of Tool Steel
Based on the chemical composition, tool steels can be divided into two major categories: carbon tool steels and alloy tool steels. Carbon tool steels primarily contain carbon as the main alloying element, with a relatively high carbon content. They are primarily used for the manufacture of cutting tools and molds that do not require high precision. Alloy tool steels, on the other hand, incorporate various alloying elements, resulting in higher hardness, wear resistance, and toughness. These are suitable for the production of precision cutting tools, molds, and measuring instruments that demand high accuracy and durability.
Furthermore, based on their intended applications, tool steels can be categorized into cutting tool steels, mold steels, and measuring tool steels. Cutting tool steels are primarily used for the fabrication of cutting implements such as lathe tools and milling cutters. Mold steels, on the other hand, are utilized for the creation of various molds, including stamping dies and injection molds. Finally, measuring tool steels are employed in the manufacture of precision measurement instruments like calipers and micrometers.
3. Characteristics and applications of tool steel
Tool steel is widely used in the manufacturing industry due to its high hardness, high wear resistance, good toughness and corrosion resistance. High-speed tool steel, as a typical alloy tool steel, is widely used in manufacturing high-speed cutting tools, drill bits, milling cutters, etc. because of its ability to withstand high temperatures and intense wear caused by high-speed rotating cutting. In addition, mold steel and measuring tool steel also play an irreplaceable role in the manufacturing industry because of their unique properties.
