The specific application and desired properties determine the varying common grades of special steel. Some frequently utilized grades are:
1. Stainless steel, an alloy resistant to corrosion containing a minimum of 10.5% chromium. Grades like 304, 316, and 410 possess exceptional corrosion resistance, high strength, and good formability, making them prevalent in various industries.
2. Tool steel, specifically designed for toolmaking, renowned for its high hardness, wear resistance, and toughness. Common grades such as D2, A2, O1, and S7 possess specific properties suitable for diverse applications.
3. High-speed steel (HSS), a type of tool steel retaining its hardness and cutting ability even at high temperatures. It frequently finds use in cutting tools like drills, end mills, and taps. M2, M35, and M42 are a few well-known HSS grades.
4. Alloy steel, made by incorporating different alloying elements to enhance specific properties. Grades like 4140, 4340, and 8620, known for their high strength, toughness, and wear resistance, are commonly utilized in industries such as automotive, aerospace, and machinery.
5. Spring steel, renowned for its ability to restore its original shape after bending or twisting. Grades like 1095 and 5160 are commonly employed in the manufacturing of springs, suspension components, and hand tools.
These examples merely scratch the surface of the numerous available grades of special steel, each possessing unique properties and applications. It is vital to select the appropriate grade based on the specific requirements of the intended usage.
The common grades of special steel vary depending on the specific application and desired properties. Some of the commonly used grades include:
