Alloy steel is a type of steel that is based on carbon steel and alloyed with various elements such as Si, Mn, W, V, Ti, Cr, Ni, and Mo. These elements can improve the strength, toughness, quenchability, and weldability of the steel. In this article, we’ll take a close look at alloy steel types and uses.
Alloy Steel Types
Alloy steel can be classified based on the content of alloy elements, and in industrial production and daily life, alloy steel is often used in specific industries for specific purposes. Classification based on usage is also common.
Alloy steel types – classified according to the content of alloy elements
- Low alloy steel: the total alloy content is less than 5%;
- Medium alloy steel: alloy content is 5-10%;
- High alloy steel: The total alloy content is higher than 10%.
Alloy steel types – classification by use
- Alloy structural steel: low alloy structural steel (also known as ordinary low alloy steel); alloy carburizing steel, alloy quenched and tempered steel, alloy spring steel; ball bearing steel;
- Alloy tool steel: alloy cutting tool steel (including low alloy cutting tool steel, high-speed steel); alloy mould steel (including cold mould steel, hot mould steel); steel for measuring instruments;
- Special performance steel: stainless steel, heat-resistant steel, wear-resistant steel, etc.
Alloy Steel Uses
Alloy steel is a metal material with excellent performance, widely used in machinery manufacturing, automobile manufacturing, aerospace and other fields. Its main characteristics are high strength, high toughness, high wear resistance and excellent corrosion resistance. Below, the uses of alloy steel will be introduced from different usage perspectives.
The Uses of Alloy Steel in the Machinery Manufacturing Field:
The application of alloy steel in the machinery manufacturing field is very extensive, mainly used for manufacturing heavy-duty mechanical parts and components. For example, buckets, digging teeth of excavators, blade edges of bulldozers, etc. These parts and components need to have high strength and wear resistance to ensure their service life under long-term heavy-duty working conditions. The high strength and wear resistance of alloy steel make it an ideal material for these parts and components.
The Uses of Alloy Steel in the Automotive Manufacturing Field
The application of alloy steel in the automotive manufacturing field is also very extensive. For example, the engine crankshaft, connecting rods, gears, drive shaft, and other components need to have high strength and wear resistance. The high strength and wear resistance of alloy steel make it the preferred material for these parts. In addition, alloy steel can also be used in automobile chassis, suspensions, braking systems, and other components to improve the overall safety performance of the car.
The Uses of Alloy Steel in the Aerospace Industry
The aerospace industry has very high requirements for materials. Alloy steel is widely used in the aerospace industry due to its high strength, high toughness, and excellent corrosion resistance. For example, alloy steel can be used to manufacture aircraft engine blades, high-pressure bearings for aeroengines, springs, nuts, and other components for aerospace applications. In addition, alloy steel can also be used to manufacture the shell and chassis of high-speed aircraft to improve their compressive strength and corrosion resistance.
The Uses of Alloy Steel in the Petrochemical Industry
The application of alloy steel in the petrochemical industry is also very extensive. For example, high-strength and wear-resistant alloy steel is required for the manufacture of oil drill bits. In addition, the manufacture of oil pipelines and petrochemical equipment also requires the use of alloy steel to improve their corrosion resistance and compressive strength, avoiding the risk of pipeline leakage and equipment damage.
