Alloy steel mainly includes copper, manganese, aluminum, titanium, rare earth and other materials, but does not include carbon and iron. The steel is a high-strength steel composed of ordinary carbon steel and appropriate alloying elements. Due to the different elements added, the appropriate treatment method is adopted, and it has good anti-corrosion, high and low temperature, wear-resistant and non-magnetic characteristics, so the service life is longer.

However, because of its welding difficulties, production costs and expenses will be affected. The bond of glue is very difficult, and it needs to be welded so that it can be used normally. The alloy steel is mainly composed of niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, silicon, manganese, chromium, nickel and molybdenum. Among these carbides, vanadium, titanium, niobium, zirconium, etc. are strong carbides that constitute steel. Under certain conditions, as long as the carbon content is sufficient, they will generate carbides under certain conditions. Aluminum, copper, nickel, cobalt, silicon, etc. are elements that cannot form carbides, usually in the form of atoms in solids.

Alloy steel according to its different composition, can be divided into: low alloy steel, medium alloy steel, high alloy steel. According to the composition of alloy steel, it can be divided into chromium steel, manganese steel, chromium manganese steel, chromium nickel steel and so on.

According to the classification of alloy composition, the total content of less than 5% is low alloy steel alloy; The total amount of alloying elements is 5% to 10% is medium alloy steel; The total amount of alloying elements in high alloy steel is more than 10%.

The use of alloy steel

1. When alloy steel is used to make a machine, the service life of the machine can be extended.

2. alloy steel will also be used in building construction, so it is widely used.

3. alloy steel in daily life is also often used to make some commonly used tools.

4. alloy spring steel and rolling bearing steel, I think everyone should know, because we often encounter this alloy.

5. alloy steel there are some special alloys, such as permanent magnetic steel, non-magnetic steel, soft magnetic steel, etc., because of their different uses, the price will also be very different.
