Classification of alloy steel?

1. Divided by alloy element content

1) Low alloy 5%;

2) The total content of alloy elements in medium alloy steel ranges from 5% to 10%;

3) The total alloy content of high alloy steel is greater than or equal to 10%;

2. According to the type of alloy element

There are chromium steel, manganese steel, chromium manganese steel, chromium nickel steel, chromium nickel molybdenum steel, silicon manganese molybdenum vanadium steel, etc.

3. Classified by main purpose

(1) Structural steel

1) Structural steel used in construction and engineering

2) Structural steel for mechanical manufacturing

(2) Tool steel

(3) Special performance steel

There are many types of alloy steel, usually classified as low alloy steel based on the content of alloying elements (content)

Lt5%~10% gt10%; Classified by quality into high-quality alloy steel and special alloy steel; According to their characteristics and uses, they are divided into alloy structural steel, stainless steel, acid resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel, and special performance steel (such as soft magnetic steel, permanent magnetic steel, and non magnetic steel).
