The introduction is as follows
The two digits at the beginning of the number indicate the carbon content of the steel, expressed as a few ten thousandths of the average carbon content, such as the main alloying elements in alloy pipes
Except for a few micro-alloying elements In addition, it is generally expressed in percent. When the average alloy content is used, the steel number
generally only indicates the element symbol and not the content. However, in special cases where confusion is likely to occur, the element symbol may also be marked with a number,
For example The steel number and the chromium content of the former are , and the latter is , and the other ingredients are all the same.
When the average content of alloy elements is ,, the content should be indicated after the element symbol, which can be expressed as
,, etc. For example.
The vanadium, titanium, aluminum, boron, rare earth and other alloying elements in steel are all micro-alloying elements. Although the content is very low, they should still be marked in the steel grade.
For example, in steel. Vanadium is, boron is.
Grade high-quality steel should be added at the end of the steel number to distinguish it from general high-quality steel.
For alloy structural steel used for doors, the steel number is preceded (or suffixed) with a symbol representing the purpose of the steel type. For example, steel for rivet screws,
