12cr1movG Alloy tube
The 12Cr1MoV alloy tube is based on high-quality carbon structural steel, and one or several alloying elements are appropriately added to improve the mechanical properties, toughness and hardenability of the steel. Therefore, depending on the chemical composition (mainly carbon content), heat treatment process and use, such steel can be roughly divided into three types: carburizing, quenching and tempering steel.
Chemical Composition of 12cr1movG Steel
C: 0.08-0.15
Si: 0.17-0.37
Mn: 0.40-0.70
Mo: 0.25-0.35
Cr: 0.90-1.20
V: 0.15-0.30
Alloy tube Representation method
1, The two digits at the beginning of the steel number indicate the carbon content of the steel, expressed as a few tenths of the average carbon content, such as 40Cr.
2, Advanced high-quality steel should be added "A" at the end of the steel to distinguish it from ordinary high-quality steel.
3, Special purpose alloy structural steel, steel crown (or suffix) represents the symbol for the use of the steel. For example, 30CrMnSi steel for rivet screw, steel number is expressed as ML30CrMnSi.
