12Cr1MoVG a material 12Cr1MoVg alloy tube alloy tube. The main purpose is for the production of boiler steel structure, use temperature of 580 ℃, requires a higher temperature steel lasting strength, normalized and tempered steel to delivery. 12Cr1MoVg alloy tube is based on high-quality carbon structural steel 15crmog small-diameter pipe, due to join one or more of the alloying elements used to improve the mechanical properties of steel, toughness and hardenability. With such a steel product, usually subject to heat treatment (normalizing or quenching); which is made of parts and components prior to use, usually subject to quenching or surface chemical treatment (carburizing, nitriding, etc.), surface hardening or induction hardening processing. Thus, according to the chemical composition (mainly carbon content), and the use of different heat treatment process, such steels can be divided roughly carburizing, quenching and nitriding steel three. 12Cr1MoVG alloy steel pipe representation ① beginning of the two-digit number of the carbon content of steel, the average carbon content of the very few that, as 40Cr. ② major alloying elements in steel, in addition to individual micro-alloying elements q235b small-diameter steel pipe, usually a few percent. When the average alloy content <1.5%, steel elements generally marked only symbols, not marked content, but prone to cause confusion in exceptional circumstances, after the element symbol can also be marked with the number '1', for example steel '12CrMoV' and '12Cr1MoV', the former chromium content of 0.4-0.6%, which is 0.9 to 1.2% of small-diameter steel pipe, the remaining ingredients are all the same. When the average content of alloying elements ≥1.5%, ≥2.5%, while ≥3.5% ......, in the back of the element symbols should be marked content, can be expressed as the corresponding 2,3,4 ...... etc. For example 18Cr2Ni4WA. ③ vanadium steel V, Ti Ti, Al AL, boron B, rare earth RE alloying elements q345b small-diameter steel pipe, are micro-alloying elements, although very low levels, should bid out in steel. For example 20MnVB steel. Vanadium 0.07 to 0.12%, boron of 0.001 to 0.005%. ④ High quality steel should finally add 'A' in the steel, as distinct from the general high quality steel.
