25Cr2MoVA hot rolled steel sheet information
① The two digits at the beginning of the steel number indicate the carbon content of the steel, expressed in ten-thousandths of the average carbon content, such as 40Cr, 25Cr2MoVA alloy tube
②The main alloying elements in steel, except for individual microalloying elements, are generally expressed in a few percent. When the average alloy content is less than 1.5%, generally only the element symbol is indicated in the steel number, and the content is not indicated. However, in special circumstances, it is easy to cause confusion, and the number "1" can also be marked after the element symbol, such as steel number "12CrMoV" and "12Cr1MoV", the former has a chromium content of 0.4-0.6%, the latter has a chromium content of 0.9-1.2%, and the rest are all the same. When the average content of alloying elements is ≥1.5%, ≥2.5%, ≥3.5%..., the content should be indicated after the element symbol, which can be expressed as 2, 3, 4... etc. For example, 18Cr2Ni4WA.
③ Alloying elements such as vanadium V, titanium Ti, aluminum AL, boron B, and rare earth RE in steel are all microalloying elements. Although the content is very low, they should still be marked in the steel number. For example, in 20MnVB steel. Vanadium is 0.07-0.12%, and boron is 0.001-0.005%.
④High-grade high-quality steel should add "A" at the end of the steel number to distinguish it from general high-quality steel.
⑤ Special purpose alloy structural steel, the steel number is prefixed (or suffixed) with the symbol representing the purpose of the steel. For example, 30CrMnSi steel special for riveting screws, the steel number is expressed as ML30CrMnSi.
Alloy pipes and seamless pipes are both related and different, and should not be confused.
Alloy pipe is defined by steel pipe according to the production material (that is, material), as the name implies, is pipe made of alloy; while seamless pipe is defined by steel pipe according to the production process (seamless and seamless), the difference from seamless pipe is Seam pipes, including straight seam welded pipes and spiral pipes.
