With more than thirty years of dedicated expertise, it has consistently excelled in the precision crafting of seamless steel tubes and pipes.

Product Description

    Chromium is one of the main alloying elements in heat-resistant steel. Chromium steel refers to alloy steel containing chromium, which has a hard texture, is wear-resistant, corrosion-resistant, does not rust, and can be used to manufacture machines and tools. Has high oxidation resistance and corrosion resistance. For different usage environments, other elements such as molybdenum, vanadium, tungsten, titanium, niobium, boron, etc. are often added. Common application areas and steel grades include 12CrMo (high and medium pressure steam ducts), 20CrMo (blades), 35CrMo (parts used for a long time below 650 ºC), 1Cr5Mo (reheaters below 650 ºC and petrochemical equipment with strong corrosion resistance below 550 ºC), and 1Cr12Mo (blades below 450 ºC)
   In the realm of automotive and motorcycle manufacturing, the use of chromium molybdenum steel pipes is predominantly seen in frame production, offering remarkable benefits like lightweight, high strength, and excellent resistance to corrosion.
The piston pins inside the engine also use 20Cr or 20CrMo

Simultaneously, these superior chromium molybdenum steel pipes find extensive applications in oil wells and heat exchange equipment, thanks to their exceptional properties, including resistance to high temperatures, high pressures, and corrosion.
