The 20Cr alloy steel round bar is a top-notch, low carbon, low alloy steel that is enriched with chromium, molybdenum, and nickel, making it suitable for case hardening processes. Once subjected to an oil quenching and tempering process, the 20Cr alloy steel round bar achieves a hardness level of 28-34 HRc. The more limited range of carbon content in the 20Cr alloy steel round bar enhances its weldability, allowing it to be easily cut into multiple pieces of varying lengths. Grinding the tool steel bar is also an option, which results in a high-precision quality finished bar with extremely tight tolerances. The data provided serves as a great resource for industry professionals seeking a robust alloy material with excellent properties, allowing them to conduct their activities with reliability and confidence.

3. Service Provide:Cutting/Packing
We offer two techniques for our product: Annealed or Quenched and Tempered. You can choose to have your product processed through either technique depending on your desired outcome. Annealing involves heating the material to a specific temperature and cooling it slowly to evenly distribute any internal stresses within the material. Quenching and Tempering, on the other hand, involves heating the material to a high temperature and rapidly cooling it to obtain a hard, strong, and durable product. The product is then tempered to reduce brittleness and improve its toughness. Both techniques have their specific benefits, and we can help you select the most appropriate one for your project.
