ATC601 Material Composition

AATCORP, ATC-601 made by 40Cr material and specialized Quenching and machining technics. It is type of steel often used in components like bushes, especially in heavy machinery and construction equipment like excavators. It's also known as 40Cr steel or Cr40, and is a medium carbon, chromium-alloy steel with properties tailored for strength and wear resistance.

Benefits of ATC601

  • High Hardness:After quenching and tempering, ATC 601 bushes can achieve a hardness between 52 and 60 HRC, providing excellent resistance to wear and abrasion.
  • High Strength & Toughness:ATC601 exhibits good tensile strength (typically 800 - 1100 MPa) and toughness, crucial for applications involving heavy loads and impact.
  • Good Wear Resistance:The combination of high hardness and toughness makes ATC601 suitable for components subject to significant wear, such as bushes in high-friction environments.
  • Moderate Machinability & Weldability:While workable, ATC601 requires careful consideration during machining and welding due to its hardness and potential for cracking during welding. Proper preheating is crucial for welding.
  • Moderate Corrosion Resistance:ATC601 provides fair atmospheric corrosion resistance, but it's not on par with stainless steels, especially in environments with chlorides or acids. It can be susceptible to pitting corrosion in specific conditions.
