About AISI 4140 Seamless Pipes — Grade, Equivalents & Properties

AISI 4140 is a low-alloy steel containing chromium (~0.90–1.20%) and molybdenum (~0.15–0.25%), which significantly enhance its hardenability, tensile strength, and resistance to wear and fatigue. It is one of the most widely used mechanical tubing grades for heavy engineering, oil & gas tooling, cylinder manufacturing, and structural applications.

Key international equivalents of AISI 4140:

  • 42CrMo4 —  EN 10083-3 (European Standard)
  • 7225 —  DIN Material Number
  • SCM440 —  JIS G4053 (Japanese Standard)
  • EN 19 —  British Standard
  • 708M40 —  BS970 (UK)

In Kerala, AISI 4140 seamless pipes and mechanical tubes are also commonly referred to as 4140 alloy pipe, CrMo pipe, chromoly tube, alloy steel cylinder pipe, or high-strength alloy tube — particularly in the heavy engineering and fabrication sectors around Kochi, Thrissur, and Palakkad.
