What are ASTM A519 Grade 4140 Tubes?

ASTM A519 Grade 4140 tubes are seamless mechanical tubing products manufactured from medium-carbon chromium-molybdenum alloy steel. The addition of chromium and molybdenum significantly improves hardenability, strength, wear resistance, and fatigue performance compared to conventional carbon steel grades.

The material is internationally recognized under several designations including:

  • ASTM A519 Grade 4140
  • AISI 4140
  • SAE 4140
  • UNS G41400
  • EN 1.7225
  • 42CrMo4 (Equivalent Grade)

Due to their excellent mechanical properties, ASTM A519 Grade 4140 seamless tubing products are preferred in applications requiring high strength under dynamic loading conditions.
