4340 Steel Alloy Tubes: Ultra-Tough, High-Strength Tubes for Demanding Industrial Applications

4340 Steel Alloy Tubes are renowned for their superior mechanical properties, including high tensile strength, impact resistance, and fatigue durability. At Hub Metals and Trading Inc., we supply premium 4340 Steel Alloy Tubes designed for industries demanding structural integrity under extreme conditions, such as aerospace, defense, automotive, oil and gas, and heavy manufacturing.

These heat-treatable steel tubes combine strength and corrosion protection, making them ideal for critical structural components where reliability is essential.

4340 Steel Alloy Tubes are composed of Nickel (1.65-2.00%), Chromium (0.70-0.90%), Molybdenum (0.20-0.30%), Carbon (0.38-0.43%), and trace elements of manganese and silicon. This alloy is known for its heat-treatable properties, allowing it to be quenched and tempered for optimal hardness and performance.

Key Features:

  • Ultra-High Strength: Superior tensile and yield strength for demanding applications.
  • Fatigue Resistance: Withstands cyclic stress and dynamic loads.
  • Heat Treatable: Can be quenched and tempered for increased hardness.
  • Corrosion Protection: Resistant to oxidation and wear with proper treatments.
  • Impact Resistant: Maintains structural integrity under heavy loads.
