4340 Steel Alloy Forgings

4340 Steel Alloy Forgings: Ultra-High Strength, Wear-Resistant Steel for Industrial Excellence

4340 Steel Alloy Forgings are a nickel-chromium-molybdenum steel alloy known for their superior tensile strength, impact resistance, and exceptional toughness. These properties make them ideal for demanding industrial applications where mechanical integrity and long-term performance are critical. At Hub Metals and Trading Inc., we supply premium 4340 Steel Alloy Forgings for industries including aerospace, defense, automotive, oil and gas, and construction.

These heat-treatable forgings are designed for components requiring maximum durability, fatigue resistance, and wear protection.

4340 Steel Alloy Forgings are composed of Nickel (1.65-2.00%), Chromium (0.70-0.90%), Molybdenum (0.20-0.30%), and Carbon (0.38-0.43%), with trace amounts of manganese and silicon. This heat-treatable alloy offers exceptional mechanical properties, particularly when quenched and tempered for enhanced hardness and durability.

Key Features:

  • Ultra-High Strength: Exceptional tensile and yield strength for structural integrity.
  • Fatigue Resistant: Withstands cyclic stress and repetitive loading.
  • Heat Treatable: Enhanced hardness with quenching and tempering processes.
  • Impact Resistant: High fracture toughness for critical applications.
  • Wear Protection: Excellent surface hardness for abrasion resistance.
