86L20 STEEL BAR STOCK

Extremely Strong and Durable 86L20 Steel Bar Stock

86L20 steel bar stock is a low-carbon nickel-chromium-molybdenum alloy steel known for its excellent carburizing properties. This grade delivers a unique combination of high surface hardness, case toughness, and core strength, making it ideal for demanding applications such as gears, shafts, and pinions.

Mechanical Properties of 86L20 Steel

  • Tensile Strength: 75–95 ksi
  • Yield Strength: 50–80 ksi
  • Elongation (in 2”): 17–35%
  • Case Hardness: Excellent carbide formation ensures superior wear resistance
  • Toughness: Above-average core toughness with shock resistance

Key Benefits

  • Carburized Performance – Maintains a hard surface layer while keeping a ductile, strong core.
  • Wear Resistance – Carbide formation improves hardness and extends part life in heavy-duty applications.
  • Temperature Resistance – Performs well under both high and low temperature conditions.
  • Durability – Combines strength and toughness, ensuring reliability in industrial environments.

Common Applications of 86L20 Bar Stock

Thanks to its strength and toughness, 86L20 steel is widely used in:

  • Gears and gear shafts
  • Pinions and drive components
  • High-strength shafts
  • Heavy-duty machinery parts

While stainless steel is often considered more ductile, 86L20 carbon alloy steel delivers extreme strength, durability, and shock resistance—making it one of the most dependable choices for machinery and industrial applications.
