86L20 Alloy Steel

86L20 alloy steel, a triple alloy carburizing steel offering good ductility and durability. It has contained levels of molybdenum and chromium which give exceptional wear resistance and hardness.

This alloy steel grade is one of carburizing alloys mostly used for its strong tough core and high case hardness. The added lead content “L” plays significantly in adding a great finish, machinability, and tool life – it also boosts part production up to 25 percent. Heat treating procedures are used to help it achieve case depth and optimal hardness.

The additional lead content grants it with an improved machinability. In addition, the material is also alloyed with nickel which imparts ductility and good toughness while the molybdenum and chromium increase wearability and hardness penetration. The alloyed elements result in a production of high case hardening and strong tough core.

86L20 alloy also exhibits good welding qualities. The advantage as a leaded alloy steel grade, it would not take to sacrifice other desirable properties to improve machinability. However, it is not advisable to use the material for applications over 400o F since its ductility is low at elevated temperatures.

This leaded alloy steel grade can be great in many applications which include:

• Spline shafts
• Oil pump jigs
• Pinions
• Gauges
• Plastic molds
• Crankshafts
• Gears
• Ring gears
