SAE – AISI 1086 (G10860) Carbon Steel – Composition, Properties and Uses

SAE / AISI 1086

AISI 1086 is a high-carbon alloy steel that is widely used in a variety of applications. Thanks to its versatility, durability, and affordability, SAE / AISI 1086 is an ideal material for a wide range of projects. Let’s take a closer look at some of the key benefits of using SAE / AISI 1086.


SAE 1086 is a special type of steel used in applications such as spring productions and chipping tools. It is classified as a medium carbon tool steel which makes it highly durable and capable of withstanding wear, stress, and high temperatures. With an impressive carbon content of 1%, 1086 steel has many other desirable characteristics such as good machinability and weldability. This makes it one of the top choices among manufacturers who are in need of a reliable component material for their products. Its popularity continues to grow due to the strength and reliability it provides in even the most demanding production cycles.

Physical Properties

Alloy 1086 is a medium carbon alloy steel that has been primarily used in applications requiring greater strength and hardness such as shafts, gears, pins, and axle components. Its strength and hardness make it an optimal choice for industries such as construction and energy production. Additionally, SAE/AISI 1086 offers superior workability increasing ductility and weldability, therefore allowing for intricate design possibilities without losing its structural efficacy. Furthermore, these versatile physical properties account for the various uses SAE /AISI 1086 provides such as being utilized in offshore drilling operations and military equipment.

Mechanical Properties

The Grade 1086 grade of steel is an exceptionally tough and durable material, with characteristics that make it ideal for a variety of uses. In terms of mechanical properties, the tensile strength of this grade is 570-725 MegaPascals (MPa), while the yield strength is extremely impressive at 925-1080 MPa. It also has a good rate of elongation, remaining at 45% or higher even at high-stress levels. In addition, this grade exhibits excellent formability, making it perfect for numerous applications from agricultural to mechanical components such as gears and shafts. All in all, these superior physical attributes have made SAE / AISI 1086 a widely used and valued material in many industries.


1086 carbon steel  is a high-carbon alloy steel that can be used in a variety of applications, such as:

  • Automotive parts
  • Construction materials
  • Machinery components
  • Tooling and dies
  • Welding consumables

Corrosion Resistance

One of the most important benefits of using Alloy 1086 steel is its excellent corrosion resistance. Thanks to its high content of chromium and molybdenum, SAE / AISI 1086 is highly resistant to corrosion, even in environments that are highly corrosive. This makes it an ideal material for applications where corrosion resistance is critical, such as in the automotive and construction industries.

Heat Resistance

Another key benefit of using SAE 1086 carbon steel is its heat resistance. Thanks to its high carbon content, SAE / AISI 1086 can withstand high temperatures without losing its strength or becoming brittle. This makes it an ideal material for applications where heat resistance is critical, such as in boiler components and welding consumables.

Heat Treatment

AISI 1086 carbon steel can be heat treated to improve its mechanical properties. Common heat treatment methods include quenching and tempering. Quenching involves heating the material above its critical temperature and then cooling it rapidly in water or oil. This process increases the material’s hardness and strength but decreases its ductility. Tempering involves heating the material to a lower temperature after quenching and then cooling it slowly in the air. This process increases the material’s ductility while sacrificing some of its hardness and strength.


Machining with AISI 1086 steel requires precision and skill. While the unresponsive nature of its low carbon content restricts certain machining operations, such as grinding, it is extremely durable and tolerant of pressure. This makes it a popular choice for many combustion engines due to its ability to maintain structural integrity even in extreme temperatures. It is also ideal for forgings and hammering, a testament to its strength, durability, & stiffness. With experienced machinists at the wheel and appropriate tooling, these properties can be maximized in order to reap the full benefits of SAE/AISI 1086 steel’s mechanical power and characteristics that make it so successful!


The SAE 1086 steel welding process has grown in popularity in the last decade for its efficiency and affordability and for the reliability of the welds it produces. This type of welding is frequently used in applications such as petrochemical refining components, automotive parts, agriculture equipment, and construction supports. It can be done either manually or mechanically with a shielded arc welder to ensure proper depth and penetration of the metal layers being welded and provide greater strength than more traditional welding techniques. To get optimal results with SAE/AISI 1086 welding, one needs to follow the manufacturer’s directions carefully and use high-quality consumables and appropriate shielding gases. With careful attention to detail, anyone from a beginner to an experienced welder can enjoy strong welded joints with this technique.


All in all, SAE / AISI 1086 is an outstanding steel alloy and should be considered for a variety of applications. As it has high strength and ductility, as well as machining flexibility, it can fit into many projects with ease and should be considered. In addition to its great mechanical properties, the alloy also has excellent wear properties and resistance to fatigue, tear and creep. Furthermore, this unique steel needs no heat or other surface treatment since it arrives from the mill ready to use! With so much to offer, SAE / AISI 1086 is an invaluable addition to any project or workshop. Additionally, if you ever find yourself working with this alloy remember that knowledge about its composition, properties and uses are essential for understanding how to make the most out of this incredible material.
