SAE – AISI 1080 Steel (UNS G10800) – Composition, Properties and Uses

SAE / AISI 1080 Steel

SAE/AISI 1080 steel is a versatile alloy that can be used for a variety of applications. The main reason for its popularity is its high resistance to corrosion. In addition, 1080 steel has a good heat resistance and can be heat treated for additional hardness and strength. Here are some of the most common uses for 1080 steel.

SAE-AISI 1080 Composition

Grade 1080 steel is an alloy made from iron and carbon. The main elements that make up this alloy are iron (Fe), carbon (C), manganese (Mn), sulfur (S), phosphorus (P), and silicon (Si). Other trace elements may also be present depending on the grade of 1080 steel being used. In general, 1080 steel has a higher carbon content than other types of steel, which helps to increase its hardness and strength while maintaining its ductility.

Element Content (%)
Iron, Fe 98.0 – 99.0
Carbon, C 0.75 – 0.88
Manganese, Mn 0.60 – 0.90
Sulfur, S 0.05 (max)
Phosphorous, P 0.04 (max)

SAE-AISI 1080 Chemical Properties

The chemical properties of alloy 1080 steel makes it ideal for use in many applications due to its ability to resist corrosion and wear. It has a high chromium content which helps it to resist corrosion from acids, alkalis, and organic compounds as well as saltwater spray. The silicon content also helps increase its ability to resist corrosion from oxidation or rusting when exposed to air or moisture for long periods. This makes it suitable for use in environments with high levels of humidity or water, such as marine applications.

SAE-AISI 1080 Physical Properties

Grade 1080 carbon steel is an incredibly strong metal option, boasting impressive physical properties for a wide variety of applications. Not only is 1080 steel highly resistant to wear and fatigue, but its tensile strength gives it superior fracture toughness when exposed to shock or vibration. A further benefit of incorporating 1080 steel into your designs lies in its low carbon content and simple heat treatment, resulting in improved weldability and fabrication characteristics. Whether you need to build a bridge or need something tough enough to hold up under extreme stress, 1080 steel has the capabilities necessary to complete the job.

SAE-AISI 1080 Mechanical Properties

Alloy 1080 carbon steel has a very high tensile strength ranging from 1200-1400 MPa, depending on the grade used. It also has excellent ductility, which allows it to be drawn into thin wires without breaking or deforming. The yield strength is also very good, which means it can withstand large amounts of force without permanently deforming or failing under load. It has good fatigue strength, which means it can withstand repeated loading and unloading cycles without cracking or breaking over time. Finally, it has excellent wear resistance, which makes it suitable for use in abrasive environments where other materials would quickly wear out or fail under load due to friction between moving parts such as gears and bearings in machinery.
