AISI 1005 Steel Chemical Properties

The chemical composition of SAE Steel 1005 consists mostly of iron with trace amounts of carbon—usually no more than 0.25%. This low carbon content makes it ideal for applications such as springs or wires where strength isn’t a major concern, but low weight is important.

SAE – AISI 1005 Steel Physical Properties

AISI 1005 has a density of 7.8g/cm3 (0.278 lb/in3). Its melting temperature is 1280°C (2336°F), and its thermal conductivity is 31 W/(mK). UNS G10050 also has a modulus of elasticity of 200 GPa (29 million psi) and an electrical resistivity of 0.14 μΩ·m at 20°C (68°F).

SAE 1005 Steel Mechanical Properties

AISI 1005 Steel has good mechanical properties, including a yield strength ranging from 280 to 380 MPa (41 to 55 ksi), an ultimate tensile strength between 310 to 430 MPa (45 to 62 ksi), and an elongation rate between 30% to 40%. AISI steel 1005 also has good fatigue characteristics with an endurance limit of around 180 MPa (26 ksi).

SAE – AISI 1005 Steel Equivalent

Other designations that are equivalent to the AISI 1005 carbon steel include the following:

SAE – AISI UNS G10050 Steel Uses

Due to its excellent mechanical properties, weldability, and corrosion resistance, G10050 can be found in many automotive components, such as transmission shafts, drive shafts, axles, suspension components, and steering columns. Due to its high wear resistance, it’s also used in industrial applications like piping systems or tooling equipment.

Corrosion Resistance & Heat Treatment

When exposed to atmospheric conditions or other corrosive environments, such as salt water or acidic liquids, the rust-resistant qualities of SAE 1005 Steel make it ideal for outdoor applications like bridges or outdoor furniture where corrosion protection is needed. Heat treatment will increase the hardness level but should only be done when necessary due to the risk of cracking or warping the metal; when heat treated correctly, however, UNS G10050 can reach Rockwell hardness levels up to 50 HRC without any adverse effects on the material.

Conclusion

In summary, SAE/AISI1005 steel offers excellent strength with decent weldability and corrosion resistance at an affordable price point, making it perfect for automotive parts such as suspension components and drive shafts along with industrial applications like tooling equipment or piping systems that require durability over time without breaking your budget. Its low carbon content also makes it great for applications where lightweight but still strong materials are preferred, such as springs or wires, which need flexibility but still need some strength. With proper heat treatment, this alloy can even reach Rockwell hardness levels up to 50 HRC while still maintaining all its original qualities intact, making it one of the most versatile alloys available today!
