Carbon Steel SAE1055

Carbon Steel SAE1055 is a medium-to-high carbon steel alloy that contains roughly 0.55% carbon, along with other elements including manganese, silicon, and phosphorus. It is commonly used in the manufacturing of machine parts, blades, springs, and gears due to its high strength, toughness, and wear resistance. It is also utilized in the construction of some types of hand tools, agricultural equipment, and automotive parts. SAE1055 is known for its ability to be easily machined and welded, making it a versatile material for a variety of applications.

Here are some of the key specifications of this material:

1. Chemical composition - Carbon Steel SAE1055 has a carbon content between 0.50-0.60%, manganese content between 0.60-0.90%, phosphorus and sulfur contents less than 0.050%. These chemical properties contribute to its strength, toughness, and durability.

2. Mechanical properties - With a tensile strength of 650-800 MPa and a yield strength of 450 MPa, Carbon Steel SAE1055 is a high-strength material that can withstand high stress applications. Its toughness and ductility make it a popular material for use in mechanical components.

3. Surface finish -  available in different surface finishes, including hot rolled, cold rolled, and annealed. These finishes provide different levels of surface quality and are suitable for different applications.

4. Applications - commonly used in the manufacturing of cutting tools, springs, saw blades, and other mechanical components. It is also used in the automotive and construction industries for its strength and durability.
