1045 S45c Low Carbon Steel Round Bar Structual Steel Bar Hot Rolled
AISI 1045 steel / JIS S45C / DIN CK45 Carbon steels also called carbon element. They are a category of steels with 0.12 to 2% carbon composition. AISI 1045 steel is a kind of medium carbon steel design need more intensity and hardness can function. The steel has excellent dimensional accuracy, concentricity and straightness, common to reduce wear in high speed applications. it can form turned, ground and polished, can be processing asymmetric finite deformation.
SAE-AISI 1045 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1045 is the designation in both the SAE and AISI systems for this material. G10450 is the UNS number. It can have a moderately high tensile strength among the wrought carbon or non-alloy steels in the database. The properties of SAE-AISI 1045 steel include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare SAE-AISI 1045 steel to: wrought carbon or non-alloy steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
Product Applications
Hot rolled SAE-AISI 1045 is SAE-AISI 1045 steel in the hot worked condition. It has the lowest strength and highest ductility compared to the other variants of SAE-AISI 1045 steel. The graph bars on the material properties cards below compare hot rolled SAE-AISI 1045 to: wrought carbon or non-alloy steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
