Carbon Steel AISI 1045 Angle is a medium carbon steel that stands out for its impressive strength, hardness, and wear resistance, making it a go-to choice for heavy-duty structural and engineering projects. Shalan Steel, a well-respected manufacturer and supplier located in Kuala Lumpur, Malaysia, offers top-notch AISI 1045 angle bars in a variety of sizes and thicknesses. These angle sections are commonly utilized throughout Malaysia and Southeast Asia for structural supports, frames, brackets, and load-bearing applications in both construction and machinery.
With a carbon content of about 0.43–0.50% and manganese ranging from 0.60–0.90%, AISI 1045 delivers excellent tensile strength between 570 to 700 MPa and a yield strength of around 300 to 450 MPa. This steel can be heat-treated to further improve its mechanical properties, including through hardening and tempering. Compared to lower carbon grades, 1045 angles provide enhanced strength and wear resistance while still maintaining decent machinability and weldability when preheated correctly.
