SAE1045 Hot Rolled Galvanized Wire

About this product

Hot Rolled Galvanized Wire is a steel wire product manufactured through hot rolling followed by hot-dip galvanizing, providing a durable zinc coating for corrosion resistance. It combines the strength of medium/high-carbon steel with the rust protection of zinc, making it ideal for outdoor and industrial applications.

SAE1045 hot-rolled galvanized wire is a structural steel wire product made of medium carbon steel as the base material, which is made by hot rolling and then galvanizing the surface. Its core structure is a steel core with a carbon content of about 0.45%. This product is widely used in machinery manufacturing, building structures, automotive parts, agricultural equipment, and other fields, and is suitable for environments with high strength, long life, and medium processing requirements.

Feature

High strength bearing capacity

Thanks to the carbon content (about 0.45%) and the grain refinement effect brought by hot rolling, SAE1045 hot-rolled galvanized wire can maintain structural stability when facing tensile and shear loads, with a tensile strength of about 594 MPa and a yield strength of about 554 MPa. It is not easy to deform or break, and is particularly suitable for high-strength load-bearing structural parts such as shafts and pins.

Excellent corrosion resistance

Zinc can form a stable oxide film with oxygen in the air, and has a "sacrificial anode" effect, which can effectively prevent corrosion of the substrate, so that the corrosion resistance of SAE1045 hot-rolled galvanized wire can reach 20-50 years.

Strong processing adaptability

Hot rolling improves the metal structure of the material, making its internal structure denser, which is conducive to improving the stability of subsequent processing. SAE1045 steel has good machinability and medium welding performance and is suitable for various processes such as drawing, stamping, turning, bending, etc.

Excellent heat treatment performance

The SAE1045 hot-rolled galvanized wire can be subjected to a variety of heat treatment methods, such as annealing, normalizing, quenching, and tempering, and its hardness and toughness can be flexibly adjusted according to the conditions of use. After quenching, its surface hardness can be increased to 45-50 HRC, which significantly improves wear resistance and is suitable for use in high-friction environments; after proper tempering treatment, it can reduce brittleness and improve impact toughness.
