PRODUCT DESCRIPTION
ASTM 1045 carbon steel coil is a medium carbon steel product that meets the standards of the American Society for Testing and Materials (ASTM). It is made of high-quality carbon structural steel with a carbon content of about 0.45%. It has good strength, wear resistance and machinability. The coil is formed by hot rolling or cold rolling, with a smooth surface and uniform thickness. The common thickness range is between 0.5 mm and 6 mm. The width can be customized according to customer needs. It is usually supplied in coil form for easy transportation and subsequent processing. Its material properties include high tensile strength (about 620 MPa) and medium hardness (about 170 HB in the unheat-treated state). The mechanical properties can be further improved by heat treatment such as quenching and tempering. It is suitable for manufacturing gears, shafts, connecting rods, tools and other mechanical parts that need to withstand high loads. In terms of processing performance, ASTM 1045 carbon steel coil supports a variety of forming processes such as stamping, bending, welding, and cutting. It is widely used in automobile manufacturing, mechanical equipment, hardware tools and general engineering fields. Our products are strictly quality controlled to ensure that their chemical composition, mechanical properties and dimensional accuracy meet international standards, providing industrial users with cost-effective raw material solutions.

APPLICATION
ASTM 1045 carbon steel coils have become the preferred material for the automotive manufacturing, mechanical equipment, hardware tools and other industries due to their excellent mechanical properties and high cost performance. In the automotive manufacturing field, ASTM 1045 carbon steel coils are widely used in the production of transmission shafts, gear blanks, connecting rods and chassis load-bearing parts. Through quenching and tempering heat treatment, the hardness and fatigue resistance can be significantly improved to meet the stringent requirements of high-load power parts; its tensile strength of up to 620 MPa and uniform thickness accuracy (0.5-6 mm) ensure that the parts are stable and durable in long-term operation. The mechanical equipment industry uses the excellent cutting and welding properties of this material to process bearing seats, hydraulic rods, mold substrates and precision shaft parts, supporting multi-process forming such as turning, stamping, and bending, and adapting to the high-efficiency needs of automated production lines. In the field of hardware tools, ASTM 1045 carbon steel coils are made into high-strength wrenches, tool bases and agricultural machinery accessories through cold rolling process, combined with surface treatment technologies such as galvanizing and blackening to enhance corrosion resistance and extend tool life. In addition, in engineering construction and transportation equipment, this material can be quickly processed into lightweight brackets, connecting plates and fasteners, combining structural strength and economic advantages.
