Productomschrijving
Cold Drawn Carbon Steel Bar - SAE1020, SAE1045, S45C
AISI 1045 steel round bar is a high carbon steel under American standards, classified as quenching and tempering steel with exceptional strength properties. Available in hot rolled round and square bars, cold-drawn bars, and forged bars, this versatile material serves various industrial applications.
Applications
AISI 1045 round bar is extensively used for manufacturing high-strength moving components including air compressor and pump plungers, rolled shafts, connecting rods, endless screws, gear racks, and heavy machine dowels. In quenching and tempering or normalizing delivery states, it's ideal for wear-resistant parts such as crank axles, machine tool shafts, and transmission shafts after high-frequency quenching or shot peening.
