Price:
R.F.Q.
AISI 1045 is a medium carbon steel valued for its strength, toughness, and machinability. With a carbon content of approximately 0.45%, it offers good tensile strength and hardness, making it suitable for shafts, gears, axles, bolts, and machinery components. It can be easily machined and welded, and further heat treatment enhances its mechanical properties, making it versatile across various industries. We import from Europe, Japan and China.
