1045 Steel Machined Parts

Steel 1045

Steel alloy 1045 is a versatile medium carbon alloy, ideal for parts that require strength and impact resistance. Due to its higher carbon content, it has higher tensile strength. 1045 has excellent ductility and toughness.

1045 has a machining cost factor of 3.0 when compared to steel 12L14. It is not ideal for welding or forming due to its higher carbon content. 1045 responds to heat treatment extremely well, but it is not ideal for case hardening.
