Castle Metals distributes a wide range of Alloy 1045 in rounds, squares, and hexs from our distribution centers in the U.S., Canada, Mexico, Shanghai, Singapore, France, and the U.K. When customers confer with us on 1045, sometimes they say they are stressed by supporting growth. Should we decide it makes sense, Castle can leverage its supply network to allow our customers to achieve their plans.
Carbon 1045 is a higher strength alternative to 1018, as a result of the higher carbon content. It is the most popular medium carbon steel. It is very popular for shafts and gears. It has moderate ductility and weldability.
