Stronger than low-carbon steel with equally good machinability, 1045 carbon steel is widely used for bolts, studs, and shafts.

Containing more carbon than low-carbon steel—but less than 1095 spring steel—1050 spring steel is easily formed into parts such as washers, brackets, and springs before being hardened for use.

These sheets have a softened temper, which is also known as annealed, so they can be easily formed into shape and then heat treated for spring properties.
