1045 Hot Rolled

Alro stocks 1045 Steel Plate. 1045 is a medium carbon steel used extensively in induction hardening applications. 1045 is not normally considered a screw machine steel and is only fair for brazing and welding. However, it can be forged satisfactorily and is the most common shafting steel in the medium carbon range.

About C1045 HR (Hot Rolled)

C1045 is a work hardening steel. 1045 steel is silicon killed with a higher carbon content for greater strength. Strength can be improved in the lighter and medium thickness by heat treatment. Machinability is good, while forming and welding properites are limited.
