AISI 1045 carbon steel plate is a versatile medium carbon engineering steel that can be through hardened to about 2.5” (63mm), as well as being flame or induction hardened to Rc58. AISI 1045 alloy steel plate can be readily welded and machined providing correct procedures are followed.
AISI 1045 alloy steel plate is a medium carbon, medium tensile steel supplied as forged or normalized. This steel shows good strength, toughness and wear resistance. 1045 alloy steel plate will through harden to 2.5” (63mm) with a tensile strength of 66 – 120 Ksi (620 – 850 MPa).
