What is the S45c steel material properties?

S45c steel /CK45 or AISI 1045 is a medium tensile low hardenability carbon steel generally supplied in the cold drawn or turned and polished condition, with a typical tensile strength range 600 – 950 Mpa and Brinell hardness range 179 – 280.

Characterised by good strength and impact properties, with good machinability and reasonable weldability in the as supplied condition.

S45C steel has a low through hardening capability with sections up to around 60mm only generally recommended as suitable for through hardening and tempering. It can however be successfully flame or induction hardened in the as supplied condition resulting in surface hardnesses of up to Rc 54 – Rc 60 depending upon quenching medium employed, type of set up, section size etc.
