Description
CK55 steel has a higher (0.55%) carbon content for greater strength than the lower carbon alloys. It is hardenable by heat treatment, quench and tempering.
Applications
Steel for springs, for quenched and tempered springs, for surface hardened products like shafts, bushings, crankshafts, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Soft Annealing
Hardness after soft annealing is 229 HB.
Normalizing
Normalizing temperature: 825-865oC.
Hardening
Harden from a temperature of 840-870oC, 850-880oC followed by water or oil quenching.
Tempering
Tempering from the quenched condition may be done at 540-680oC depending upon the strength desired.

Hardenability Diagram
Diagram Tempering Temperature – Mechanical Properties
Forging
Hot forming temperature: 1100-850oC.
Machinability
Machinability is good, rated at 50% that of the AISI 1112 alloy used as a 100% machining rated steel.
Corrosion Resistance
This is a steel alloy and will rust if not protected. it is not corrosion resistant.
Welding
CK55 steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at 150 to 260oC and post-heat at 590 to 650oC practice per an approved welding procedure.
Cold working
In the annealed state the CK55 alloy is readily cold worked by conventional methods.
