Description
Ledeburitic chromium steel with high durability and cutting performance; low distortion on hardening.

Applications
Cutting tools for sheet metal thicknesses up to approximately 2 mm, paper blades,stone compression moulds, section rolling-mill rolls, deep-drawing tools.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 210
Density [g/cm³]: 7.77
Thermal conductivity [W/m.K]: 20.0, 20.5 (at 350^oC), 24.1 (at 700^oC)
Electric resistivity [Ohm mm²/m]: 0.65
Specific heat capacity[J/g.K]: 0.46

Coefficient of Linear Thermal Expansion 10^-6 ^oC^-1

Continuous Cooling Transformation (CCT) Diagram

Soft Annealing
Heat to 800-840^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 255.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650^oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Harden from a temperature of 940-980^oC followed by air,oil quenching or warm bath quenching 500-550^oC. Hardness after quenching is 64 HRC.

Tempering
Tempering temperature: See the data bellow.

Tempering Temperature (^oC) vs. Hardness (HRC)

100^oC	200^oC	300^oC	400^oC	500^oC	600^oC
63	62	60	58	56	48

Forging
Hot forming temperature: 1050-850^oC.

Machinability
The machinability rating of OCR12SP is roughly 20-25% that of free machining carbon steel 1018. Due to its abrasion resistant nature, machining in the hardened condition should be limited to finish grinding.

Forms manufactured: Please see the Dimensional Sales Program.
