Description
1045 is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned, ground and polished.

Applications
Component parts for vechiles, shafts, bushings, crankshafts, connecting rods and parts for the machine building industry and steel for axes, knives, hammers, etc.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 190-210
Density [g/cm3]: 7.84
Thermal conductivity [W/m.K]: 15.1

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

20-100oC	20-200oC	20-300oC	20-400oC	20-500oC	20-600oC	20-700oC
11.6	12.3	13.1	13.7	14.2	14.7	15.1

Soft Annealing
Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 207.

Hardening
Harden from a temperature of 820-850oC, 830-860oC followed by water or oil quenching.

Normalizing
Normalizing temperature (oC): 840-870oC.

Tempering
Tempering temperature: See the data bellow.
