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
