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
