Alloy steel S45C S50C CK45 1.1191

Chemical composition(%):

Available sizes:

Round: Dia. 20 – 1200mm

Flat: Thickness 20 – 120mm, width 305 – 660mm

Plate: Thickness 20 – 400mm, width 1500 - 2300mm

Properties:

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

Heat Treatment:

Soft annealing: heat to 650-700°C, cool slowly.
