Available sizes
Round: Dia. 60300mm
Plate: Thickness 16 300mm, width 60- 520mm
Delivery condition: Hot rolled or forged Peeled or black surface, annealed or no heat treatment.

Properties:
A medium carbon steel is used when greater strength and hardness is desired than in the â??as rolledâ?� 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.
Hardness after annealing: Max. 207 HB
Hardening: 820 - 850 °C
Normalizing temperature: 840-870°C
Hardness after tempering:
