– Elongation: 15-18%
– Hardness: 230-280 HB

Technical properties:
– Good machinability
– Good weldability
– Good cold and hot forming properties

Chemical composition:
– Carbon (C): 0.36-0.44%
– Silicon (Si): 0.10-0.35%
– Manganese (Mn): 0.50-0.80%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.040% max
– Chromium (Cr): 0.60-1.00%
– Nickel (Ni): 1.30-1.70%
