Characteristics and application examples:

High strength, good machinability, cold deformation capacity moderate, poor welding, no temper brittleness, hardenability is low, easy unboiled water quenching cracks, mostly in the use of quenched and tempered or normalized state, similar to the overall performance of both surface after quenching can be used to manufacture parts to withstand greater stress. Suitable for the manufacture of the crankshaft when the mandrel. Driveshaft. Piston connecting rod. Sprocket gear, etc., need to be preheated for welding parts. Slow cooling after welding.
