1556 spring steel strength, hardness, flexibility and higher than the SUP6 steel hardenability, sensitivity and temper brittleness tendency for overheating, has a tendency to form cracks.

Spring steel 50 crva characteristics and scope of application: the good mechanical properties and process performance, high hardenability, adding vanadium steel grain refinement, reducing heat sensitivity, increase the strength and toughness.

65Mn Spring steel round bar is dedicated to manufacturing various springs and elastic element or similar performance requirements of the main material of structure parts. The following is 65Mn Spring steel round bar detailed informational.

55Si2Mn spring steel silicon and manganese improve flexibility strength and yield ratio, improved hardenability, temper resistance and resistance to relaxation stability, thermal sensitivity is also smaller.
