Assuming Leaf Springs, the most common spring type used is Automobiles:-


1) Carbon Steel 98 C4(SAE 1095), properly heat treated is used for laminated springs

2) Silicon-manganese steels, 50C9(SAE 9250) and 60C9(SAE 9260), the latter having higher C content and higher mechanical properties, are both standardized for leaf springs.

3) Chrome-vanadium steel has greater strength, toughness and resistance to failure through repeated stresses.

For automotive springs,

  • electrocoating is used for lower-cost applications.
  • For higher performance applications, powder coating is used either as a thick single layer, or as a topcoat over an electrocoating basecoat.

Now a days the trend is to use the light weighting of vehicles and one of the part which can be done to achieve this is reducing weight of suspension system. so below materials are used for this.

  • carbon-fiber reinforced plastics (CFRP)and
  • glass reinforced plastics (GRP)
