i want for an exercise to find the materials for a supsension car system and manufacturing
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,
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.
