Slight scale on surface. It is the lowest cost material and best suited for applications that have a protected environment as carbon steel corrodes if not lubricated or atmospherically sealed.

Introduction To Leaf Spring

Then two pieces marked 2 are put together side by side to form another leaf and placed below the top leaf.

Material used for leaf spring. C 0 51 0 59 cr 0 60 0 80 si 1 20 1 60. Good corrosion resistance and electrical conductivity. A leaf spring is a simple form of spring commonly used for the suspension in wheeled vehicles originally called a laminated or carriage spring and sometimes referred to as a semi elliptical spring elliptical spring or cart spring it is one of the oldest forms of springing appearing on carriages in france in the mid 17th century in the form of the two part elbow spring as the illustrated.

General purpose spring wire. The central strip marked 1 is the master leaf which is placed at the top. Answered 2 years ago.

Used for shock loads and moderately elevated temperatures. Laminated leaf spring the lozenge shaped plate is cut into several longitudinal strips as indicated above. Density lb in 3 minimum tensile strength psi x 10 3 modulus elasticity e psi x 10 6 modulus torsion g psi x 10 6 maximum operating temperature.

The material selected was glass fiber reinforced polymer e glass epoxy is used against conventional steel. Cold drawn and heat treated before fabrication. Leaf springs are generally made from high carbon steels with carbon percentage ranging from 0 9 to 1 0.

The automobile industry has great interest for replacement of steel leaf spring with that of composite leaf spring since the composite materials has high strength to weight ratio good corrosion resistance. Oil tempered chrome silicon. Sae 1070 1090 high carbon blue tempered and polished spring steel is a standard material for conventional springs.

However modern day methods have discovered a composite material which is e glass epoxy that can be used as an alternative to steel. Cold drawn and heat treated before fabrication.
