Yes. Originally, bumpers were merely designed to protect the vehicle from damage. Today, bumpers are designed as part of the shock absorbing system of a car.
Bumpers were created when it became apparent for the need to protect the newly created automobile from low speed accidents. The bumper is there to protect the vehicle from accidents that do not exceed speeds of 25-45 miles per hour.
Clio bumpers are placed onto a Renault Clio, a type of super minicar. The bumpers are placed in the front and back and help protect the car to an extent.

Head bumpers to protect their heads, Shiping boots to protect their legs, Tail wraps, Body blankets.
Iron, Chromium, Nickel, Steel, Nitrogen, and Molybdenum Iron is the main element of stainless steel, Chromium is a metal that stalls the oxidization of iron. Nickel increases the corrosive resistance further and can protect stainless steel from rough usage and harsh environmental conditions. Pitting or scarring is avoided by adding molybdenum to steel.
For along time bumpers have been made to protect the bodywork of a car in the event of low speed collision, such as at stops or traffic lights. Bumpers are relatively cheap compared to body sections of cars, and often prevent a lot of body damage. In a high speed collision it doesn't matter whether you have bumpers or not, lots of bodywork will be wrecked.
Bumpers are installed on automobiles as a safety feature. They are actually used more to protect pedestrians that may be hit, rather than occupants of a car in a collision, although they are also of some us in protecting the car's safety systems.

Bumpers and softer material deforms when force is applied. If they deform, they absorb some energy. When you hit a wall or a car, a bumper absorbs a part of the energy when you hit the wall. In some cases that difference sames a mans life.
Stainless steal is a mixture of carbon (2%) atoms and chromium (13%) and steel (85%). Stainless steal is more brittle than other metals because of the high carbon content. Chromium helps protect the steel from rust.
