Spring Steel Strip

If you look up definitions of spring steel, you are likely to find the following:-

From Wikipedia

Spring steel is a low alloy, medium carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting.

From AboutMetals

The steels used for spring making depend on the application and type of spring. They range from plain carbon grades in the range 0.5% to 1.00% C. to Chromium, Chromium-Vanadium, Nickel-Chromium-Molybdenum, Silico- Manganese and Silicon-Manganese-Chromium-Molybdenum types. Full details can be found in BS5770.

From

thefreedictionary

A variety of steel, elastic, strong, and tough, rolled for springs, etc.

In summary spring steels are medium to high carbon steels that are able to be heat treated to achieve high yield strengths with the ability to return to their shape after mechanical deformation. Spring steels are used in a huge variety of applications and the springs made from them are found in objects all around us. Indeed it would be difficult to operate without spring steel when you consider that play a key role in the operation of everything from the stapler on your desk to the clutch in your car.

Whilst any steel with a carbon content above 0.50% can be considered a spring steel, the most used grades contain from 0.70% to 1.00% carbon and for more critical applications, further alloying elements such as chromium and vanadium.

As we build up this new site, we will go on to examine the various national and international standards and look more closely at production and applications.
