Expert Spring Steel Prototyping
Spring steel is a low alloy steel with a very high strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting. When the spring steel is in it’s annealed state is has a very soft temper. It is very formable and malleable.
It is important to note that the parts have no spring-like properties until heat treating is completed. In addition to heat treating, spring steel requires plating operations for a finished part.
