SPRING STEELS
The steels to be used as spring material should be able to get deformed in the elastic area under load pressure, have resistance to breakage and have the capability to get recovered with load removal which means having high ductility. The springiness of the steel material depends on the amount of energy stored during elastic deformation process. The elastic modulus changes at high temperatures with highly alloyed spring steels. Alloying components impart tensile strength, hardness and toughness to the spring steels.
60SiMn5, 55Cr3, 50CrV4 and 60SiCr7 are some examples of spring steels. Spring steels could be produced in standard lengths of 3-6 meter and special sizes in accordance with TS EN 10278 Dimensions and Tolerances Standard.
