Spring steels: elasticity and tensile strength

Spring steels are designed to offer exceptional fatigue resistance and a long service life, even under cyclic mechanical stresses.

Thanks to their chemical composition and good workability, these steels are ideal for fabricating springs, straps and elastic components for use in automotive, industrial and precision engineering applications.

50CrV4 - 1.8159 steel

50CrV4 – 1.8159 steel is a spring steel alloyed with chrome and vanadium per EN ISO standards, known for its excellent elasticity and resistance to dynamic fatigue.

55Si7 - 1.0904 steel

55Si7 – 1.0904 steel is a spring steel alloyed with silicon per EN ISO standards, known for its high elasticity and resistance to permanent deformation.

60Si7 - 1.0906 steel

60Si7 – 1.0906 steel is a spring steel alloyed with silicon per EN ISO standards, with a high elastic limit and resistance to fatigue.

52SiCrNi5 - 1.7117 steel

52SiCrNi5 – 1.7117 steel is a spring steel alloyed with silicon, chrome and nickel per EN ISO standards, known for its excellent combination of elasticity, fatigue resistance and tenacity.
