Spring steel

Spring steel is used in applications where its elastic properties are the primary function. It is suitable for scenarios with high stress, where the material must return to its original form despite bending or twisting. Spring steel has both high yield strength and tensile strength.

Spring Steel – A Durable Material for Strips, Springs, and Tools

  • Springs

  • Flat bars
  • Flat irons
  • Tools
  • Saw blades
  • Knives

Spring Steel – Properties and Hardening

  • High carbon content ensures high strength.
  • Hardened to maximize properties, reaching up to 60 HRC.
  • Increased brittleness after hardening; bending should be done pre-hardening, though thin materials may be bent post-hardening.
  • Fatigue-resistant applications require high purity and a refined surface finish.
