Spring Steel
Spring steel is engineered for elastic deformation, fatigue resistance, and the ability to return toward its original shape after mechanical loading. It is commonly used for springs, clips, retaining components, washers, and flexible industrial parts requiring controlled strength, resilience, and repeated mechanical performance.
Material overview
Spring steels are selected for applications requiring elastic energy storage, repeated deflection, and resistance to permanent deformation.
Their properties depend on chemical composition, heat treatment, material thickness, and final forming conditions.
Common grades include:
- 51CrV4 / 1.8159: A chromium-vanadium spring steel used for high-performance springs and mechanically loaded components.
- C75S / 1.1248: A carbon spring steel suitable for clips, flat springs, and precision stamped parts.
- 1075: A high-carbon steel used for springs, blades, and flexible mechanical components.
- 1095: A high-carbon steel commonly used for thin spring components and wear-resistant applications.
- 301 Stainless Steel: An austenitic stainless steel used in cold-worked spring temper for corrosion-resistant spring components.
Manufacturing methods include stamping, laser cutting, wire forming, bending, CNC machining, and heat treatment.
Spring performance depends on geometry, operating stress, fatigue cycles, and environmental conditions.
Typical applications include retaining clips, leaf springs, washers, electrical contacts, mechanical fasteners, and industrial spring assemblies.
Buyers should specify the material grade, thickness or wire diameter, required hardness or temper, dimensional tolerances, loading conditions, and production quantity.
Critical applications may require load-deflection testing, fatigue testing, hardness verification, and material certification.
