One product, a thousand opportunities: choose Erre Inox - Raajratna spring wire 

Stainless steel spring wire is one of the most versatile and reliable materials used in many industries and beyond. Due to its resistance to corrosion and high temperatures, this material offers great design possibilities.

Spring manufacturers are well aware that their processes require precision, durability, and high-quality materials. That's why Erre Inox-Raajratna stainless steel spring wire is an essential element in ensuring high and consistent performance over time.

To meet the specific needs of different applications, stainless steel spring wire is available in a range of diameters (from 0.06 to 22 mm), each suitable for specific production contexts.

Small-diameter wire, for example, boasts low tensile strength and great flexibility, characteristics that make it suitable for precision applications, such as the fabrication of springs intended for watches, medical instruments, and electronic components. It also lends itself to use in the arts, such as in jewelry and goldsmithing, for the manufacture of precious objects.

Larger diameter wire, on the other hand, is mainly used in contexts where greater strength and resistance is required, such as in vehicle suspensions, clamping devices, and heavy industrial applications. Due to its corrosion resistance and durability, it can also be used in aggressive environments such as in the chemical, food, or marine industries.

The products supplied by Erre Inox are manufactured using selected raw materials in the following stainless steel grades: AISI/EN: 302/1.4310, 304/1.4301, 316/1.4401-1.4404 and 631/1.4568. The surface finish can be stearate or polished. The former, being pre-lubricated, facilitates the winding process of the spring, while the latter gives a polished appearance.

The company can supply the following packaging options:

• DIN plastic spools: 100,125, 160, 200, 250, 300 and 355. Weights: 1-40 kg
• Wooden spools: 550 and 760K. Weights: 100-400 kg
• Metal spools: 550 and 760K Weights: 100-400 Kg
• Plastic spools: SH460K/SH390K. Weights: 15-40 Kg
• Coils. Weights: 3-1000 Kg
• Compact coils with cardboard core. 250-1000 Kg

Upon request, nickel-plated wires can also be supplied for diameters from 0.15 to 2.00 mm, as well as Nitronic 50, Inconel X-750, AISI 301 and AISI 904L and subject to NDT with Eddy-Current testing.

In conclusion, choosing Erre Inox stainless steel spring wire means relying on a supplier with well-established know-how and using durable materials that can guarantee long-lasting performance.
