Stainless steel spring strip is a cold-rolled stainless steel strip specially used for making springs and elastic elements. It has excellent elasticity, durability, corrosion resistance and mechanical properties, and is widely used in mechanical equipment, automobiles, aerospace, electronic equipment and other fields. Common stainless steel spring strips include 201, 301, 304, 316, 430, 420, 631, etc. Stainless steel spring strip main features are excellent elasticity, excellent durability, and good corrosion resistance.
The thickness of stainless steel spring strip is usually no more than 1. 6 mm and the width is less than 1250 mm. Different states are selected according to customer needs, such as cold-rolled state, solution treatment state or annealed state. In different states, the hardness and cold bending performance of stainless steel spring strip will be different.

Stainless steel spring are available in a variety of materials, including 201, 301, 304, 316, 430, 420, 631, etc. The main features are: excellent elasticity, durability and good corrosion resistance. Stainless steel spring undergo special cold rolling treatment, have good elasticity and toughness, can deform when subjected to external forces, and quickly return to their original state after the external forces are removed. With high tensile strength, fatigue life and corrosion resistance, they are suitable for long-term repeated loads, maintain stable performance in various complex environments, are not easy to rust, and reduce maintenance costs.
Stainless steel spring is typically used for making springs and elastic elements.
Ningbo Huali Steel has introduced advanced machinery from abroad, equipping its production lines with top-tier manufacturing equipment, such as American twenty roll Sendzimir high-precision reversible rolling mill, pulling and straightening machines, continuous bright annealing furnace, steel coil cleaning lines.
