Stainless Steel 316L Electropolished Compression Spring for Pharmaceutical and Food Processing Equipment

The Stainless Steel 316L Electropolished Compression Spring is purpose-built for hygienic, high-purity environments such as food processing and pharmaceutical equipment. Manufactured from AISI 316L (SS316L) stainless steel, it delivers outstanding resistance to chlorides, acids and wash-down chemicals that would quickly corrode standard carbon steel springs.

Each spring undergoes a precision electro-polishing process that removes surface imperfections and creates a smooth, bright, passive oxide layer. This dramatically reduces the risk of product adhesion, bacterial retention and particle shedding, making the spring ideal for contamination-sensitive applications.

Available in wire diameters from 0.3mm to 12mm and free lengths from 5mm to 500mm, the spring can be supplied with closed and ground ends for stable, repeatable load performance. Strict in-house quality control ensures consistent spring rate and dimensional accuracy batch after batch.
