316 Stainless Compression Springs
Our factory produces standard 316 stainless compression springs with wire diameters ranging from 0.3mm to 5.0mm and outer diameters from 5mm to 80mm. Free height can be customized from 10mm to 300mm according to precise load parameters. Every finished 316 stainless compression springs undergoes strict raw material inspection to guarantee stable chemical composition and mechanical properties.
Performance Advantages
Strong acid & alkali resistance
Molybdenum additive inside SUS316 material delivers powerful protection against sulfuric acid, hydrochloric acid, phosphoric acid and alkaline solutions.
Outstanding salt spray resistance
Outperforms SUS304 against pitting and crevice corrosion in coastal, marine and salt-laden environments.
Stable high-temperature performance
Retains reliable elasticity and strength under elevated temperatures with a wider working temperature range.
Optional low-carbon grade
316L version with carbon content ≤0.03% greatly improves intergranular corrosion resistance, suitable for welding and long-term high-temperature usage.
Application Fields
Mainly used for marine equipment, chemical machinery, medical devices, food processing lines, water treatment systems and ship fittings with severe corrosive surroundings.
Material Assurance
Baoding Zhongxin Spring Manufacturing Co., Ltd. owns a monthly steel wire output of 6,000 tons, with self-produced carbon steel wire to control raw material quality from the source. All stainless steel wire is sourced from qualified large steel mills with full incoming chemical and mechanical testing. Material certification documents can be provided upon request. As a direct manufacturer, we cut intermediate costs for carbon steel wire, while maintaining stable long-term cooperation with major stainless steel suppliers to ensure consistent supply and uniform quality.
