316 Stainless Steel Spring Applications
The presence of molybdenum and a slightly higher nickel content make 316 Stainless Steel suitable for architectural applications in severe settings, from polluted marine environments to areas with sub-zero temperatures. It also has better corrosion resistance compared to 302 stainless steel, particularly to pitting, making 316 an excellent choice for corrosion-resistant marine springs.
316 stainless steel is one of the most optimal materials to use when exposed to chlorides. It also performs better in marine environments, particularly when exposed to air with high salt content. The corrosion resistance of our custom 316 stainless springs will also shine through when exposed to different acids such as sulfuric acid, phosphoric acid, and formic acids. Coiling Tech's 316 stainless steel springs are also highly temperature resistant, being able to withstand extremely low temperatures and extremely high temperatures.
316 Stainless Steel Springs are commonly used in the following industries:

316 Stainless Steel Springs FAQs
What makes 316 stainless steel a good choice for springs in corrosive environments?
316 stainless steel contains approximately 2–3% molybdenum in addition to chromium and a slightly higher nickel content than 302/304 stainless steel. The molybdenum addition meaningfully improves resistance to pitting corrosion—the localized attack mode that causes 302 and 304 stainless to develop rust spots when exposed to chloride-containing environments like marine atmospheres, de-icing salts, or industrial process fluids. This makes 316 stainless the preferred austenitic grade for springs in polluted marine environments, chloride-containing industrial processes, and general severe corrosion settings where 302 stainless is not adequate.
What is the maximum operating temperature for a 316 stainless steel spring?
316 stainless steel springs are suitable for continuous service up to approximately 700°F (371°C), giving them a wider high-temperature margin than 302 stainless (approximately 500°F) while maintaining good corrosion resistance. Above 700°F, precipitation-hardening stainless grades (17-7 PH) or nickel superalloys (Inconel 718) are the more appropriate specifications.
How does 316 stainless compare to 302 stainless for spring applications?
316 stainless offers meaningfully better pitting corrosion resistance due to its molybdenum content, making it the correct specification for marine, saltwater-exposed, or chemically aggressive service environments. 302 stainless is a more cost-effective option for less corrosive general-purpose applications and provides adequate performance in most indoor or dry outdoor environments. For any application with seawater exposure, chloride-containing process streams, or regular contact with chlorinated cleaning agents, 316 stainless is the superior material choice.
Can 316 stainless steel springs handle sub-zero or cryogenic temperatures?
Yes. 316 stainless steel—like all austenitic stainless steels—does not undergo the ductile-to-brittle transition that affects carbon and low-alloy steels at low temperatures. It maintains good ductility and toughness at sub-zero temperatures, which is one reason it is widely specified for architectural and marine applications exposed to cold climates and temperature extremes. For cryogenic applications at very low temperatures (liquid nitrogen, LOX), Inconel alloys or specific cryogenic stainless grades are more commonly specified.
What industries typically specify 316 stainless steel springs?
316 stainless steel springs are common in: marine and offshore equipment (deck hardware, rigging components, corrosion-resistant actuators), chemical and petrochemical processing (valve springs in chloride-containing or acidic process fluids), food and beverage processing (equipment springs in CIP (clean-in-place) and steam sterilization environments), pharmaceutical manufacturing (springs in sterile process equipment), architectural and design applications (springs in high-end marine-grade hardware), and medical equipment where non-implantable components require corrosion resistance in steam or disinfectant-exposed environments.
