Stainless steel 316L (UNS S31603) is a low carbon version of 316 stainless steel (“L” stands for Low Carbon) with a carbon content of ≤0.03%. It significantly reduces the risk of carbide precipitation (sensitization) during welding or high temperature environments, thereby avoiding intergranular corrosion and is suitable for more severe corrosive environments and welding processes.

Typical application scenarios
(1) Chemical and marine engineering
Chemical equipment: reactors, heat exchangers, acid storage tanks (resistant to sulfuric acid, hydrochloric acid, etc.).
Seawater treatment: desalination pipelines, marine pumps and valves, coastal power station condensers.
(2) Medical and food industries
Medical devices: scalpels, artificial joints, vascular stents (316L complies with ISO 5832-1/ASTM F138 standards).
Food processing: fermentation tanks, dairy pipelines (easy to clean, no metal pollution).
(3) Energy and environmental protection
Nuclear power plants: fuel assembly support structures (resistant to radiation and high-temperature water corrosion).
Flue gas desulfurization (FGD): absorption tower lining (resistant to SO₂/Cl⁻ corrosion).
(4) Construction and high-end manufacturing
Coastal buildings: bridge cables, curtain wall fasteners (resistant to salt spray).
3D printing: powder metallurgy 316L is used for complex aerospace components.
