– This is key to the strong corrosion resistance of 316L
Carbon content ≤0.03%, low carbon content reduces intergranular corrosion
316L is a low-carbon austenitic stainless steel. The "L" stands for Low Carbon. It is an improved version of 316 and is the most mainstream and reliable special-purpose stainless steel for liquid cooling, chemical, and seawater environments. It conforms to the standards ASTM A403, GB/T 12459, and GB/T 14976. It is commonly used for welded pipe fittings, pipes, elbows, tees, reducers, flanges, etc.
Extremely strong corrosion resistance: resistant to chloride ions, pitting corrosion, and crevice corrosion, far superior to 304 stainless steel.
Excellent weldability: low-carbon design, less prone to embrittlement and corrosion after welding, suitable for various welded pipe fittings.
Wide temperature range: commonly used -50℃～200℃, shorter-term resistance to higher temperatures.
Suitable for liquid cooling systems: resistant to water, ethylene glycol, deionized water, weak acids and alkalis, and municipal water/seawater.
Moderate strength, good toughness, vibration and impact resistance, suitable for computer rooms, data centers, and energy storage liquid cooling main pipelines.
Compared to 304 stainless steel: significantly stronger corrosion resistance, suitable for coastal, high-salt, and coolant environments.
Compared to 2205 duplex stainless steel: better toughness, easier to weld, and lower price.
Compared to Hastelloy: lower cost, meeting most common liquid cooling and chemical operating conditions.
