SUS316L Stainless Steel: Low Carbon for Welding Excellence

What is SUS316L?

It's a low-carbon version of 316 stainless steel, with the "L" signifying low carbon.

It contains molybdenum, enhancing resistance to pitting and crevice corrosion, especially in chloride environments.

When heated during welding, standard 316 can form chromium carbides at grain boundaries, depleting chromium and creating susceptible areas for corrosion (weld decay).

The low carbon in 316L minimizes carbide formation, maintaining corrosion resistance throughout the weld zone in its as-welded condition.

Better than 316 for heavy-gauge welded components.

Excellent resistance to intergranular corrosion after welding.

Offers good strength and toughness from cryogenic to elevated temperatures.
