Hyundai S-316.16N description: S-316.16N is a lime-titania type electrode provided with a good usability and weldability. As the all-weld metal has an austenite structure including Mo., the corrosion resistance against sulfide acid, phosphoric acid and acetic acid is excellent and heat resistance is also much better than that of 18%Cr-8%Ni stainless steel welds.
