Better corrosion resistance than Type 304. Low carbon chromium-nickel stainless with good weldability and temperature resistance. Max. temp. to maintain corrosion resistance is 1600 degrees F.
This austenitic stainless steel has an increased molybdenum content to increase its resistance to corrosion when compared to other 300 series alloys.
316 is recommended for any application exposed to saltwater (including immersion).
