Type
316 Stainless Steel Carriage Screws-
-
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).
