Prodec® 316 / 316L

Prodec® 316/316L is an improved version of standard 316L for improved machinability and outstanding uniformity. Prodec® 316/316L offers faster machining speeds, longer tool life, improved part quality and lower total cost of machined parts. Prodec® 316/L provides improved resistance to pitting and crevice corrosion in environments containing chlorides and other halides.

Although improvements in machinability in the past have been associated with reduced corrosion resistance, Prodec® 316/316L has shown corrosion resistance within the range typically expected of 316L stainless steel. It is common for Prodec® 316/316L to be dual certified as Prodec® 316L and Prodec® 316 because the material meets both the lower carbon limit of 316L and the slightly higher strength of 316.

Prodec® 316/316L is readily welded by a full range of conventional welding procedures except oxyacetylene. AWS E316L/ER316L and other low carbon filler metals with molybdenum content higher than that of the base metal should be used with Prodec® 316/316L stainless steel.
