PRODEC® 316/316L

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® 316L 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.
