Type 317 and its low carbon variation 317L are austenitic stainless steels. With higher Chromium, Molybdenum and Nickel content than 316, it has both increased corrosion performance and higher temperature applications. It has greater resistance to both pitting and crevice corrosion in most environments. Think of it as type 316 on steroids. The solution annealed condition aka Cond A offers the best corrosion performance. Typical solution anneal is from 1850 to 2050 deg F followed by rapid cooling to prevent carbide formation.
Is 317 Magnetic? 317 and 317L are considered non - magnetic in the annealed condition.
