DESCRIPTION
317L is a molybdenum bearing austenitic chromium nickel steel similar
to type 316 except the alloy content in 317L is somewhat higher. It
has superior corrosion resistance in special applications where it
is desired to reduce contamination to a minimum. 317L was developed
primarily to resist more effectively the attack of sulfurous acid
compounds. However, its proven ability to combat corrosion has widened
its use considerably and is now being used for many other industrial
applications. The low carbon content of 317L provides immunity to
intergranular corrosion in applications where heavy cross-sections
cannot be annealed after welding or where low temperature stress relieving
treatments are desired.
DESIGN
FEATURES
• A molybdenum bearing austenitic chromium nickel steel with an alloy
content somewhat higher than the 316 grades.
• Superior corrosion resistance in difficult
environments.
• Higher creep, stress-to-rupture and tensile
strengths than other stainless steels.
• Reduced intergranular precipitation of chromium carbides during
welding and stress relieving as well as minimized possibility of corrosion
failure from intergranular attack due to low carbon content.
• Resistance to pitting and crevice corrosion making 317L a successful
life-cost product in a variety of highly corrosive environments.
TYPICAL
APPLICATIONS
Flue gas desulfurization scrubber systems
Chemical and petro-chemical processing equipment
Pulp and paper plants
Food processing equipment
Textile equipment
TENSILE
REQUIREMENTS
Tensile Strength (KSI) 75
