317L, is a kind of austenitic stainless steel.Mainly used for butterfly valve shaft, butterfly valve sleeve, etc.317L(00Cr19Ni13Mo3, UNS S31726) alloy is an austenitic stainless steel based on molybdenum.Compared with conventional chrome-nickel austenitic stainless steel such as 304 alloy, it has better chemical corrosion resistance.In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance.It is low carbon grade or L grade, which is resistant to sensitization during welding and heat treatment.
Compared with 316L, 317L steel has better seawater resistance and SCC resistance. It is used for Chemical equipment requiring high corrosion resistance such as Chemical ship, Chemical Product Reactor and so on.
Type 317 is an austenitic chromium-nickel stainless steel with excellent corrosion resistance; Its high Molybdenum content enhances the grade's superior pitting resistance. It is the most corrosion resistant of the 300 Series alloys and possesses the highest tensile and creep strength properties at elevated temperatures.

ADDITIONAL PROPERTIES
FINISHES
# 1 - Hot rolled annealed and descaled. It is available in strip,
foil and ribbon. It is used for applications where a smooth
decorative finish is not required.
# 2D - Dull finish produced by cold rolling, annealing and
descaling. Used for deep drawn parts and those parts that need to
retain lubricants in the forming process. # 2B - Smooth finish
produced by cold rolling, annealing and descaling. A light cold
rolling pass is added after anneal with polished rolls giving it a
brighter finish than 2D.
#BA- Bright annealed cold rolled and bright annealed
#CBA- Course bright annealed cold rolled matte finish and bright
anneal
#2 - Cold Rolled # 2BA- Smooth finish produced by cold rolling and
bright annealing. A light pass using highly polished rolls produces
a glossy finish. A 2BA finish may be used for lightly formed
applications where a glossy finish is desired in the formed part.
Polished - Various grit finish for specific polish finished
requirements.
COLD FORMING
Type 317 can be readily formed and drawn.
HEAT TREATMENT
Type 317 is non hardenable by heat treatment.
