Description      

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

Corrosion Resistance   

Refer to NACE (National Association of Corrosion Engineers) for recommendations. 

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. 
* Not all finishes are available in all alloys - Contact Ulbrich Sales for more information.

Wire Finishes  

XC - Extra clean bright annealed or bright annealed and cold rolled  Grease - Ultra-bright finish (for decorative applications)  Soap - Soap is not removed from tempered wire to act as a lubricant. 

* Contact Ulbrich Wire for custom wire finishes.

Cold Forming

Type 317 can be readily formed and drawn. 

Heat Treatment  

Type 317 is non hardenable by heat treatment. 

Welding 

For best results refer to: SSINA's "Welding of Stainless Steels and Other Joining Methods".
