1-866-725-860917-4 PH Stainless Strip is the most widely used of all precipitation hardening stainless steels. It's a martensitic steel that combines high strength, corrosion resistance, impecable mechanical properties up to 600°F and good toughness.
Type 17-4PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties at temperatures up to 600 °F (316 °C), good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling.

The corrosion resistance of Type 17-4PH is comparable to that of Type 304 Stainless Steel in most media and superior to that of the hardenable 400 series stainless steels. Refer to NACE (National Association of Corrosion Engineers) for recommendations .
# 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 for all alloys - Contact Ulbrich Sales for more information.
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.
Type 17-4PH can be heat treated to increase mechanical properties. Contact Ulbrich Technical Service for information.
