Abstract : The PH-13 13-8 Mo is a precipitation hardenable stainless steel. This steel can be heat treated to 225 ksi and has excellent toughness, general corrosion, and stress corrision at this strength level. The fatigue life is comparable to 4330 in both the smooth and notched conditions. Exposure to temperatures in the 800 to 900F range for extended times reduces the toughness of this steel and use in this temperature range is not recommended. (Author)
