5 15-5PH (H1025) Stainless Steel Alloy Material Description This 15-5PH Stainless Steel Alloy, heat-treated to the H1025 condition was provided by G. 0. Carlson, Thorndale, Pennsylvania. The plates were received in thickness,.s from to inches, widtbs varying from 10 to 16 inches, and lengths varying from 35 to 78 inches. The average chemical composition of this lot is as-- follows: Chemical Composition Percent Weight Carbon Manganese 0.32 Phosphorus Sulfur " Silicon 0.43 Chromium Nickel 4.73 Copper 3.27 Columbium 0.23 Tantalum 0.01 Iron Balance Processing and Heat Treating --- The 15-5PH stainless steel alloy was obtained as hotrolled plate that was solution annealed and pickled. Each plate was heat-treated separately to the H1025 condition. Results f The average values for eachaproperty are listed _D Table, -SLC by -a e diredtfhn. Due to the large numbers of data points (50 each from multiple heats for notched and unnotched specimens), o-ly fatigue bands are presented in Figures 1 and 2. The long transverse fatigue data were generated from one heat only and are presented as curves in Figures 3 and 4. 1 i f, ' -',',,',', " " ".'.' 4"..'". A 2..,,...'...
