I need some help finding the mechanical properties of "stainless steel hardening by precipitation 17-4PH, with H900 treatment", more specifically, I am having some trouble to find the Yield Stress, Young's Modulus and Fracture Toughness (Kic).
from my point of view, the bible for all these questions related to steels and treatments is always the "ASM Specialty Handbook Carbon and Alloy Steels". You may ask your Institution for availability. Many questions about physical and mechanical properties did find an answer for me in the past.
