Incoloy 825 Hardness
Typical Hardness:
Brinell Hardness (HB): 160 – 220
Rockwell Hardness (HRB): 80 – 95 (depending on heat treatment and condition)
Influencing Factors
Heat Treatment: Annealing, solution treatment, or aging affect hardness levels.
Cold Working: Mechanical deformation (cold rolling, drawing) increases hardness due to strain hardening.
Chemical Composition: Variations in alloying elements like nickel, chromium, molybdenum influence hardness.
Microstructure: Grain size and phase distribution can impact hardness.
Impurities and Defects: Inclusions, porosity, or segregation can cause hardness variations.
Features
