SAE4320 Thru Carburized (Vacuum)

SAE4320 Thru Carb.(Vacuum) Case Axial CA BHN=653 HRc=60 (AISI It 167 )
- Microstructure Report (Cryderman)
- Metallurgy Report for PhaseXII (Dana )(16Mb)
- Micro A Micro B
- Tensile tests and Cyclic Stress-Strain
  ( note that cyclic is above S_ultimate, probably due to the
  20.1% Retained Austenite. Unfortunately 1/2 life mean stess
  was not reported )
