NOTES:
A – H=Hydrogen Atmosphere L=Low Carbon H2=High Temperature N=Nitrogen Atmosphere N2=High Temperature DA Atmosphere
B – Density will vary depending on part configuration
C – Mechanical property values represent average values derived from test bars produced with production parameters
D – Elongation given as inch/inch in one inch gauge length
E – Relative scale with A+ passing ASTM B117 and ASTM B895 testing, C and lower having varying percentages of red rust depending on the components, exposure and application.
