A.2 Properties of metals in ASTM test program
The mechanical properties of the metals used in the ASTM Interlaboratory
test program10 are summarized in Table A-2. For all
metals, with the exception of Stellite 6B, specimens manufactured from
sheet and rod have been used in the erosion tests. For stainless steel
AISI 316 hardness values ranging from 153 to 205 HV (Hardness Vickers)
have been used. The measured incubation periods of AISI 316 have been
corrected with a special procedure9 to a hardness of
170 HV.
Austenitic stainless steel AISI 316 contains (in wt%)
17Cr-10Ni-2Mo-0.02-0.04C with a thermodynamically stable austenite
structure19. Stellite 6B® is a Co-alloy containing (in
wt%) 28Cr, 4.5W, and 1.1C, and normally supplied as mill-annealed
sheet20. Aluminium 6061-T6 is an Al-Mg-Si alloy which
has been heat treated for precipitation hardening. Aluminium 1100-O is
an unalloyed annealed soft aluminium21.
