ʻO Alloy 660 kahi kila kila austenitic paʻakikī i ʻike ʻia no kona ikaika kupaianaha i nā wela kiʻekiʻe a hiki i 700 ° C. Ua kūʻai ʻia hoʻi ma lalo o nā inoa, UNS S66286, a me A-286 alloy, Alloy 660 loaʻa kona ikaika mai kahi kiʻekiʻe o ke kūlike. Loaʻa iā ia ka ikaika hua haʻahaʻa haʻahaʻa o 105,000 psi a hoʻohana mau ʻia i nā mea hoʻopaʻa kiʻekiʻe a me nā mea bolting. ʻO nā noi ʻē aʻe no Alloy 660 ka:
- Nā ʻenekini mokulele
- Nā huila kinoea
- ʻO nā ʻāpana hoʻoili Turbo
I mea e noʻonoʻo ʻia ai he lālā o ka ʻohana Alloy 660, pono e komo i loko o ka hui kemika o ka alloy:
- Ni 24-27.0%
- Cr 13.50-16.0%
- Ti 1.90-2.35%
- Mn 2.0% ka nui
- Mo 1-1.5%
- ʻO 1.0% ka nui
- V 0.10-0.50%
- Al 0.35% ka nui
