Answer
A $1000^{\circ}F$, Inconel X-750 shine mafi kyawun zaɓi don maɓuɓɓugan ruwan raƙuman ruwa saboda babban abun ciki na nickel (minti 70%) da samuwar barga mai kariya $Cr_2O_3$ Layer oxide. Yana kiyaye kaddarorin sa na bazara kuma yana tsayayya da hazo ta $\gamma'$ hazo. A286 (wani ƙarfe-base superalloy) shima dacewa har zuwa $1000^{\circ}F$ amma ya fi dacewa da iskar oxygen da asarar modules a saman ƙarshen wannan kewayon. Modular elasticity $E$ na Inconel X-750 yana sauke daga $31 imes 10^6$ psi a dakin zafin jiki zuwa kusan $25 imes 10^6$ psi a $1000^{\circ}F$, al'amari wanda dole ne a haɗa shi cikin lissafin ƙimar ($ k \ propto E $). Ana zaɓin A286 sau da yawa don ƙimar sa mai tsada lokacin da matsanancin juriya na Inconel ba a buƙata ba.
