17-7PH (ASTM A564) nicyuma cya austenitike yimvura-ikomera ibyuma bitagira umuyonga bitanga ibikoresho byubukanishi binyuze muburyo bwo kugabanya ubukonje (Imiterere C) no gukomera kwimyaka (CH900). Bitandukanye na 302 cyangwa 304 idafite umwanda, yishingikiriza gusa ku mbeho ikorera imbaraga kandi igatakaza ubushyuhe ku bushyuhe buri hejuru ya 250 C, 17-7PH CH900 ikomeza modulus yayo kandi itanga imbaraga kugeza kuri 343 C (650 F). Ubushyuhe bwa CH900 burimo gushyushya 482 C (900 F) kumasaha imwe, bigabanya imvange ikungahaye kuri aluminiyumu muri matrise ya martensitike. Ibi bivamo umunaniro mwinshi no kurwanya kuruhuka, bigatuma biba byiza kumasoko yumuraba mumashanyarazi ya moteri yo mu kirere aho ubushyuhe bwumuriro aribwo bwambere.
