Answer
$ 17-7PH $ (AISI 631) mumiterere ya CH900 itanga urwego rwiza rwimbaraga nyinshi hamwe no kurwanya ruswa ugereranije na $ 302 $ Steelless Steel. $ 17-7PH $ ihura nigikorwa cyo gukomera kwimvura (Imiterere C kugeza CH900) itanga imbaraga zingana kugeza $ 240 $ ksi. Ibi bituma urwego rwinshi rwo guhangayika ($ σ_ {byose} \ hafi 0,75 \ cdot σ_ {uts} $) hamwe nintambwe ntoya kumutwaro umwe. Byongeye kandi, $ 17-7PH $ yerekana uburyo bwiza bwo kwihanganira ubushyuhe bugera ku $ 650 ^ {∘} F $ ($ 343 ^ {∘} C $). Ibinyuranye, $ 302 $ Amashanyarazi, nubwo ahendutse kandi ahindagurika cyane, agarukira hafi $ 550 ^ {∘} F $ ($ 288 ^ {∘} C $) kandi afite umunaniro muke. Kubutumwa bwingenzi bwibintu byo mu kirere, ihinduka ryicyiciro muri $ 17-7PH $ ritanga ihame ryimiterere isabwa kugirango kwihanganira imiraba yimvura.
