Rau siab -kub engineering, dab ntxwg nyoog yog nyob rau hauv cov ntsiab lus -tshwj xeeb tshaj yog ntxiv cov kab lus. Txawm hais tias ob qho tib si alloys siv npib tsib xee-chromium ua cov matrix, lawv qhov sib txawv tseem ceeb nyob hauv lawv cov txheej txheem hardening. Nimonic 75 (UNS No. 6075) tsuas yog siv titanium los kho cov nplej thiab txhim kho cov tshuaj ruaj khov. Nimonic 80A (UNS No. 7080), ntawm qhov tod tes, ntxiv qhov tseem ceeb ntawm txhuas thiab titanium, ua rau 'theem los ntawm nag lossis daus hardening. Raws li tus kws tshaj lij npib tsib xee alloy xa khoom, Gnee Steel muab cov ntaub ntawv{11}}tsav kev sib piv los xyuas kom meej qhov kev ncaj ncees ntawm cov khoom siv kho tshuab rau koj cov haujlwm.
