Cov tshuaj muaj pes tsawg leeg ntawm high-chromium alloy hnav-resistant hauv ob sab phlu phaj mas suav nrog carbon, chromium, manganese, silicon, molybdenum, tungsten thiab lwm yam khoom. Ntawm lawv, cov ntsiab lus carbon yog qhov siab, uas tuaj yeem ncav cuag ntau dua 3.0%, uas ua rau cov khoom muaj hardness siab thiab hnav tsis kam. Cov ntsiab lus chromium feem ntau yog nyob ib ncig ntawm 26%, ntxiv dag zog rau kev hnav thiab corrosion kuj ntawm cov ntaub ntawv. Tsis tas li ntawd, qhov tsim nyog ntawm manganese, silicon, molybdenum, tungsten thiab lwm yam khoom los txhim kho lub zog, toughness thiab kub tsis kam ntawm cov khoom.
Hom kev hnav tsis kam hauv ob sab phlu no kuj muaj kev tiv thaiv zoo heev thiab kev tiv thaiv corrosion, nws hnav tsis kam tshaj li siab manganese steel hauv ob sab phlu lub neej nce ntau dua 2 zaug, kev ua haujlwm siab. Qhov saum npoo ntawm txheej hnav-tiv taus yog tiaj tus, tso tawm qhov kev ntxhov siab los ntawm kev tsim cov kab nrib pleb me me thiab zoo ib yam, tswj cov qib ntawm tag nrho cov phaj saum npoo, txwv tsis pub muaj kev ntxhov siab, qhov tawg tsuas yog txwv rau cov txheej nyuaj, thiab yuav tsis nthuav mus rau cov tawv steel phaj hauv kev siv cov txheej txheem ntawm toughness. Cov txheej hnav-resistant yog pom zoo kom siv nyob rau hauv 600 degree ua hauj lwm tej yam kev mob. Yog hais tias vanadium, molybdenum thiab lwm yam alloys ntxiv rau cov hlau txheej, nws tuaj yeem tiv taus qhov kub siab ntawm 800 degree.
