Tsananguro pfupi:

Machubhu eSimbi Isina Kugayiwa eUNS S31254. UNS S31254 isimbi isina kugayiwa inogayiwa ine molybdenum nenitrogen yakawanda, ichidzivirira ngura nekuora kwenzvimbo dzakaita se316L. UNS S31254 isimbi isina kugayiwa inogayiwa umo kuwedzerwa kwechromium, molybdenum nenitrogen kunopa kudzivirira ngura mumvura yegungwa. Iyi alloy ine avhareji yeKuramba Kugayiwa kwenzvimbo dzakaita se43.8. Miedzo inoratidza kudzivirira ngura nekukasira mumvura yegungwa uye kusimbisa ngura mu sodium chloride inopisa. Kana ichienzaniswa neCrNiMo 17 12 2.5 steels, inoratidza kudzivirira ngura kwakanyanya mumaacid akawanda ane huwandu hwakafanana uye simba rayo rekugadzira rinokwira ne50%. Kugona kusundira zvakanaka uchishandisa Ni-Cr-Mo consumables. Kudzima simbi uye nguva pfupi mukati me600-1000°C zvinodzivirira kukura kwechikamu che sigma chinokuvadza, icho chinogona kukanganisa kuramba kwengura.
