Siab tiv taus kev ntxhov siab corrosion tawg yog tias muaj ntawm 550 degree lossis siab dua. Kev kub ntxhov siab dua muab SCC tiv thaiv zoo dua. Qib 630 tiv taus sulphide stresscracking (SSC) yog tias muaj hnub nyoog heev; NACE MR0175 tso cai siv 630 tab sis tsuas yog nyob rau hauv ob lub hnub nyoog laus (saib rau MR0175 thiab ASTMA564M).

Siab zog bolting thiab fasteners nyob rau hauv aerospace thiab tshuaj nroj tsuag daim ntaub ntawv. Cov alloy tau siv rau hauv kev lag luam petrochemical, roj av, ntawv thiab zaub mov thiab ua tau zoo. Cov hlau tseem siv tau rau lub nkoj kiv cua shafts, qhov twg nws yog muab raws li precision straightened, centreless av shafting. Nws kuj muaj xws li peev castings rau kev siv xws li nkoj fittings.
