● Zoo mechanical zog – tensile, qaug zog thiab creep-rupture
● Tawm lub zog tensile, creep, thiab rupture lub zog muaj zog heev
● Cov tshuaj tiv thaiv zoo heev rau chloride thiab sulfide kev nyuaj siab corrosion tawg
● Resistant rau aqueous corrosion thiab chloride ion kev nyuaj siab corrosion cracking
● Kub kub resistant
● Hnub nyoog-hardenable nrog cov khoom tshwj xeeb ntawm kev laus qeeb qeeb uas tso cai rau cua sov thiab txias thaum lub sij hawm annealing yam tsis muaj kev phom sij ntawm kev tawg.
● Zoo heev vuam yam ntxwv, resistant rau postweld hnub nyoog tawg
