Precipitaion Hardening RVS
Alloy mei hege temperatuer
◆0Cr17Ni7Al is in delslach-hardening stiel mei Al tafoege, brûkt as springs, washers, rekkenmasine komponinten, ensfh
◆0Cr15Ni7Mo2Al wurdt brûkt foar hege-sterkte konteners, dielen en strukturele dielen mei bepaalde corrosie ferset easken.
◆De prestaasjes fan 0Cr15Ni5Cu4Nb is fergelykber mei dy fan 0Cr17Ni4Cu4Nb, mar it hat bettere laterale prestaasjes.
◆0Cr12Mn5Ni4Mo3Al (Gangyan 69111) hat bettere plastykens as 0Cr15Ni7Mo2Al.
◆0Cr17Ni4Cu4Nb Precipitation ferhurding stiel mei Cu tafoege, in soad brûkt yn shafts, hege-sterkte strukturele dielen easkje corrosie ferset foar stoom turbine dielen.
◆XM-25 is waarmte- en hege temperatuerresistint, geskikt foar piteroalje, gemyske, loftfeart, kearnkrêft en oare yndustry.
