Typus 321 (UNS S32100) in Coil Tubingae
Descriptio
Typus 321 est titanium chromium austeniticum inactum cum corrosione resistentiae simile 304/304L stabilitum.Hic gradus typice usus est in range 800-1500˚F temperaturae ubi stabilitur contra praecipitationem chromium carbidam, accessione titanii, quod consequitur in praecipitatione carbidum titanii.Typus 321 optimam habet resistentiam corrosionis intergranulares post exposita huic range temperaturae, et hic gradus resistit oxidationis usque ad 1500˚F, et altius serpit et accentus rupturae proprietates habet quam 304/304L.Etiam bonam habet frigiditatem temperaturae duritiem et non magneticam in annealed conditione.
