Koranu 32760 (Plate) (uns S32760)
Whakamārama:
Koranu 32760 Ko te kowiri tira super Matarua tukua i roto i te huru i mahi, me te otinga annealed wera. Ka rite ki te he kowiri tira super Matarua, fakatahai reira nga āhuatanga e minaminatia o e rua māka austenitic me ferritic. hua nga tirotiro chromium, molybdenum me te hauota teitei i roto i te tau ōrite Pitting Ātete (PREN) o> 40, whakarato pitting me te kapiti te waikura ātete pai ki steels tira austenitic me Matarua i roto i pāpāho tata ha'iriiri katoa, me te Temperature Pitting Critical rawa 50 ° C nb.versions o te tātai PREN ngā ano W rite te mana pai i runga i ātete pitting whānui.
E whakarato ana te kaha ki runga ake i rua austenitic me 22% Cr Matarua steels kowiri, a kua whakarārangitia i roto i NACE MR 0175 mō te mahi kawa, me te ASME mō tono pēhanga oko.
