Paipu kila austenitic super ASME SA213 · S31254.SMO254

Wehewehe Pōkole:

ʻO 254 SMO (UNS S31254) he kila kila austenitic e kūlike me nā kila kila austenitic ʻē aʻe a ua hoʻolālā ʻia me nā pae kiʻekiʻe o ka chromium, molybdenum, a me ka nitrogen no ka pale ʻana i ka pitting a me ka crevice corrosion. ʻO kēia mea hoʻohuihui he chromium-molydenum-nickel alloy me ka nitrogen mau ma ke ʻano he mea i hoʻohui ʻia; ʻo ka haku mele kokoke: Cr 20%–22%, Mo 6%–7%, Ni 18%–20%, a me ka nitrogen e hoʻonui ana i kona ikaika a me ke kūpaʻa i ka corrosion, ʻoi aku hoʻi i nā wahi e lawe ana i ka chloride e like me ke kai, e hana ana i ka pepa, pulp, a me nā ʻoihana kemika.
