Mai ʻae i nā nīnau
E hoʻomau mau iā ʻoe
Paʻa ʻole ʻo Arc
ʻO ka hoʻoheheʻe ʻana
ʻO ka pipiʻi nui
Hoʻohana maʻamau i nā mīkini meaʻai, nā mea lapaʻau, nā moku kaomi
Petrochemical a me nā manawa ʻē aʻe e like me 1Cr19Ni11Nb(SUS347).
Maikaʻi ka ripple
Ma muli o ka hoʻohui ʻana o Nb, maikaʻi ka metala i waiho ʻia
ʻO ke kūpaʻa corrosion intergranular a me nā waiwai mechanical paʻa
Paʻa arc, nani hana, maikai kahe o ka hao hehee, me ka maikai loa kuʻihao kaʻina hana
ʻO ka slagging maʻalahi
