ʻO ka pā kila kila SUS347 H

ʻO SUS347 (347/S34700/0Cr18Ni11Nb) kahi ʻano kila me ke kila kila austenitic me ke kūpaʻa maikaʻi i ka pala kristal.
Loaʻa iā ia ke kūpaʻa maikaʻi i ka ʻaika, alkali a me ka paʻakai wai, a he kūpaʻa maikaʻi i ka oxidation a me ka weldability i ka lewa ma lalo o 800 °C. Loaʻa i ke kila kila 347 ka hana maikaʻi loa o ka haki ʻana i ke koʻikoʻi wela kiʻekiʻe (Stress Rupture) a ʻoi aku ka maikaʻi o nā waiwai mechanical stress kū'ē i ke kiʻekiʻe wela ma mua o ke kila kila 304. Hoʻohana nui ʻia i ka mokulele, ka hana mana, ka kemika, ka petrochemical, ka meaʻai, ka pepa a me nā ʻoihana ʻē aʻe.
