ʻIkepili o ka Paipu Kila Kila 904L
ʻO ke kila kila kila 904L he chromium, nickel, molybdenum a me nā mea keleawe, hāʻawi kēia mau mea i ke ʻano kila kila kila 904L i nā waiwai maikaʻi loa e pale aku ai i ka pala i loko o ka waikawa sulfuric dilute ma muli o ka hoʻohui ʻana o ke keleawe, hoʻohana pinepine ʻia ʻo 904L i ke kaomi kiʻekiʻe a me ke kaiapuni pala kahi e hana maikaʻi ʻole ai ʻo 316L a me 317L. Loaʻa iā 904L ka haku mele nickel kiʻekiʻe me ka haʻahaʻa o ke kalapona, hoʻomaikaʻi ka hoʻohui ʻana o ke keleawe i kona kūpaʻa ʻana i ka pala, ʻo ka "L" ma 904L ke kū nei no ke kalapona haʻahaʻa, he kila kila Super Austenitic maʻamau ia, ʻo nā papa like he DIN 1.4539 a me UNS N08904, ʻoi aku ka maikaʻi o nā waiwai o 904L ma mua o nā kila kila austenitic ʻē aʻe.
