He kila kila 317

ʻO ka 317 stainless steel, i ʻike ʻia ʻo UNS S31700 a me Grade 317, ʻo ia ka mea nui o 18% a 20% chromium a me 11% a 15% nickel me ka nui o ke kalapona, phosphorus, sulfur, silicon a kaulike me ka hao.UNS S31700 /S31703 i ʻike nui ʻia ʻo Stainless Steel 317/317L Dual Certified ʻo ia ka mana haʻahaʻa carbon content o Stainless Steel 317 no nā hale welded.

ʻO nā hiʻohiʻona a me nā mea maikaʻi o ka Stainless Steel 317 a me 317 /317L Dual Certified me ka hoʻonui ʻana i ka ikaika, ka pale ʻana i ka corrosion (me ka crevice a me ka lua), ka ikaika tensile kiʻekiʻe a me ka ratio kiʻekiʻe o ke kaumaha-i-rupture. Kūʻē nā papa ʻelua i ka lua ʻana i ka acetic a me ka phosphoric acid. E pili ana i ka hana anu o Stainless Steel 317 a me 317/317L Dual Certified, hiki ke hoʻokō maikaʻi ʻia ka hoʻopaʻa ʻana, ka ʻako ʻana, ke kaha kiʻi a me ke poʻo. Eia hou, hiki ke hana ʻia ka annealing ma nā papa ʻelua ma waena o 1850 F a me 2050 F, a ukali ʻia e ka hoʻomaha wikiwiki. Eia kekahi, hiki i nā ʻano hana wela maʻamau āpau me Stainless Steel 317 a me 317/317L Dual Certified, ma waena o 2100 F a me 2300 F.
