He mea maʻalahi ka poʻe e huikau i ka paipu kila kila 316 a me ka paipu kila kila 316L, me ka manaʻo he ʻano like ia o ka paipu kila, akā ʻaʻole maoli.
ʻO nā ʻokoʻa kikoʻī ma waena o 316 a me 316L stainless steels penei:
1. Hoʻohui kemika
ʻOi aku ka haʻahaʻa o ka ʻike kalapona o 316L stainless steel ma mua o ka 316 stainless steel.Hiki ke ʻōlelo ʻia ʻo "316L" he kila kila 316 ultra-low carbon.ʻO 316L kila kila he kiʻekiʻe ka molybdenum ma mua o 316.
2. Ke kū'ē i ka corrosion
ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion 316L.
3. Ka ikaika
ʻOi aku ka ikaika o nā waiwai mechanical 316.ʻOi aku ka kiʻekiʻe o ka ikaika tensile o 316 stainless steel paipu ma mua o ka 316L stainless steel paipu.Pono ka ikaika tensile o 316 stainless steel e ʻoi aku ka nui ma mua o 520MPa, ʻoiai ʻo ka 316L stainless steel e koi ʻia e ʻoi aku ka nui ma mua o 480MPa.ʻO kēia no ka mea ʻo carbon (C) kahi mea hoʻokumu austenitic ikaika, hiki ke hoʻomaikaʻi nui i ka ikaika o ke kila.
4. Kūleʻa wela kiʻekiʻe
Hiki ke hoʻohana mau ʻia ke kila kila 316L i ka wela kiʻekiʻe, ʻoiai ʻaʻole hiki iā 316.Ma ka laulā o 800 ~ 1575 degere, ʻoi aku ka maikaʻi ʻaʻole e hana mau i ka 316 stainless steel.ʻOi aku ka maikaʻi o ka carbide precipitation resistance o 316L stainless steel ma mua o ka 316 stainless steel, a hiki ke hoʻohana mau ʻia i ka laulā o 800 ~ 1575 degere.
5. wiliwili
ʻO 316 ke kila kila maikaʻi ka weldability, hiki ke hoʻopili ʻia e nā ʻano kuʻi maʻamau maʻamau.Pono ka pauku wiliwili o 316 kila kila ma hope o ka wiliwili ʻana i mea e hoʻomaikaʻi ai i kona pale ʻana i ka corrosion.Eia nō naʻe, inā hoʻohana ʻia ka 316L stainless steel, ʻaʻole koi ʻia ka post weld annealing.
