2. 304L kila kila. I mea e hoʻoponopono ai i ka pilikia o ka hoʻomohala ʻana o ka ultra-low carbon austenitic stainless steel ma muli o ka ua o Cr23C6 e hoʻopiʻi ana i ke ʻano koʻikoʻi intergranular corrosion o 304 stainless steel ma lalo o kekahi mau kūlana, ʻoi aku ka maikaʻi o kona kūlana intergranular corrosion resistance ma mua o ka 304 stainless. kila. Ma waho aʻe o ka ikaika haʻahaʻa haʻahaʻa, ua like nā waiwai ʻē aʻe me 321 stainless steel. Hoʻohana nui ʻia ia no nā lako pale corrosion a me nā ʻāpana ʻaʻole hiki ke hoʻokō ʻia i ka mālama ʻana i ka hopena ma hope o ka wili ʻana, a hiki ke hoʻohana ʻia e hana i nā kino mea kani.

3. 304H kila kuhiliʻole. ʻO ka lālā i loko o ka 304 stainless steel he hapa kalapona o 0.04% -0.10%, a ʻoi aku ka maikaʻi o kāna hana wela ma mua o ka 304 stainless steel.

4. 316 kila kila. ʻO ka hoʻohui ʻana i ka molybdenum ma ke kumu o ke kila 10Cr18Ni12 e hoʻoikaika maikaʻi ai ke kila i ka hōʻemi ʻana i ka medium a me ka pitting corrosion. I loko o ka wai kai a me nā ʻano media ʻē aʻe, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o 304 stainless steel, i hoʻohana nui ʻia no nā mea paʻa pitting.

5. 316L kila kila. ʻO ke kila kalapona haʻahaʻa haʻahaʻa he kūpaʻa maikaʻi i ka sensitized intergranular corrosion a he kūpono ia no ka hana ʻana i nā ʻāpana welded a me nā mea hana me nā ana ʻāpana mānoanoa, e like me nā mea corrosion-resistant i nā lako petrochemical.

6. 316H kila kuhiliʻole. ʻO ka lālā i loko o ka 316 stainless steel he hapa kalapona o 0.04% -0.10%, a ʻoi aku ka maikaʻi o kāna hana wela ma mua o ka 316 stainless steel.
