Rīpene maitai kore waikura 309me te 310 he koranu maitai kore waikura austenitic ātete-wera, engari he rerekētanga kei roto i ō rāua hanganga me ngā whakamahinga e tika ana. 309: He pai te ātete ki te pāmahana teitei, ā, ka taea te tu atu i ngā pāmahana tae atu ki te 1000°C (1832°F). He maha ngā wā ka whakamahia i roto i ngā wāhanga oumu, i ngā whakawhiti wera, me ngā taiao pāmahana teitei. 310: He pai ake te ātete ki te pāmahana teitei, ā, ka taea te tu atu i ngā pāmahana tae atu ki te 1150°C (2102°F). He pai mō ngā whakamahinga i roto i ngā taiao wera nui, pērā i ngā oumu, ngā oumu, me ngā ngongo hihi.

Hei whakarāpopototanga, ko ngā rerekētanga matua i waenga i ngā rīpene maitai kore waikura 309 me te 310 kei roto i ō rātou hanganga me te ātete ki te pāmahana. He nui ake te chromium o te 310, he iti ake te ihirangi nickel, ā, he pai ake mō ngā tono pāmahana teitei ake i te 309. Ko tāu whiringa i waenga i ngā mea e rua ka whakawhirinaki ki ngā whakaritenga motuhake o tō tono, tae atu ki te pāmahana, te ātete ki te waikura, me ngā āhuatanga miihini.
