Hoʻohana ʻia nā noi maʻamau ʻo Grade 310/310S i nā mea hoʻoheheʻe moe fluidised, kilns, radiant tubes, tube hangers for petroleum refining and steam boilers, coal gasifier internal parts, lead pot, thermowells, refractory anchor bolts, burners and combustion chambers, retorts, muffles, nā uhi annealing, saggers, nā lako hana meaʻai, nā hale cryogenic.

Loaʻa i kēia mau māka he 25% chromium a me 20% nickel, e hoʻokūpaʻa loa iā lākou i ka oxidation a me ka corrosion.ʻO ka papa 310S kahi ʻano kalapona haʻahaʻa haʻahaʻa, ʻoi aku ka liʻiliʻi i ka embrittlement a me ka sensitization i ka lawelawe.ʻO ke kiʻekiʻe o ka chromium a me ka nickel maʻamau e hiki ai i kēia mau kila no ka hoʻohana ʻana i ka hōʻemi ʻana i nā lewa sulfur i loaʻa iā H2S.Hoʻohana nui ʻia lākou i nā ea ea carburising, e like me ka mea i ʻike ʻia i nā wahi petrochemical.No nā lewa carburising ʻoi aku ka paʻakikī, pono e koho ʻia nā ʻāpana ʻē aʻe pale wela.ʻAʻole ʻōlelo ʻia ka papa 310 no ka hoʻopau pinepine ʻana i ka wai no ka mea ua pilikia ia i ka haʻalulu wela.Hoʻohana pinepine ʻia ka papa i nā noi cryogenic, ma muli o kona paʻakikī a me ka haʻahaʻa magnetic permeability.
E like me nā mea kila ʻole austenitic ʻē aʻe, ʻaʻole hiki ke paʻakikī kēia mau māka e ka mālama wela.Hiki ke hoʻopaʻakikī ʻia lākou e ka hana anu, akā ʻaʻole hiki ke hana ʻia kēia.
