Te whakarewa maitai kore waikuraHe tukanga tino nui tēnei i roto i te hanga hou, e hiahia ana ki ngā mea pau hei whakarite i te ātete ki te waikura me te hanganga pai. He taputapu taketake te hiko E308-16 i hangaia mō tēnei kaupapa. Hei hiko kua pania ki te momo titanium, kua hangaia hei whakamahi me ngā maitai kore waikura waro-iti rawa, e hanga ana i tētahi wāhanga matua o te maha o ngā tukanga tiaki me te hanga ahumahi. Ko te pono o te hanganga whakarewa katoa e whakawhirinaki ana ki te kōwhiringa tika o aua hiko motuhake, e mea nui ai te mārama ki ō rātou āhuatanga mō ngā kaiwhakarewa me ngā miihini.
He mea hanga matū te hikohiko E308-16 mō te whakamahinga tuatahi i roto i te whakarewa maitai kore waikura: te hono i te 18% chromium me te 8% nickel steels. Ko tēnei hanganga tētahi o ngā momo austenitic tino noa, ā, he mea taurite te matū putunga o te hikohiko kia ōrite ki tōna ātete ki te waikura me ngā āhuatanga miihini. Ko te tohu "L" i roto i tōna konganuku turanga e ōrite ana e tohu ana i te iti o te ihirangi waro, he mea nui hei ārai i te maturuturunga o te carbide i te wā o te tukanga whakarewa. Mā tēnei ka mau tonu te ātete o te hononga whakarewa ki te waikura intergranular, he wāhi pakaru noa i roto i te maitai kore waikura kāore i whakarewaina tika.
Ko te whānuitanga o te tono mō tēnei hikohiko i roto iwhakarewa maitai kore waikuraHe whānuitia, inā koa i roto i te rāngai ahumahi. He tino pai mō te hanga hanganga i hangaia mai i te maitai kore waikura 022Cr19Ni10 (he paerewa Hainamana noa e rite ana ki te 304L). He whānuitia te whakamahinga i roto i te hanga taputapu mō ngā taiao uaua, ngā tipu muka hangai, ngā whare hanga tongi me ngā taputapu hinu-matū. I roto i ēnei tono, he mea nui te kounga whakarewa e whakaratohia ana e te E308-16 hei pupuri i ngā mea waikura me te pupuri i te haumaru mahi.
Nā ngā āhuatanga mahi o te E308-16 he mea whai hua mō ngā tūranga whakarewa rerekē. Ko te kupu whakamutunga "-16" i roto i tōna whakarōpūtanga e tohu ana he paninga raima-titania tōna, e tautoko ana i te whakarewa i ngā tūranga katoa.—papatahi, whakapae, poutū, me te tuanui. He painga nui tēnei i roto i te hanga me te mahi whakatika i te papa, ina kore e taea te whakanoho anō i ngā wāhanga. He pumau te pewa, he ngāwari te tango i te para, ā, he maeneene te āhua o te pītiti, e whai wāhi tahi ana ki ngā mahi whakarewa maitai kore waikura kounga teitei, whai hua me te iti o te horoinga i muri i te whakarewatanga.
He mea hanga tika te hikohiko E308-16 hei paunga e aro ana ki ngā wero motuhake owhakarewa maitai kore waikurai runga i ngā taumata waro tino iti. Ko tōna whakamahinga matū kua tautuhia mō ngā maitai 18-8 me tōna pai mō ngā ahumahi nui pēnei i ngā matū hinu me ngā maniua e whakaatu ana i tōna hiranga. Mō ngā tohunga e mahi ana i te whakarewa maitai kore waikura, ko te whiriwhiri i te hiko E308-16 mō ngā kaupapa e tika ana ka whakarato i tētahi huarahi pono hei whakatutuki i ngā whakarewa pakari, ātete-waikura e tutuki ai ngā tono pakari o te mahi me te haumaru i roto i ngā tono ahumahi.
