Hei kaiwhakarato ahumahi matua, ka tukuna e mātou te tiwhiketeIrahiko Whakarewa E2594(AWS A5.4 E2594-16), he tohu arumoni AF2594-16. Kei roto i tēnei hiko kowiri tira kore-waikura takirua, he paninga konupūmā-tītaina, he iti rawa te waro, he ihirangi hauota rautaki hei whakarato i te ātete waikura tino pai. Ka puta i tana matū motuhake te konganuku whakarewa me te ātete pai ki te pakaru, te pakaru waikura ahotea (SCC), me te pakaru wera.–he mea tino nui mō ngā taiao whai rawa i te pūhaumāota pērā i ngā whare tukatuka matū me ngā hanganga moana ina kore e pai te mahi a ngā maitai kore waikura paerewa.
Te hikohiko'Ko te whai huatanga o tēnei mea i ahu mai i tōna hanganga waro iti e whakahaeretia ana (te nuinga o te wā <0.03% C) me te whakarei ake i te hauota me te molybdenum. Mā tēnei ka tutuki he whānuitanga Pitting Resistance Equivalent (PRE) o te 2-40 me te pupuri tonu i te hanganga moroiti austenite-ferrite taurite. Ka ārai te hoahoa whakarewa i te waikura intergranular me te pupuri i te pakari pānga puta noa i ngā pāmahana ratonga mai i ngā āhuatanga cryogenic ki te 300°C (572°F), e eke tonu ana ki runga ake i ngā whakaritenga ā-mīhini a te AWS A5.4.
I roto i te whakahaere, ko tēneiIrahiko Whakarewa E2594Kei roto ko te paninga titanium-konupūmā kua arotauhia hei whakarite i te pumau o te pewa DC+ me te tango i te paru i ngā tūranga katoa, tae atu ki ngā tono poutū ki raro. Ka whakaitihia e te paninga te mimiti hauwai (<5ml/100g), ka whakakorea ngā mōrearea pakaru makariri i roto i ngā hononga ātete-teitei. E ai ki ngā kaiwhakarewa whakarewa, he maeneene te whakawhiti whakarewa me te iti o te tauhiuhi me te ngāwari o te patu anō, ka whakarei ake i te hua i roto i ngā tono nui pēnei i te hanga oko pēhanga me te whakarewa paipa.
Ko te whakamana mahi e whakaū ana i te matū o te konganuku whakarewa he toharite 25.5% Cr, 9.5% Ni, 3.8% Mo, me te 0.22% N. Ko te whakamātautau motuhake a te ASTM G48 Tikanga A e whakaatu ana i te ātete ki te waikura o te poka e nui ake ana i ngā tohu takirua tikanga mā te 40°C (104°F). Ko te pauna wāhanga ferrite-austenite 45/55 e whakahaeretia ana ka tukuna he kaha hua o te 650-750 MPa (94-109 ksi) me te 25%+ te roa.–te tutuki i ngā whakaritenga ASME, EN, me NORSOK mō ngā hanganga matua.
Mō ngā tono waikura uaua, ko teIrahiko Whakarewa E2594Koia tonu te paearu mō te umanga. Ko tana mahi kua whakamātauhia i roto i ngā pūnaha tango tote, ngā papaaho moana, me ngā tauhohenga matū e whakarite ana i te pono. Ka tukuna i roto i ngā kete hiri korehau 4kg me te roa o te oranga 36-marama, kei roto i ngā rauemi katoa ngā tiwhikete motuhake mō te puranga. Whakapā mai ki tā mātou tīma hangarau mō ngā whakaritenga tukanga whakarewa motuhake mō te tono.
