I te ao hangarau hanganga, kāore te neke atu i te maitai waro paerewa i te mea papai - engari he mea nui mō te mahi me te pumau. Mā te maitai kaha teitei, te HSS rānei, ka taea te hanga hoahoa hiroki ake, te whakaiti i te rahinga whakarewa, me te whakaiti i ngā utu kawe.
Heoi, he maha ngā wā ka whakapoauautia te hunga e whakamahi ana i ngā tikanga whakaingoa o ngā paerewa Pākehā. Ehara i te mea he tapanga noa iho te whiriwhiri i waenga i te S460MLH me te S460NH; engari ka tohutohuhia te āhua o te whakarewa, te hanga, me te āhua o te mahi i roto i ngā pāmahana i raro i te kore.
—–Te Wetewete i te Aronga Taumata———————————
Ko te uara tau i roto i tētahi māka EN, pērā i355ko te 960 rānei, e tohu ana i te kaha hua iti rawa i inehia i roto i ngā megapascal. Ahakoa ko S355 tonu te hoiho mahi o te ao mō te hanganga whānui, kei te tere te neke o te umanga kiS460me S690 hei whakatutuki i ngā whāinga whakaiti taumaha.
Te Pānga o te Tukatuka: M, N, me Q
Ko te reta i muri i te kaha e tohu ana i te āhua tuku, koinei pea te mea tino nui mō te hanga.
- Raupapa-M (Hurihia mā te Wera):Ka tukatukahia ēnei maitai i ngā awhe pāmahana motuhake kia eke ki te kaha teitei me ngā waro iti rawa. Nā tēnei ka tino ngāwari te whakarewa i te maitai raupapa-M, ā, ka kore e hiahiatia te whakamahana i mua ahakoa i ngā wāhanga matotoru ake.
- Raupapa-N (Kua Whakaōritea):He tikanga tuku iho tēnei e whakamahanatia ai te maitai kia ōrite te hanganga o te kōhao. He tino pumau, ā, he pai ake mēnā ka whakamahanatia anō te maitai, ka hangaia rānei i te wā e hangaia ana.
- Raupapa-Q (Kua tineia, kua whakamahanatia):Koinei te paerewa koura mō te kaha tino teitei. Mā te whakamatao tere i te maitai, kātahi ka whakamahana anō, ka tutuki i a tātou te kaha whakaputa mai i te 690 MPa ki te 960 MPa. Heoi, me tino whakahaere te pāmahana o ēnei momo i te wā e whakarewahia ana kia kore ai e whakangawari te rauemi.
—–Te Hiranga o te Pakari i te Pāmahana Iti——————————
Ko te kaha te haurua noa iho o te kōrero. I te mea ka pakeke haere te maitai, ka ngawari ake te pakarukaru. Hei ārai i tēnei, me rapu e ngā kaihangarau ngā tohu L, L1 rānei.
Ko ngā taumata paerewa e kī taurangi ana i te kaha pānga i te -20°C. Mena he kino ake ngā taiao o tō kaupapa—pērā i ngā papaaho taimoana, ngā taputapu teitei, ngā hanganga ā-arctic rānei—me tohu e koe te MLH, te NLH rānei mō te mahi i te -40°C, te QL1H tino pai rānei mō te pono ki raro ki te -60°C.
Te Whakamahinga Rautaki o te Rino Kaha Teitei
| Taumata Kaha | Ngā Taumata Tuatahi | Te Whakamahinga Pai rawa atu |
| HSS Paerewa | S355NH, S355MLH | Ngā whare putunga, ngā anga māmā, me ngā hanganga pumau. |
| HSS Mahi | S460NH, S460MLH | Ngā poupou piriti, ngā pou teitei, me ngā uhi tai. |
| HSS Tino-Teitei | S690QL1H, S960QL | Ngā pūoro kerēne, ngā ringa karu tiro, me ngā taputapu keri maina. |
| HSS Āhua | S700MC | Te anga taraka me ngā wāhanga matatini kua takai-matao. |
—–Ngā Pātai Auau——————————
Q1: Ka taea e au te whakakapi tika i te S355 ki te S960 hei whakaiti i te taumaha?
A1: Kāore rawa. Ahakoa e tata ana ki te toru ngā wā te kaha o te S960, ka mau tonu te āhua o te maitai. Mena he "peke" te "pakari" rānei tō hoahoa, kaua ki te "kaha", tera pea ka wiri, ka piko rawa rānei te wāhanga angiangi o te S960. Me hanga anō e koe te āhuahanga kia tino whai hua ai te kaha teitei ake.
Q2: He aha te rerekētanga o S700MC i S690QH?
A2;Ahakoa he ōrite ō rāua kaha, he mea hanga motuhake a S700MC mō te hanga matao me te piko. He pereti hurihuri wera (MC) e taea ai te tu atu ki ngā porowhita piko kikī me te kore e pakaru, engari ko ngā maitai raupapa-Q (QH) he mea arotau mō ngā wāhanga hanganga tuwhera me ngā pereti taumaha kei reira te kaha kawenga tere te mea nui.
Q3: Ka pāngia te kaha o te S960 e te whakarewa?
A4: Āe. Ko ngā maitai tino kaha ka whakawhirinaki ki te maimoatanga wera tika. Mena he nui rawa te "whakauru wera" whakarewa, ka hangaia he Rohe Whakangawari i te rohe e tata ana ki te whakarewa. Ka whakaitihia te kaha ā-rohe o te hononga. Me whai ngā kaiwhakarewa i ngā tikanga tino pakari e pā ana ki ngā pāmahana i waenga i ngā ara me ngā tere whakamatao.
Q4: He māmā ake te whakarewa i te S460MLH i te S460NH?
A4: Ae, i te nuinga o te wā. Nā te mea e whakamahia ana e ngā momo MLH te hurihanga wera-mīhini, ka eke ki tōna kaha me te iti ake o ngā huānga whakarewa pēnei i te waro me te konupora. Nā te iti o te waro ōrite ka iti ake te pakaru o te maitai i te hauwai, ā, ka kore e hiahiatia te whakamahana i te konganuku i mua i te whakarewa.
P5: He aha te tohu o te "H" i te mutunga o ēnei māka?
A5: Ko te H e tohu ana i te Wāhanga Poka. Ahakoa he ngongo porowhita, he ngongo tapawhā, he ngongo tapawhā rānei te paipa, ka whakaū te tāpiritanga H kua tutuki i te rauemi ngā whakaritenga motuhake o ngā paerewa EN 10210, EN 10219 rānei mō ngā wāhanga poka hanganga.
