Ka taea te wehe te upoko rakau ki te maka momo e rua nga waahanga ka patu i te momo wha-waahanga.
Ko tenei tuhinga hei toha atu ki a koe te mahinga mo te mahi e wha nga waahanga.
Ko te tuatahi, whakauruhia nga rauemi whakarewa ka whakamahia e to maatau upoko korowha.
1. Iti kiato me te kaha motuhake motuhake
2. Te kaha o te aukati i te waikura
3. Te kaha o te aukati i te wera
4. Te kaha o te awangawanga awangawanga iti
5. Te kaha o te kaha kaha me te whakaputa kaha
| Tau rauemi | Whakauru | Āhuahira |
| GR2 | Fe0.2, C0.08, N0.03, O0.25, H0.015 | Te kaha nui me te pai o te kirihouMaria rawa ki te hanga paipa. |
| GR3 | Fe0.2, C0.08, N0.03, O0.35, H0.015 | Te kaha teitei ake i te GR2, te iti o te kirihou I tino whakamahia mo te putorino hononga putorino. |
| GR4 | Fe0.2, C0.08, N0.03, O0.35, H0.015 | Ko te tino pakeke i waenga i nga titanium parakore o te umanga, hei whakamahi i te raro me te karauna |
| TC4 / GR5 | AL6 ， V4 ， Fe0.3, Si0.15, C0.1, N0.05, O0.2, H0.01 | Te kaha nui, e whakamahia ana mo te kanohi |
| TI2041 | AL4 ， V20 ， Sn1 | Whakanuia te pakeke e te maimoatanga wera, te tino kaha me te pai o te hiko |
1. Martensitic he kowiri tira (Aukume!)
He kowiri tira ko o raatau miihini ka taea te whakarereke ma te maimoatanga wera.
Ko tenei te akomanga o te maitai kowiri tira.
He teitei ake te pakeke i muri o te tinei, a he rereke te mahana o te mahana he rereketanga te kaha me te pakari.
Rauemi matua: SUS430, SUS431, SUS630 / S.S17-4, etc.
2. Austenite he kowiri tira (Korekore!)
He hanganga pumau kei raro i te paemahana noa, a kaore e taea te whakarereke i te pakeke ma te maimoatanga wera. He pakari nui me te kirihou, engari he iti te kaha, ka kaha noa ake ma te mahi makariri.
Rauemi matua: SUS202, SUS303, SUS304, SUS316 me etahi atu
3. Te taatai i te maitai rino (Aukume!)
Ko te koroheketanga e pa ana ki te mahinga maimoatanga wera e mau tonu ana te ahua, te rahi, te mahinga me nga whakarereketanga me te wa i muri o te tinei i te mahana nui, i muri ranei i te waahanga o te rereketanga o te mahi makariri ka whakanohoia ki te teitei o te wera o te ruuma o te ruuma ranei.
Rauemi Matua: SUS450, SUS455, SUS460, etc.

Rauemi Rauemi
Ka tapahia e te miihini whakahaere enei papa maitai, te pereti titanium ranei, kia roa te whiu, ka mutu tapahia enei whiu roa ki etahi o nga pereti rino o te rahi e tika ana.
Weld piu nga rauemi katoa e hiahiatia ana, katahi ka paiherea, a titoa 4-waahanga wahie Kua mahi upoko pakari.
