Nga whakaipoipohe hiranga nui i roto i to tatou oranga o ia ra, a he maha ano nga waahanga me nga momo. Ko etahi o ratoue kiia ana ko nga tiwha mate. Ko temate patupatus me whakamahi i roto i tete tukanga whakaipoipo, no reira ka pa ki te oranga o te mate?

E ai ki te tohu alloying o mate maitai, te tikanganga tira wera werai roto i Haina ko 5CrNiMo me 5CrMnM.Such noa kōeke o pokepokea maitai me te 4Cr5W2VSi, 4Cr5MoVlSi, 4Cr5MoVSi, 3Cr2W8V me te 3Cr3Mo3VNb hanga-whaiaro, 3Cr2MoVNi (B2), 3Cr2MoVNi (B2), 3Cr2MoVNi (B2), 3Cr2MoVNi (B2), 3Cr2MoVNi (B2), 3Cr2MoVNi (B2), 3Cr2MoVNi (B2), 3Cr2W8V me te 3Cr3Mo3VNb i hanga-whaiaro i Haina (HM1), 25Cr3Mo3VNb (HM3), 4Cr3Mo3W4VTiNb (GR), 5Cr4W5Mo2V (RM2), 50Cr4Mo3SiMnVAl (012A1), 6Cr4Mo3Si2WV(CG20), SRM-1, etc.

Ko nga tira mate me te tohu whakarewa teitei ake; Ko nga tira mate makariri noa ko te CrWMn, Crl2, Crl2MoV, me etahi atu, 7CrSiMnMoV(CH), 65Cr4W3Mo2VNb(65Nb), SLM-LL, 6W8Cr4VTi(LMl), me te waro-parapara cimented. i whakawhanakehia e Haina.

He iti noa te utu o mua, engari he kino te whakamahi matawhānui, he poto te ora; He pai ake te mahi o muri, he roa ake te ora, engari he nui ake te utu.te hanga wahi, mate patupatuhangarau me te hanga i nga tikanga taputapu. I te nuinga o te waa, whiriwhiria he utu paku teitei ake engari he pai ake te utu o nga rauemi pokepokea ai.
