Nga taonga miihini
(5) Waahanga pāmahana whakawhiti (uara tata) Ac1=735℃, Ac3=855℃, Ar3=835℃, Ar1=680℃
(6) Whakaritenga Whakariterite Ko te pāmahana ko te 920 ~ 950 ℃, a ko te oumu he hau makariri. Ko te pakeke ko 131~156HBS.
(7) Whakatakotoranga mo te whakamahana i te maimoatanga o nga waahi makariri ko te 700 ~ 720 ℃, te wa pupuri ko te 8 ~ 15h, me te reiti whakamahana ko 50 ~ 100 ℃ /h, ka heke te pāmahana ki te 550 ~ 600 ℃ ki te oumu, a ka whakamatao te hau.
Ko te pakeke i mua i te maimoatanga ko ≤143HBS, a ko te pakeke i muri i te ngohengohe he ≤131HBS.
(8) Te whakamaaramatanga Whakamahana Temahana 910 ℃ ± 10 ℃, te whakamatao ki te 10% NaCl tote.
(9) Kua inehia te kaha tuku fy=245Mpa, te kōwae elastic E=206Gpa, te ōwehenga o Poisson ν=0.3.
(10) Ko te kaha o te kutikuti ko te 275 ~ 392MPa, ko te kaha o te kaha ko te 253 ~ 500MPa, ko te kaha o te tuku he 275MPa, ko te elongation he 25%.
(11) Ko te 600-650 nga nekehanga anake te pāmahana whakahiato, a ko te wa pupuri ko te 1-2h.
