FeNi Nickel Iron koranu tika 0.5mmInvar 36 Waeamo te Hiri Taputapu Taputapu
INVAR 36he nickel-rino, iti roha koranu kei roto 36% nickel. Ka mau tonu nga Ahua i runga i te awheawhe o te rangi o te hau, he iti te whakarea o te roha mai i te pāmahana cryogenic ki te 500° F. Ko te koranu ka mau tonu te kaha me te pakari i nga pāmahana cryogenic.
INVAR 36ka taea te hanga wera me te makariri me te miihini ma te whakamahi i nga tikanga rite ki
kowiri tira austenitic. INVAR 36 he weldable te whakamahi Filler Metal CF36 which is
e waatea ana i roto i te waea kore mo te tukanga GTAW me te GMAW.

Te tukanga maimoatanga wera | |
Te whakahiato mo te whakamau i te ahotea | Whakawerahia ki te 530~550ºC ka pupuri 1~2 haora. Te makariri |
whakapouri | I roto i te tikanga ki te whakakore pakeke, e kawea i roto i te matao-hurihia, tukanga tuhi matao. Me whakamahana ki te 830~880ºC i roto i te korehau, kia 30 meneti. |
Te tukanga whakapumau | I roto i te whakamarumaru me te whakamahana ki te 830 ºC, pupuri 20min. ~ 1h, tineia Na te ahotea i puta mai i te tinei, ka wera ki te 315ºC, pupuri 1~4h. |
Whakatupato | Kaore e taea te whakapakeke i te maimoatanga wera Ko te maimoatanga o te mata ka taea te kirikiri kirikiri, te whakakoi, te pikike ranei. Ka taea te whakamahi i te koranu 25% wairewa waikawa waikawa maatai i te 70 ºC hei whakawātea i te mata waikura. |
