Nickel Chromium Heat Resistance Alloy Waea Hiko 2080/3070
HNickel Chromium wera wera whakarewa waea hiko 2080/3070
Ko nga waea Nickel-Chrome e whakamahia nuitia ana hei koranu aukati teitei mo te whakawera hiko me nga parenga waea-whaea i roto i te umanga whakarewa, te umanga matū me te umanga hiko, aha atu.
Ko tenei waea koranu he teitei ake te whakareatanga hiko, he pai te mahi anti-oxidation me te mahi anti-corrosion, he pai hoki te mahi miihini me te weldability, me te kaha nui i te teitei teitei.
Ko nga ahuatanga matua o te Ni-Cr me te Ni-Cr-Fe nga hiko whakawera hiko
