Kuramba Kupisa Kwakanaka NiCr 70/30 yeTambo dzeKupisa

Tsananguro pfupi:

NiCr 70/30 (2.4658) imhando ye austenitic nickel-chromium alloy (NiCr alloy) inoshandiswa pakupisa kusvika ku1250°C. Iyo 70/30 alloy inoratidzwa nekusimba kwakanyanya uye kuramba kuoxidation zvakanaka. Ine ductility yakanaka mushure mekushandiswa uye kugona kusundira zvakanaka.

    NiCr 70/30 (2.4658) inoshandiswa pakupisa zvinhu zvemagetsi zvinodzivirira ngura mumaovheni emaindasitiri ane mhepo inodzikisa. Nickel Chrome 70/30 inodzivirira zvikuru oxidation mumhepo. Hazvikurudzirwi kushandiswa muMgO sheathed heating elements, kana kushandiswa uchishandisa nitrogen kana carburizing atmospheres.
