Ātete Pai ki te Waikura NiCr 70/30 mō ngā Taura Whakamahana

Whakaahuatanga Poto:

Ko te NiCr 70/30 (2.4658) he koranu nikara-konukōmiuma austenitic (koranu NiCr) hei whakamahi i ngā pāmahana tae atu ki te 1250°C. He teitei te ātete o te koranu 70/30, ā, he pai hoki te ātete ki te waikura. He pai te ngāwari o te whakarewa i muri i te whakamahinga, ā, he tino pai te āheinga ki te whakarewa.
