2.4658 (DIN 17742 : 2020-12) NiCr7030 2.4658 DIN 17742 : 2020-12 Supersedes DIN 17742 : 2002-09 Valid Germany NiCr7030 3.4 ≤ 1200 1)
1) Remark: NiCr alloy for furnace components and heating conductors. It is an austenitic nickel-chromium resistance alloy. It is characterised by good scaling resistance as well as resistance under alternating stress in oxidising/ reducing atmospheres, for operating temperatures up to 1250 °C. Use for industrial electric furnaces, enamelling furnaces and night storage furnaces. Formability: good Weldability: satisfactory
