IRON-NICKEL ALLOY HAVING IMPROVED WELDABILITY

摘要

The invention concerns an alloy made from iron comprising, by weight: 35% ≤ Ni ≤ 37%; traces ≤ Mn ≤ 0.6%; traces ≤ C ≤ 0.07%; traces ≤ Si ≤ 0.35%; traces ≤ Cr ≤ 0.5%; traces ≤ Co ≤ 0.5%; traces ≤ Mo < 0.5%; traces ≤ S ≤ 0.0035%; traces ≤ O ≤ 0.0025%; 0.011% ≤ [(3.138 x Al + 6 x Mg + 13.418 x Ca) - (3.509 x O + 1.770 x S)] ≤0.038%; 0.0003% < Ca ≤ 0.0015%; 0.0005% < Mg ≤ 0.0035%; 0.0020% < Al ≤ 0.0085%; the remainder consisting of iron and residual elements resulting from production.
