Fe-ni or fe-ni-co or fe-ni-co-cu alloy strip with improved cuttability

摘要

Strip made of an austenitic Fe-Ni alloy or Fe-Ni-Co alloy or Fe-Ni-Co-Cu alloy, the chemical composition of the alloy of which comprises, in % by weight: 30%<=Ni<=70%; 0%<=Cu+2xCo<=20%; 0%<=Mn+Cr<5%; 0%<=W+2xMo<=2%; 0%<=Ti+V+Nb+Al<=1%; 0.0005%<=B<=0.007%; the balance being iron and impurities such as C, S, P, O and N; the chemical composition being such that Fe+Ni+Cu+Co>=95%. The alloy has a cubic texture with a cubic texture index Dc>=7. Process for manufacturing a strip. Process for manufacturing a part by mechanical cutting.
