Abstract
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+2×Co≦20%; 0%≦Mn+Cr<5%; 0%≦W+2×Mo≦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.
