How hard is invar
Web21 mrt. 2024 · La lega INVAR, l'abbreviazione di invariabilità, composta da 64% Fe, 36% Ni e pochi altri elementi come S, P e C, ha un coefficiente di espansione lineare molto basso inferiore a 100 ℃, noto anche come acciaio a bassa espansione, si trova in primo luogo dal fisico francese CEGuialmeI nel 1896. WebThe second is a variation of the basic alloy known as Free-Cut Invar "36"® alloy (UNS K93050 and ASTM F1684). This alloy has shown improved machinability for applications where high productivity is important. It is also a 36% nickel-iron alloy, but with a small addition of selenium (Fig. 1) to enhance machinability.
