AISI 1340 alloy steel is used in recessed-head screws, high-strength bolts, machined components, socket screws, screws, construction applications and cap screws.
Introduction:
Alloy steels contain elements such as chromium, cobalt, nickel etc. These steels can be subjected to specific melting and deoxidization processes for particular kind of applications.
Alloy steels comprise a wide range of steels whose compositions exceed the limitations of Si, Va, Cr, Ni, Mo, Mn, B and C allocated for carbon steels. In comparison with carbon steels, alloy steels are a lot more responsive to mechanical and heat treatments.
