Silver steel

Silver steel is common tool steel that is supplied as a centerless ground round bar (with tolerances similar to that of drill bit). The name comes from the highly polished appearance of the rods; there is no silver in the alloy.

Characteristics

In the annealed state it has a hardness of 27 HRC. It can be hardened to 64 HRC.[1]

Composition

The composition is defined by the British Standard BS-1407.

The European/Werkstoff equivalent is 1.2210 / 115CrV3, which also includes some vanadium.
