Ameralloy-13 is a chromium-molybdenumvanadium hot work steel with high vanadium
content which increases its wash resistance.
In addition, the alloy content minimizes heat
checking at high operating temperatures.
Ameralloy-13 is best used for long run zinc and magnesium die casting dies; also in forging, heading, and extruding applications where toughness, impact, strength and hot work steel qualities are essential. Ameralloy-13 requires a relatively simple heat treatment and can be quenched in air with a minimum of distortion. It may also be quenched in oil with satisfactory results.
Heating – Ac range 1600° to 1665°F
Cooling – Ar range 1460° to 1350°F
ROUNDS: Standard lengths 8’–10’ R/L. FLATS & SQUARES: Standard lengths 8’–12’ R/L. Specify O.D. and I.D. Modified and special sizes available upon request. Prompt forging service available.
When maximum hardness is the primary requirement, Ameralloy-13 may be oil-quenched. But keep in mind that when oil-quenched this grade is as vulnerable to cracking as and has the same distortional characteristics as an oil hardening tool steel.
