Ameralloy-13

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.

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.

Tempering For hot work applications, Ameralloy-13 is used in the hardness range of HRC 38–48. The usual hardness range for die casting dies is HRC 44–48, requiring a temper at approximately 1100°F. For improved shock resistance, the steel is often tempered at temperatures approaching 1150°F, resulting in a hardness range of HRC 40–44. The steel should be held at tempering temperature for at least 2 hours per inch of greatest cross section. All hot work steel should be tempered at a minimum of 50°F above the expected maximum operating temperature of the tool or die. Double tempering, with the second temper 25°–50°F lower than the first temper, is always advisable, particularly where heat checking is a problem.

Above results on 1” diameter specimens may be used as a guide in tempering tools to desired hardness. Tools of heavy section or mass may be several points lower in Rockwell hardness for a given treatment.

General Instructions

Forging Large pieces of Ameralloy-13 should be preheated slowly to 1300°–1500°F, and thoroughly soaked before heating rapidly to the forging temperature of 2050°–2150°F. The steel should be thoroughly heated before beginning the forging operation. Do not forge below 1650°F, but reheat as many times as necessary. After forging is completed, the steel should be slowly cooled by burying in a heat-insulating material such as dry ashes, lime, or vermiculite.

Annealing Ameralloy-13 may be annealed by heating to 1600°F. Soak 1 hour per inch of greatest thickness, and furnace cool at 30°F per hour to 900°F. Then air cool. Proper annealing procedure includes packing in a steel container using a neutral inert material. Maximum Brinell hardness of 207.

Hardening In a controlled atmosphere, preheat thoroughly to 1300°–1400°F. Then heat to 1850°F and hold for 1 hour per inch of greatest cross section. Quench in still air and temper immediately.
