NOTE: If you have problems with “tombstones” or unacceptable producttemperature variation, temperature stabilization should start at 5° to15°C below alloy solidus and end at 5° to 15°C above alloy solidus (10°to 30°C degree range). Ramp rate will usually need to be less than1°C. Thermally uniform product may require as little as 5 seconds, whilethermally diverse products may require over a minute.
