Quality Quench Bright 101
Quality Quench Bright 101
QUALITY QUENCH BRIGHT 101 is a clear, gold colored product designed to provide maximum cooling rates for austenitized steels. Its formulation guarantees good stability due to its accelerator package which will not stratify out at any temperature nor can it be filtered out. QUALITY QUENCH BRIGHT 101 can be used as a quench from temperatures as high as 1750°F and is especially suitable for developing maximum oil-quenched hardness in medium and low alloy steels. It is widely used as a quenching medium for carburized and carbonitrided work as well.
QUALITY QUENCH BRIGHT 101 is known as a fast quench oil, achieving rapid cooling rates in the nucleate boiling stage immediately following a short vapor phase. It also provides a slower cooling rate through the martensitic transformation range (Ms-Mf) than competitor’s fast quench oils. This ensures higher and deeper hardness levels are created without accompanying distortion of parts. Testing demonstrates QUALITY QUENCH BRIGHT 101’s superior heat removal characteristics are the difference between partial and complete hardening in actual practice.
Overall, distortion in oil quenched parts is proven to be caused by sluggish, non-uniform cooling rates. This is due to the thermal variations and mixed microstructures in the initial stages of the quench which slower quench oils produce. A fast uniform quench is especially important in batch-type carbonitriding furnaces to provide all portions of the load becoming evenly hardened. The quenching rate provided by QUALITY QUENCH BRIGHT 101 was designed to satisfy this requirement. Additionally, this low viscosity quench oil drains off parts quickly resulting in less drag-out and is characteristically easier to wash off work after quenching. If left on, it provides a thin film of protection from rust.
You can use QUALITY QUENCH BRIGHT 101 with confidence. Your parts will achieve maximum oil quenched hardness with minimum distortion or cracking. Lastly, QUALITY QUENCH BRIGHT 101 will produce exceptionally clean, bright work when used within its recommended temperature range.
OPERATION:
Bath Parameters
Temperature: 77 – 180oF (25 - 82°C) (open tank operation)
77 – 130oF (25 - 55°C) (vacuum operation)
200oF (93°C) Max (under protective atmosphere)
Velocity: > 100 FPM (0.5 MPS)
Immersion Time: As required for appropriate metallurgical transformation
EQUIPMENT:
Electrical immersion heaters used to raise the temperature of the oil should not exceed 10.0 watts per square inch in a well agitated environment.
CONTROL:
The quench speed of QUALITY QUENCH BRIGHT 101 can be obtained through testing by Quality Oil & Gas Co. Test method ASTM D6200 - Standard Test Method for Determination of Cooling Characteristics of Quench Oils by Cooling Curve Analysis is performed on as-used samples submitted by customers. If as - used QUALITY QUENCH BRIGHT 101 quench speed becomes slower resulting in lower hardness levels, a 5% addition of QUENCH OIL ACCELERATOR by volume of the quench system will restore the speed, increase hardness levels and reinforce the anti-oxidizing agent in the product. QUALITY QUENCH BRIGHT 101 may need centrifuging or filtering depending on sediment dragged into it during production.
Sediment level should be maintained at < 0.5%. Absorption of furnace atmosphere can cause the flash point of QUALITY QUENCH BRIGHT 101 to become lower than 340oF (171°C) resulting in poor quenching characteristics or create a possible fire hazard. Should this occur, de-gassing the oil at temperatures between 250 - 275oF (121 - 135°C) will remove the trapped gases. Agitation during the de-gassing process is recommended. All efforts should be made to avoid water contamination of QUALITY QUENCH BRIGHT 101, because it will cause very erratic quench characteristics as well as posing a serious fire hazard. Water contamination can be removed from the oil by slowly elevating its temperature to 250oF (121°C) for two hours with agitation.
