MR VOLCANO Parks 50 Quench Oil for Heat Treating Knife Steel – 1 Gallon

Effortless, Repeatable Quenching for Knife Steel

MR VOLCANO Parks 50 Quench Oil is a purpose-built quench oil designed to deliver a fast, water-like cooling at the start of the quench, then transition to a gentler pace as the steel enters the martensite range. This helps reduce common heat treating challenges like cracking and warping, especially with shallow-hardening steels such as 1095, 1084, and 1080, as well as W1 and W2. For many knifemakers and small shops, Parks 50 offers a predictable path to repeatable hardness without the unpredictability of a random oil or generic hydraulic fluid.

Why makers choose Parks 50

• Fast initial cooling plus a controlled slowdown: the oil starts like water, then moderates the cooldown to minimize distortion.
• Fast Oil class performance: Nickel Ball time of 7–9 seconds at ~100°F helps hit the early nose on common steels.
• Shop-friendly bath range: ready to use in a 50–120°F bath, often avoiding preheating while preserving speed and safety.
• Consistent, repeatable results: formulated for a stable cooling curve, lower vapor blanket, and cleaner parts with less drag-out.
• Convenient format: sturdy 1 gallon jug, proudly made in the USA, designed for regular use in small shops.

Practical use and care

Set up a properly sized quench tank and keep agitation active to ensure even cooling. Submerge your parts completely until they drop below the burning temperature of the oil. Do not allow the bath to overheat; stay at or below 120°F to maintain the intended quench speed and to enhance safety.

• Use with simple high-carbon steels (10xx family, especially 1095/1084/1080) and W-series steels (W1/W2) for best results.
• For air-hardening stainless or high-alloy tool steels, consult the steel maker’s quench recommendation—Parks 50 is optimized for the common well-behaved steels.

Safety and handling

Handle like any industrial quench oil. Review the Safety Data Sheet, use appropriate PPE, and ensure adequate ventilation. Potential hazards include eye or respiratory irritation and aspiration if swallowed. Store away from ignition sources.
