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

Fast, controlled quenching for better knife steel results

MR VOLCANO Parks 50 Quench Oil is engineered for shallow-hardening steels used in knife making and small shops. It delivers an initial water-like cooling, then slows through the martensite range to minimize cracking and warping, helping you achieve repeatable, clean hardening cycles.

How it helps your workflow

In practical terms, Parks 50 aims to balance speed with control. It is particularly effective for 1095, 1084, 1080, and similar steels, where a predictable cooling curve matters. Makers report consistent initial cooling with a reduced vapor blanket, which can translate to easier handling and fewer surprises in busy shop environments.

• Fast initial cooling like water at the start, followed by moderated cooling through the martensite range
• Lower risk of cracking and distortion compared with aggressive water or brine quenching
• Cleaner parts with less vapor blanket and reduced bath drag-out
• Simple to use in a 50–120°F bath; no special preheating required

Key specs and what to expect

• Nickel Ball time: 7–9 seconds at ~100°F (fast oil class)
• Recommended bath range: 50–120°F
• Flash point: >275°F
• Viscosity at 100°F: >5.8 cSt
• 1 gallon jug, Made in USA

Use cases and compatibility

Optimized for simple high-carbon steels (10xx family) and W-series (W1/W2). For air-hardening stainless or high-alloy tool steels, follow the steel maker’s recommended quench method, often plate or air cooling.

Care and safety

Use a properly sized quench tank and keep parts fully submerged until they are below flaming temperature. Do not overheat the bath beyond 120°F. Review the Safety Data Sheet and wear appropriate PPE and ventilation.

What makes Parks 50 a practical choice

• Ready-to-use, shop-friendly quench that supports repeatable hardness in target steels
• Designed to reduce vapor blankets and provide cleaner, more predictable results
• Compatible with common small-shop workflows and standard quench equipment
