Del-Quench
Del-Quench™ Standard is a proprietary salt consisting of alkaline nitrate and hydroxide compounds. It is used as a post-nitride ‘quench bath.’ This neutralizes any potential toxic compounds which may have formed as a result of nitriding bath reactions reacting with any nitriding salt residues adhering to the components or fixtures. A second and perhaps more important function from a property and performance perspective is the formation of a uniform Fe3O4 black oxide layer on the part surface which greatly enhances the corrosion resistance, lubricity and cosmetic appearance.
The oxidizing Quench bath is integral to the Delamin QPQ® Nitriding process.
Del-Quench™ HN [Hign Nitrate Replenishment Salt] is a higher nitrate formulation of Del-Quench™ Standard quench salt. This is used as a supplemental addition to center the excessive salt drag-out during normal operation which tends to rapidly deplete the nitrate level below the recommended operating level of 5 % – 15 %.
Delamin® ST [Oxidizing Bath Starter Salt] is a proprietary quench salt used only when starting a new quench bath. It contains carbonate compounds in addition to the alkaline nitrate and hydroxide compounds contained in the Del-Quench™ Standard composition. It is used to prevent the cosmetic problems (red surface) associated with new quench bath start-ups.
