QUENCH FLUID 4536
It is a fluid, made by a concentrated watery solution of polyalkyleneglycol, free from nitrates, in mixture with anti-corrosive additives, anti-rust, stabilizing and biocides, particularly formulated for quench of ferrous alloys.
QUENCH FLUID 4536 has a wide purpose flexibility, as it can be used with different water concentrations, with different quench speeds.
It ensures:
- Maximum safety grade, as the fire risk, smokes formation and oil mist formation are eliminated;
- Excellent stability of the watery solutions in a wide concentration range;
- Excellent anti-rust properties, thanks to the use of a balanced and selected raw materials and components system;
- Considerable cleaning grade of the worked pieces;
- Stress and distortion reduction of the worked materials, thanks to the control of the cooling speed in the most delicate phases of the quench process.
Application
QUENCH FLUID 4536 can be used in quench of forged or pressed ferrous materials. It can be used in open tanks, in continuous furnaces, in ovens for integral quenches and selective or superficial heat treatment plants.
N.B. QUENCH FLUID 4536 can be used in order to substitute quench oils or to improve the present quench operations. In these case, we recommend to ask out Technical Assistance Service for the best choice of the in-use concentrations.

QUENCH SP 15
E’ un olio per tempra metalli a caldo ed isotermica, ottenuto da una base minerale paraffinica severamente raffinata al solvente. L’additivazione è di alto livello qualitativo e garantisce un’eccellente costanza della drasticità di tempra al variare della temperatura del bagno d’olio. Ciò consente di conseguire i seguenti vantaggi:
- Accelerare la velocità di tempra, per poter produrre componenti di maggior durezza o per poter utilizzare acciai più economici;
- Proprietà costanti ed uniformi dei pezzi trattati;
- Formazione di morchie ridotte, per ridurre le esigenze di manutenzione dell’impianto e le perdite di olio;
- Minima formazione di acidi per evitare la macchiatura dei componenti e per incrementare la stabilità all’ossidazione dell’olio;
- Alta resistenza alla formazione di cricche ed alle distorsioni negli acciai trattati, per incrementare la flessibilità nella progettazione dei componenti;
- Massima compatibilità igienico-sanitaria ed ambientale, con fumi ridotti ai minimi livelli, grazie anche all’elevato punto di fiamma della base.
In definitiva il tipo di additivazione e la qualità dell’olio base impiegati consentono di ottenere un olio per tempra a base minerale di alte prestazioni, resistente al decadimento termico-ossidativo e ad buon potere detergente per la pulizia del sistema.
Applicazione
Olio per tempra di acciai al carbonio e legati, a base minerale, di massimo livello qualitativo per temperature di esercizio che superano i 100 °C fino a 150 °C.

QUENCH SP 150
It is a metal quench oil, made from a mineral paraffinic base, highly solvent refined.
The high-quality additivation ensures an excellent regularity quench severity when the oil bath temperature changes.
It ensures the following advantages:
- Speeded up quench velocity, in order to produce stronger components or to use cheaper steels;
- Constant and uniform properties of the worked pieces;
- Reduced sludge formation, in order to reduce the maintenance needs of the plant and the oil loss;
- Minimum acid formation, in order to avoid components spotting and to increase the stability at the oil oxidation;
- High resistance to cracks and distortion formation in the treated steels, in order to increase the flexibility in component design;
- Maximum hygienic-sanitary and environmental compatibility, with reduction of smokes, thanks to the base high flash point, too.
Definitively, the additivation type and the base oil quality used allow obtaining a mineral-based quench oil with high performance, thermic-oxidative decay resistant and with a good detergent power for the cleaning of the system.
Application
Quench oil for carbon and alloyed steels, mineral-based and high quality for temperature up to 150°C.

QUENCH SP FS 32
It is a metal quench oil with the following features:
- Very high thermic stability: the oil is well protected against temperatures jumps, which could cause linkages molecular breaking and so the well-known “cracking”;
- High oxidation resistance: the oil, through an adequate additivation, is able to hold the chemical attack caused from the shaking when there is oxygen (air), although it will form slush, sludge, carbon residual;
- Very high quench drastic, thanks to particular “wetting” additives, which increases the lubricant adherence on the worked pieces and so decreases the vapor layer created by the same liquid on the hot metal surface and bad heat conductor (calefaction);
- Excellent quench drastic constancy when the oil bath temperature changes.
The quench oil has to keep the most homogeneous as possible in every fluid mass point, in order to steal heat continuously and quickly. The heat is both from the exothermic transformation of the crystallization and from the inside, which recovers the external surface of the metal. In this way, the piece achieves uniformly the required hardness, elasticity, breaking load, ecc. characteristics, even if it is irregular.
For all the above-mentioned characteristics, QUENCH SP FS 32 belongs to the category “long life quenching oils” which keep their performances quite unchanged during the most severe working conditions.
Application
Quench of steels with low, medium and high hardenability, even with irregular shape and important thickness. QUENCH SP FS 32 is used generally in the temperature range 40 ÷ 60 °C but it can also be used in the range 80 ÷ 100 °C without relevant changes in its quench and refrigerating characteristics.
