Quenching Oil
Quenching oil is a mineral oil-based cooling medium that, through the combination of base oils and additives, provides the cooling properties needed for ferrous metal quenching. It features excellent oxidation stability, long service life, and minimal deformation, making it suitable for various mechanical parts.
-
Polymer Quenchant
Polymer Quenchants are water-soluble solutions made from high molecular weight polymers with multiple functional additives. They offer controllable cooling performance and high environmental efficiency, ideal for heat treatment quenching of mechanical parts with strict environmental requirements.
-
Molten Salt Quenchant
Salt bath quenchant are formed from inorganic salts in different ratios, with relatively low melting points. Through process control, they achieve controllable cooling performance and enable martensitic or bainitic quenching. They effectively reduce workpiece deformation, suitable for martensitic graded quenching or bainitic isothermal quenching parts requiring high precision.
-
Blackening Agent
Blackening agent is a chemical used for metal surface treatment, primarily to form a black oxide layer on the metal surface. This process aims to provide rust and corrosion resistance as well as decorative effects, and it is applied to the surface treatment of various metal products.
-
Anti-Carburizing Coating
Anti-carburizing coatings are protective coatings designed to prevent carbon penetration in specific areas during metal heat treatment. They offer fast drying, resistance to peeling, environmental safety, and ease of application, making them suitable for large-scale or localized anti-carburizing treatments.
