Blackening Salt
Dhatukarm’s Annealing Heat Treatment Salts are expertly formulated to deliver precision-controlled thermal processing across a wide range of ferrous and non-ferrous metals. These salts create a non-oxidizing, uniform heating environment ideal for stress relieving, spheroidizing, and soft annealing. With excellent heat transfer properties and stable thermal performance, they prevent surface scaling and decarburization while ensuring consistent metallurgical results. Commonly used in industries such as automotive, aerospace, electrical, and forging, Dhatukarm’s annealing salts offer low sludge generation, broad temperature adaptability, and easy maintenance. Backed by deep technical expertise and a commitment to customization, our solutions ensure improved part quality, energy efficiency, and smoother operations in every heat treatment cycle.Our annealing salts are engineered to provide exceptional thermal consistency across both batch and continuous processing systems. They are suitable for annealing of tool steels, carbon steels, alloy steels, copper alloys, and other critical components requiring controlled microstructure development. These salts help refine grain structure, reduce internal stresses, and restore ductility in metals, thereby enhancing formability and machinability for downstream operations.
