Quenching Fluids and Salts Market Size

Quenching Fluids & Salts Market size was estimated at USD 2.3 billion in 2024 and is projected to attain USD 3.8 billion in 2037, surging at a CAGR of 4.3% during the forecast period i.e. 2025 to 2037. In 2025, the industry size of quenching fluids & salts is assessed at USD 2.4 billion.

The market is expanding rapidly globally as more industries are increasingly implementing the use of efficient heat treatment processes in automotive, aerospace, manufacturing, and metallurgical processing industries. For instance, in February 2023, Solar Atmospheres Inc. announced the approval of critical Boeing specifications for oil quenching of alloy steels in conformance with Boeing's specification BAC 5617.

Quenching fluids and quenching salts play a pivotal role in controlling the rate of metal parts cooling after the heat treatment process, increasing their hardness, strength, and durability accordingly. Increased demand for specialized quenching solutions that aim to produce superior material properties in the light of advanced manufacturing technologies, which include additive manufacturing and precision engineering.

This expansion is also supported by ever-increasing demands on high-performance materials in automotive, especially in lightweight components, as well as high-strength alloys. Environmental concerns and regulatory factors also are affecting the quenching fluids & salts market to foster more environmentally friendly and sound quenching fluids, including water-based and biodegradable ones. This added to the steady progress in heat treatment technologies, is likely to drive quenching fluids and salts in the future.
