Air Liquide in India Metal Treatment & Fabrication

Deep Cryogenic Treatment (DCT)

Air Liquide’s ALNAT™ DCT solution treats components through exposure to temperatures below 150 degrees Fahrenheit. Benefits of ALNAT DCT include increased resistance to wear, abrasion, pitting and spalling while reducing residual stress for a longer use life. The ALNAT DCT solution will help ensure a controlled atmosphere providing safety, efficiency and reliability.

Heat Treatment

Air Liquide’s extensive technical knowledge of heat treatment processes, coupled with our safe, reliable and customized gas solutions, will help you optimize your operations and manage costs. ALNAT™, Air Liquide’s dedicated offer for heat treatment applications, includes the delivery of gases and gas handling equipment as well as a range of services relating to the generation, use and control of atmospheres in industrial heat-processing furnaces. Air Liquide also produces various hydrogen gas mixtures in a wide range of balances and packaging options, and all related gas handling equipment. These gas mixtures are used specifically to modify structure characteristics of steel, such as hardness and flexibility.


In addition to industrial gases for heat treatment applications, Air Liquide’s Scott™ brand specialty gas mixtures are used specifically to modify the structure characteristics of steel, such as hardness and flexibility. We engineer hydrogen gas mixtures in a variety of balances and packaging options for steel and heat treatment.
