Oxygen Oxygen rollover Oxygen

With the power to lower costs and improve productivity, oxygen is an essential component in steel production.

Argon Argon rollover Argon

A key component in our Argon Oxygen Decarburization technology, argon is used to create over 75% of the world’s stainless steel.

Nitrogen Nitrogen rollover Nitrogen

Used as a key component in the heat-treating process, nitrogen is also used in Argon Oxygen Decarburization for stainless steel refining.

Hydrogen Hydrogen rollover Hydrogen

Hydrogen is used to prevent oxidation and is the key component in the heat treating process.


Not only used for stainless steel but specialty alloys such as silicon steel, tool steel and nickel-based alloys, our Argon Oxygen Decarburization process minimizes the loss of precious elements during production.

Our state-of-the-art oxygen injection system, CoJet® Gas Injection, is a leading technology for burners, lancing and post-combustion in electric arc furnaces because it lowers costs and increases productivity.

Introduce our Dilute Oxygen Combustion technology into your ladle preheating process and reheat furnaces for faster heat times with less fuel and reduced emissions.

Whether you need hydrogen or nitrogen-based atmospheres, we provide cost-effective, high-productivity heat-treating processes to help you achieve precise, reproducible results.

Our Laminar Barrier Inerting technologies improve your product quality by reducing alloy oxidation, slag formation and defects.
