Oxygen (O2), which comprises 21% of the earth’s atmosphere, supports life and makes combustion possible. Colorless, odorless and tasteless, oxygen is used to support oxyfuel cutting operations. Oxygen may be added in small quantities to shielding gases. Oxygen is also used as the plasma cutting gas (with Hafnium electrodes) on carbon steel.
O2
Oxygen (O2) – constitutes approximately 21% of the air we breathe. Oxygen can be stored and shipped as either a gas or a cryogenic liquid.
Applications
The principal uses of oxygen are indicative of its strong oxidizing and life-sustaining properties
It’s used in medicine for therapeutic purposes and in the metals industry for steel-making and metal-cutting applications.
