At 700 degrees F it acquires a light straw color.
Titanium resists atmospheric corrosion.
Caution should be exercised in using titanium in high oxygen atmospheres. Under some conditions, it may ignite and burn. However, once the reaction has started, it will propagate in atmospheres with much lower oxygen levels than are needed to start it. Steam as a diluent allowed the reaction to proceed at even lower O2 levels. The temperature, oxygen pressure, and concentration limits under which ignition and propagation occur are shown in figures 13 and 14 .
