Titanium has many beneficial properties. It has a high strength to weight ratio, increased fatigue resistance and is non-magnetic. Like other metals, it is available in different strength levels depending on the alloy. Several alloys are NACE MR0175/ISO 15156 certified for use in sour gas applications.
