Unique for its strength, lightness of weight and corrosion resistance

Titanium fasteners are best known for being strong, lightweight, and corrosion resistant. They are critical to many industries including chlor alkali, marine, off-shore oil & gas, desalination, medical, and pulp and paper.  Grade 2 and 5 are the most commonly used grades of titanium screws:
•  Grade 2: Commercially pure titanium and the most common grade for screws.
•  Grade 5: Superior strength-to-weight ratio for a unique combination of corrosion and high strength.

Corrosion Resistance
Perhaps the most notable attribute of titanium is its superior corrosion resistance to salt water / seawater. Titanium screws have the unique ability to rapidly regrow their protective passive layer in the presence of oxygen, giving them unparalleled resistance to salt water environments.
•  Proven resistance in decades of polluted seawater
•  Usable in ocean depths of a mile beneath the surface
•  Resistant to high velocity, rapidly moving currents as well as stagnant seawater
•  Not affected by the presence of sulfides in seawater
•  Ideal for sea splash and tide zones
•  Seawater resistant to temperatures as high as 500°F (260°C)

Chloride, Chlorine & Other Media
Similar to salt water, titanium’s strong, protective oxide film which regenerates in oxygen makes it extremely resistant to oxidizing environments, and chlorides solutions, including hypochlorites, chlorates, perchlorates, sodium chlorite, and chlorine dioxide. This protection holds true as long as moisture is present – which can be as little as 50ppm of moisture. Oxidizing environments in the absence of water can cause titanium to rapidly corrode or even ignite. Titanium screws are not resistant to reducing media and acids (see chart).

Lightweight Strength
Not only are titanium grade 5 fasteners extremely strong, offering 148 ksi UTS and 138ksi yield they are also incredibly light. With a density of 4.51 g /cm3, titanium has on of the the highest strength-to-weight ratios available to industry. Titanium Grade 5 screws are 4 times stronger than 316 stainless steel at nearly half the weight. This makes titanium fasteners ideal for applications that require both lightness of weight and excellent strength such medical, military and sporting goods.
