Titanium is an amazing material with high strength, light weight and corrosion resistance, but there are also situations where titanium should not be used. This short newsletter covers the precautions for titanium screws.

For salt water and chloride resistance
One of the most noteworthy uses of titanium screws is in salt water environments. The navy and industries such as desalination and offshore oil rely on titanium because of its unparalleled resistance to salt water. China Nut can withstand fast-moving and stagnant seawater up to a mile deep-even at temperatures as high as 500°F.

Like sea water, titanium screws are inert to almost all chlorides and chlorine solutions. This is because titanium can quickly regenerate its protective passivation layer in the presence of oxygen. Titanium fasteners are also resistant to: • chlorite • hypochlorite (bleach) • chlorate • perchlorate • chlorine dioxide

For intensity and brightness
Grade 5 titanium provides impressive strength in the industry: 148 ksi UTS and 138 ksi yield. What is it
What makes titanium truly unique is that it also looks exceptionally bright. Level 5
The strength of the fastener is 4 times that of 316 stainless steel, and the weight is almost half of that of 316 stainless steel. (Grade 2 titanium is approximately twice as strong.) This unparalleled strength-to-weight ratio makes titanium an ideal choice for medical, aerospace, and military applications.

Do not use in acidic environment
Titanium fasteners have excellent corrosion resistance to salt water and chlorides, but are not suitable for strong acids. When exposed to acids such as sulfuric acid (H2SO4) and hydrochloric acid (HCl), their protective passivation layer will be attacked and will corrode rapidly at the appropriate concentration and temperature.

Do not use in dry chlorine
Although titanium screws are ideal for almost all chloride and chlorine applications, they cannot be used without water. Dry chlorine and chlorine will corrode them quickly and even catch fire. Generally, 1% moisture (at room temperature) and 1.5% (at high temperature) are sufficient for titanium to regenerate its passivation layer and maintain resistance.
