The two fastest types of bolts that are usually selected when it comes to fastener selection are sequentially, Stainless Steel 316 and Titanium bolts. Plastic and glass have their own unique benefits which meet the requirement of a particular use; therefore, it is essential to determine between two materials. This blog aims at explaining the various differences between SS 316 and Titanium bolts and enable the reader come up with the right decision concerning the two.
Corrosion Resistance
Another important specification that one usually loves to compare while choosing between the SS 316 and Titanium bolts is their ability to stand up to corrosion. The SS 316 bolts are particularly valued for their corrosion resistance especially in application that involve high chloride content like the marine applications. This is because molybdenum gives the alloy a very strong resistance on corrosive features as compared to other steels.
None the less, titanium bolts take corrosion resistance even to another level of its already high capability. Titanium by its nature withstands most kinds of corrosion irrespective of the conditions prevailing in normally unfavourable environments. Titanium reacts with oxygen in the air to form an oxide film on the surface which checks further oxidation and corrosion. Titanium bolts are used in aerospace applications, chemical processing and subsea hardware and equipment.
Strength and Weight
In the aspect of strength, Titanium bolts are the stronger ones. Titanium is known for their high strength to weight ratio and are stronger than most of the bolts but considerably lighter than Stainless Steel 316 bolts. This makes titanium suitable to be used in organizations that require weight be minimized such as the aerospace industry and high-performance vehicles.
Even though more massive, bolts of the SS 316 variety have great tensile strength and are capable of handling pressure and temperature. These are varieties, which apply mostly in construction business, in marine industry and chemical industries where strength and endurance is very important.
Cost Considerations
Of all the factors that are can be used to compares these two materials, cost is usually the main one used. The Stainless Steel 316 bolts are cheaper in most cases and preferred for many uses. Titanium bolts, however, cost more than both hex bolts and hex cap screws because they take time to manufacture and they possess special features.
Despite Titanium bolts demanding higher price, the features that accompany it may in fact be an advantage for their use where weight is an issue and where high corrosion resistance is required.
Application Suitability
SS 316 bolts are versatile and are commonly used in:
- Marine environments, due to their resistance to chlorides
- Chemical processing industries
- Construction projects where durability is key
Titanium bolts are best suited for:
- Aerospace and aviation industries, where weight and strength are critical
- Medical applications due to their biocompatibility
- Subsea and chemical environments where extreme corrosion resistance is needed

Summary
In general, decision whether to use SS 316 bolts or Titanium bolts depends on the particular project. Stainless Steel 316 bolts has turned out to offer value for money as a material possessing high resistance to corrosion as well as strength, for most uses. However, if your project requires high tensile strength, and the bolts have to stand up to aggressive environments that will corrode other common fasteners, even at a higher price, Titanium bolts will suffice best.
To sum up, for the common purpose and more specifically for any application where there is a potential for corrosion, SS 316 bolts are preferable, and for the high end applications where weight, strength and resistance to corrosion are paramount, the Titanium bolts. Ensure you analyze your project to determine the best fastener that can be used to ensure the project is completed as desired.
