Titanium, known as the "space metal" and "biophilic metal", is constantly expanding the boundaries of industrial design with its unique combination of properties. In harsh environments, the choice of a screw may determine the lifespan and safety of the entire system. Whether it is a wind power platform facing seawater, a chemical pipeline with strong acidity and alkalinity, or a medical device implanted in the human body or a high vibration aircraft, fasteners are not only connectors, but also a key part of the engineering defense system.
Titanium screws vs. stainless steel screws
This is the most common multiple-choice question faced by engineers and procurement. The fundamental difference between titanium screws and stainless steel screws lies in their material properties, which directly determine their application scenarios.

|
|
| feature | Titanium screw(Gr1 Gr5) | stainless steel screws(316L 316N) |
| Density and weight |
Lightweight advantage: 43% lighter The density is about 4.5g/cm ³, which is about 43% lighter than stainless steel |
Traditional Durable Density of approximately 7.9g/cm ³ |
| specific strength | ⭐ extremely high The strength performance per unit weight is superior to most alloy steels and stainless steels |
good High strength, but lower specific strength than titanium alloy |
| corrosion resistance | ⭐ excellent Especially resistant to chloride ion corrosion (such as seawater, saltwater), almost rust free |
good But pitting corrosion may still occur in chlorine containing environments |
| biocompatibility | ⭐ excellent Non toxic, non allergenic, acceptable to the human body, widely used for implantable devices |
general Some individuals may be allergic to nickel ions and are not suitable for implantation in the body |
| non-magnetic | Completely non-magnetic | Usually non-magnetic or weakly magnetic Austenitic stainless steel (such as 304, 316) |
| cost | higher High raw material and processing costs |
Relative economy |
| Applicable scenarios | Medical equipment, marine engineering, chemical equipment, aerospace, high-end outdoor equipment | Food equipment, general construction, general industrial household appliances |
