Comparison Between Titanium Tubes and Stainless-Steel Tubes

A titanium tube is considered as high-strength and at the same time low-density metal too. Therefore, it is quite suitable for applications where both strength and weight are very much critical.

Stainless steel tube on the other hand is highly resistant to corrosion and can protect against high temperature. It also has an appearance that can be aesthetically appealing. For various range of structural application, stainless steel is used due to its excellent machinability and weldability. In this small write-up, we will talk about the difference between titanium pipes and stainless-steel pipes. You can find more information here.

Saving in weight and space

As compared to steel, titanium is approximately 45% lighter. Another difference is that titanium can easily withstand high temperature without any weight reduction.

Higher tensile strength and hardness 

Titanium is almost 56% dense with a density of 4.54 grams/cc. During hardening of this metal, oxygen is absorbed in the titanium surface when this metal is hardened.

Titanium and its various alloys have a tensile strength in the range of 20,000 psi to 200,000 psi. any commercial grade titanium has got the tensile strength of around 63,000 psi. Commercially pure titanium which is the softest grade having this figure around 240 MPa, though any high-strength alloys may go up to 1,400 MPa.

Complex applications

Titanium tubing being biocompatible and nontoxic, it is often used for more complex and challenging applications e.g. orthopaedic implants or surgical instruments. Due to its high ratio between tensile strength and density, titanium and its high corrosion resistance can make it an ideal material for aerospace and sensitive military applications, including firewalls, aerospace critical structural works, landing gear and exhaust ducts.
