Titanium vs Steel, What’s the Difference?

Steel and titanium are often the first materials that come to mind when designers think of strength and durability in their projects. These two metals come in a wide variety of alloys and are used for various applications. The difference between steel and titanium may not be easily recognizable unless you dig deep into their chemical and structural properties. In case you are wondering how these two metals compare, you are in the right place. This article takes on steel vs. titanium and explores the differences between them to help you understand the basics of each metal. 

What is Steel?

Steel is created by adding carbon to elemental iron. This process increases the hardness, strength, and resistance to impact, corrosion, and temperature. Steel has a wide variety of alloys that incorporate alloying elements like zinc, chromium, molybdenum, and silicon. These elements improve the ability of steel to resist corrosion, which is why it is mostly referred to as stainless steel. The amount of chromium added to steel determines its resistance to corrosion. It is hard to generalize the properties of steel since it exists in so many types and gauges.

 

To be specific, most alloys of steel are dense and hard but can still be worked. Steel also responds to heat treatment, which gives it different properties depending on the process and the type of steel. Additionally, steel is an excellent conductor of both heat and electricity. Some examples of steel are susceptible to rust because of the iron component. However, this problem is addressed by the addition of chromium to make stainless steel.
 

What is Titanium?

Titanium is the fourth most abundant metal on earth. However, it is infrequent to find titanium in elemental form or high concentration. Additionally, titanium is very difficult to purify, which makes it more expensive.
 
Titanium has a density of 4.51g/cm3, which means it lightweight compared to other metals. Additionally, a pure form comes in silver-grey color. It is essential to note that titanium is not magnetic. Like many metals, titanium can occur in an elemental form or a wide variety of alloys. These alloys are often strengthened and more resistant to corrosion. Most alloys of titanium are used in the aerospace, structural, and applications that require high-temperature resistance. Elemental titanium is often used as an alloying element.
 

Titanium vs Steel - What’s the Difference Between Titanium and Steel

 
Compared with steel, titanium has exceptional strength and weight ratio, and great biological compatibility, which makes it be the preferred material of surgical implants. Other common applications of titanium are aerospace and jewelry, this also related to its lightweight characteristics, high strength and corrosion resistance to a wide range of acids, alkalis, and chemicals. In automotive fields, steel is in strong competition with titanium, steel is preferred when strength is needed in a hard material, in addition, because iron is way more abundant than titanium, with less cost for the raw materials, steel is generally cheaper than titanium. In conclusion, here are some points describe the difference between titanium and steel. 
 
1. Titanium can withstand higher and lower temperatures than steel
 
2. Titanium is significantly stronger than the most commonly used grades of steel. But, the strongest known alloy steels in their strongest tempers are stronger than the strongest titanium alloys in their hardest temper.
 
3. In unalloyed condition, with the same strength, titanium is much lighter
 
4. Titanium is significantly more expensive than steel. Even though some grades for very specific applications may be sold at a price near that of titanium, most steels are very cheap compared to titanium. 
 
5. Titanium is less toxic than steel, experiences lower amounts of thermal expansion than steel and has a higher melting point .
 
6. Titanium has higher tensile stength per mass but not by volume. 
 
7. Steel is harder than titanium. Titanium deforms more easily than steel.
 
8. Steel is usually preferable for making strong objects as its volume is more acceptable.
