Titanium and stainless steel are both traditional metals used in the manufacturing industry today. Both of these metals are inherently excellent and both have a unique set of properties and strengths. As a result, knowledge of both titanium and stainless steel can go a long way in helping you achieve your goals on your project. We have created this comprehensive guide to help you distinguish between the two metals.
What is Titanium steel?
The metallic element, titanium, is silver-gray in color. Its atomic number is 22, and its symbol is T as a chemical element. It gives a high strength weight ratio, making it an extremely strong substance. The titanium also offers high heat transfer efficiency as well as being extremely resistant to corrosion. As a result, it is highly desirable for use in some industries, such as construction, where changes in temperature and weathering can have an adverse effect on structural elements.
Titanium provides a high level of mechanical resistance, which makes it extremely durable. Its low density makes it lightweight, increasing its desirability in some industries. Its corrosion resistance is found in a wide area, which makes it highly resistant to corrosion caused by a wide assortment of salts, acids, industrial chemicals, and natural water.
What is stainless steel?
Stainless steel is alloy steel, which means that it is still attached to one or more elements to change its characteristics. Alloying refers to the process of mixing more than one metal together. In the case of stainless steel, it is made with about ten to thirty percent chromium and seventy percent iron to give almost rough resistance as well as the ability to withstand temperature changes well.
When other elements are added to the alloy, it is usually done to increase the steel’s ability to resist corrosion or oxidation. In some cases, a special element is added to promote the specific characteristic of certain types of stainless steel. Although they are not always added to alloy steel, one or more of the following elements are sometimes included in alloys of metals: titanium, copper, aluminum, sulfur, nickel, selenium, niobium, nitrogen, phosphorus, or molybdenum. The specific metals that are added to steel to make stainless steel are known as alloying elements.
Let’s compare the differences between titanium and stainless steel
Titanium and stainless steel show excellent characteristics that distinguish both from each other. For easy understanding, we will draw a comparison between titanium and stainless steel using different properties. These properties include basic composition, corrosion resistance, electrical conductivity, thermal conductivity, melting point, hardness, weight, and many more.
Titanium vs. Stainless Steel: Element Composition
Element composition is a characteristic that can be used to differentiate between titanium and stainless steel. In comparison, commercially refined titanium contains a variety of elements, including nitrogen, hydrogen, oxygen, carbon, iron, and nickel. Since titanium is the main element composition, the other elements vary in percentage between 0.013 and 0.5.
Stainless steel, on the other hand, is composed of 11% chromium with elemental composition varieties as well as other elements with a percentage composition of 0.03% to 1.00%. The chromium content of stainless steel helps prevent rust and also provides heat-resistance characteristics. These elements include aluminum, silicon, sulfur, nickel, selenium, molybdenum, nitrogen, titanium, copper, and niobium.
Titanium vs Stainless Steel: Corrosion
When it comes to corrosion-related applications, there is a term called specialty metals. These specialty metals are highly corrosion-resistant metals. In this regard, special metals such as titanium provide high corrosion resistance and mechanical stability where stainless steel and many other metals are inadequate. Stainless steel material offers excellent mechanical properties; However, their corrosion resistance is limited. This limitation is most often found in concentrated acids at concentric temperatures.
Specialty metals such as titanium are attractive for use in corrosion-sensitive devices in most industrial varieties. In conclusion, titanium is more corrosive than stainless steel in a wide area such as corrosion against salts, acids, natural water, and industrial chemicals.
Is titanium stronger than stainless steel Which is stronger?
When bonded with other metals such as aluminum or vanadium, titanium becomes dramatically stronger than many sheets of steel. In terms of shear strength, the best titanium alloys beat lower to medium grade stainless steel. However, the highest grade of stainless steel is stronger than titanium alloy. If you are looking for strength, we recommend sticking with ordinary titanium alloys.
Which is lighter?
Given its strength, titanium is remarkably light. When compared to steel by weight in terms of strength, titanium is superior, as it is as strong as steel but 45% lighter. In fact, titanium is the most potent weight of all known metals.
Titanium vs. Stainless Steel: Electrical Conductivity
Electrical conductivity involves the flow of electrons through a material due to a decrease in potential. Also, the molecular structure of such a metal contributes strongly to its electrical conductivity. Compared to using copper as a standard for measuring electrical conductivity, titanium is not a good conductor. It shows about 1.1% conductivity of copper while stainless steel copper has 3.5.% conductivity.
From another point of view of electrical resistance, the opposite of which is physical performance in the flow of electrons. From this point of view, titanium exhibits poor conductivity. Consequently, titanium is a suitable resistor.
Titanium vs Stainless Steel: Thermal Conductivity
Thermal conductivity is another characteristic that can be used to draw comparisons between titanium and stainless steel. Thermal conductivity is a measure with which titanium and stainless steel can be used for thermal application. In this process, the amount of energy released as well as the rate at which energy is absorbed and transferred is measured and determined. In comparison, titanium has 118 BTU-in / hour-FT-3F rated thermal conductivity.
Stainless steel, on the other hand, has a thermal conductivity ranging from 69.4 to 238 btu-in / hour-ft: ° f. This translates to the fact that stainless steel exhibits higher thermal conductivity than titanium. In cases where the thermal conductivity is higher than other characteristics, stainless steel can be considered.
Titanium vs Stainless Steel: Melting point
The melting point of a material known as the melting point is the temperature at which such material begins to move from the solid phase to the liquid phase. At this temperature, the solid phase of the material and the liquid phase of such material remain in equilibrium. Once the material reaches this temperature level, it easily forms and can be used for thermal application.
Is titanium harder than stainless steel, titanium vs stainless steel hardness
The hardness of the material is a comparable value that helps to describe the response of such material to etching, deformation, itching, or dentition on the surface of the material. This step is mostly done using intensive machines that exist in a wide variety depending on the strength of the material. For high-strength materials, manufacturers or users use the Brinell hardness test.
The brine hardness of stainless steel varies greatly with alloy composition and heat treatment, it is harder than titanium in most cases. However, titanium deforms easily when accented or scratched. In a bid to avoid this, titanium forms an oxide layer called the titanium oxide layer which forms an exceptionally hard surface that resists most forces. Titanium and stainless steel are both resistant materials that work great when exposed to bearing and rough environments.
Titanium vs. Stainless Steel Weight
An important difference between titanium and stainless steel is their density. Titanium has an excellent strength relative to weight, giving it the same strength as 40% of its weight in stainless steel. When measured, titanium is half dense like steel, and it is significantly lighter than stainless steel.
As a result, titanium is important for projects that require a minimum weight with maximum strength. This is the reason why titanium has excellent application in aircraft parts and other weight-based applications. On the other hand, steel is applied to the vehicle chassis and many more but most weight loss is often a concern.
The use of titanium
Due to its impressive strength-to-weight ratio, titanium alloys are always used in strong products that require light, such as tennis rackets and bicycles. However, it is also used in ship holes and propeller shafts due to its seawater resistance. In the case of metal plating, electroplating services can be applied to titanium, for example, platinum can be added to improve its appearance.
Use of steel
Stainless steel is widely used in modern construction because it is hard, flexible, and easily welded. Steel is also used in products with blades such as knives, as they are harder than titanium. Blades made from high-grade steel last longer than titanium blades. This is because steel always takes longer to deform than titanium. In terms of metal finishing, stainless steel can be deactivated to reduce the chemical reaction of its surface. It can also be used as parent metal and is covered with metal plating
