Stainless Steel is an alloy of iron with minimum chromium of 10.5%. On the surface of the steel chromium produces a thin layer of oxide which is known as 'passive layer'. And this helps to prevent any further corrosion of the surface. The increased amount of chromium gives an increased resistance to corrosion. Stainless Steel additionally contains varied amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other helpful properties like enhanced formability and increased corrosion resistance. Stainless Steel is combined with one or more elements in order to change its characteristics.
Titanium is a metallic element it has silver to grey color. It is an atomic number 12 and Ti is it symbol as a chemical element. Titanium alloy offers a high heat transfer efficiency and high resistant to corrosion. It also offers high strength-to-weight ratio, creating an extremely strong substance. Hence it is highly desirable where temperature changes and the elements of weather can create adverse effects on structural components, for example, in construction industries. Titanium alloy provides a high level of mechanical resistance which makes it extremely durable. The lightweight due to low density makes it desirable to certain industries. Its corrosion resistance is found across a wide field, which makes it highly resistant to corrosion created by a wide assortment of acids, alkalis, natural waters and industrial chemicals.
The main difference between stainless steel and titanium is simply that titanium is a metal while stainless steel is an alloy metal. Titanium's characteristics are naturally found within it, while stainless steel characteristics are created by adding alloying metals to it. For use in a specific project or activity circumstances exist that often suggest one substance is better suited than the other.
Stainless steel is preferred by industries that place a higher significance on weight than strength. It is highly suitable for specific industries, such as aerospace, an industry that requires lower density in addition to strength. Due to the unique qualities of titanium that deliver strength and durability along with low density it is often preferred by some manufacturers. Therefore titanium is often preferred when weight is a more important consideration than strength.
Titanium is more expensive than stainless steel which makes it cost-prohibitive for some industries where large quantity is required such as for construction. Therefore, when money is an important part of the equation, stainless steel is chosen over titanium if both substances are deemed suitable.
Titanium is extremely biocompatible, means that it is nontoxic to the human body. It is an excellent source for replacement parts such as knee replacements, hip implants, cases for pacemakers and craniofacial plates for the human body. Hence it is used regularly in the medical industry. It is also useful in the dental industry for dental implants, a growing area of the dentistry field. Titanium alloy is commonly used to make jewelry due to its biocompatibility and lightweight nature compared to stainless steel.
Stainless steel provides formability and weldability both, which allows it to be easily shaped. Stainless steel material is popular for use in a number of industries due to its shiny appearance. It is useful to make household items such as kitchen pans and pots, as well as to make healthcare products, such as portable carts, sinks, shelving, tables and countertops.
Titanium is highly resistant to fatigue caused by fluctuating changes in temperature, while stainless steel is subject to shattering and fatigue. Therefore, titanium is a better choice when variations in temperature lead to extreme highs or lows.
Titanium and stainless steel are used in many industries around the world. Both are highly strong, durable and corrosion resistant. Generally it is the nature of its use decides which metal is to be selected.
