What is Stainless Steel
Stainless steel is one of the most well-known metals with numerous applications across various sectors due to its properties, such as rust resistance and stain resistance. Stainless steel was accidentally discovered by adding chromium to iron. When comparing stainless steel to other alloys like iron and steel, it has advantages that we will explore, including the characteristics of each metal and their differences below.
What is Stainless Steel, Its Types, and Uses
There are different types of stainless steel. The variation in stainless steel depends on its different components. Therefore, we will explain the types of stainless steel as follows:
Austenitic Stainless Steel
This is the most common type, containing a high percentage of nickel along with other elements like nitrogen, chromium, and molybdenum. It is weldable, flexible, and strong, with excellent corrosion resistance. It is used in making kitchen tools; however, it is expensive. The common austenitic stainless steel alloys are 304 and 904L (N08904).

Ferritic Stainless Steel
This type contains a small amount of carbon (about 0.10%) but has a high content of chromium and molybdenum. It is rust-resistant, highly magnetic, and has significant corrosion resistance. It is used in products requiring these properties, such as in kitchens. Common ferritic stainless steel alloys include 430 and 434.
Duplex Stainless Steel
In this type, stainless steel combines both ferritic and austenitic stainless steels. It is less expensive and has high corrosion resistance. It is commonly used underwater in the oil industry. It is also weldable and flexible, which reduces the number of components needed in manufacturing.
Martensitic Stainless Steel
This type resembles ferritic stainless steel but contains a higher carbon content. Due to this feature, it is hard, rust-resistant, durable, and ideal for making pumps and valves. Popular martensitic stainless steel alloys include 431 and 420S45.
Precipitation-Hardening Stainless Steel
This is the strongest type of stainless steel due to the addition of elements like niobium, aluminum, and copper. It has other properties that can be compared to standard austenitic types.
Uses of Stainless Steel
Due to its distinctive properties, stainless steel is primarily used for its rust and stain resistance. Some applications include:
Kitchenware
One of the most common uses of stainless steel is in kitchen tools such as cutlery and cooking utensils. It is used in cookware because it does not easily damage and performs excellently in terms of both durability and aesthetics.
Medical Equipment
Due to its rust and stain resistance, stainless steel is used to manufacture medical tools. It is antibacterial and does not react with cleaning solutions, making it easy to clean and sterilize.
Food Processing and Handling
Stainless steel is used in products involved in food processing and handling because it does not affect the properties of the food. It is corrosion-resistant and easy to clean.
Automotive Industry
Given that stainless steel resists rust, it is an important material in many automobiles. It is used in the production of trains, cars, and some aircraft components.
