Get to know what stainless steel is
Definition of Stainless Steel
What is stainless steel? Stainless steel is a type of alloy metal that is renowned for its resistance to corrosion and tarnishing and is therefore often referred to as stainless steel. This metal contains at least 10.5% chromium, which forms a chromium oxide layer on its surface. This layer prevents further corrosion by protecting the metal underneath. Due to its durability and strength, stainless steel is widely used in various industries, ranging from kitchen appliances to building construction.

Composition of Stainless Steel
The main composition of stainless steel is iron, chromium, nickel, and molybdenum. The following are some of the key components and their functions:
- Iron (Fe): The basic element in stainless steel.
- Chromium (Cr): Provides resistance to corrosion and oxidation.
- Nickel (Ni): Adds toughness and corrosion resistance.
- Molybdenum (Mo): Improves corrosion resistance in harsher environments, such as seawater.
Types of Stainless Steels
There are several types of stainless steel that are categorized based on their crystal structure and chemical composition, including:
1. Austenitic Stainless Steel
High in nickel and chromium. This type is most common and is known for its resistance to corrosion as well as its ability to maintain strength at high temperatures.
2. Ferritic Stainless Steel
Contains more chromium and less nickel than austenitic. It is less resistant to corrosion but more resistant to cracking.
3. Martensitic Stainless Steel
Contains less chromium and has high carbon. It is hard and strong, but less resistant to corrosion.
4. Duplex Stainless Steel
The combination of austenitic and ferritic structures, provides good strength and corrosion resistance.
5. Precipitation-Hardening Stainless Steel
Known for the high strength achieved through the precipitation hardening process.
