Nowadays, the applications of stainless steel in industry and production are gradually becoming popular. With many outstanding advantages, stainless steel can be considered the leading material in production. Join Hoa Giang to learn about the applications of stainless steel in practice through the following article.
General features of Stainless Steel
Concept
Stainless steel is also known as steel alloy. The main component of stainless steel is iron, and contains large amounts of elements such as: Chromium, Carbon, Nickel, Manganese, … and some other elements.
Stainless steel contains at least 10.5% Chromium, which is the element that helps stainless steel increase its corrosion resistance. The remaining elements also give stainless steel outstanding advantages such as: non-magnetic, flexible, easy to bend and easy to process,…
In addition, some types of stainless steel also have different adjusted content of substances in the composition, which will have different properties, durability, and hardness. These types of stainless steel will be named to distinguish them, based on their composition and characteristics. We will learn about them in the Popular types of stainless steel on the market.
Highlight features of Stainless Steel
The chemical composition of stainless steel has created many outstanding properties such as:
- Good corrosion resistance: Thanks to the large amount of chromium contained in the composition, creating a protective layer, preventing direct contact with water, air, … making stainless steel difficult to oxidize and corrode over time.
- High durability: Stainless steel has high hardness, can withstand the impact of pressure and all environments, even in harsh environments (high temperature, acid, alkali, …) Besides, stainless steel is not easily deformed when the temperature changes.
- Easy to clean: With a smooth surface, stainless steel is easy to clean and sanitize without taking much time and effort.
- Safe in production: Stainless steel does not react chemically with any ingredients in food products, beverages, pharmaceuticals, … ensuring safety during the production process.
- Aesthetic: Stainless steel has a shiny surface and is easy to process in many different styles. Therefore, they are widely used in civil life and industrial production.
- Saving maintenance costs: Thanks to its long life and high durability, stainless steel helps save maintenance and replacement costs. Stainless steel also has recycling value, contributing to environmental protection.
Thanks to the above characteristics, the applications of stainless steel are becoming increasingly important in life as well as in industrial production.
Popular types of stainless steel on the market
Based on chemical composition and physical properties, stainless steel is divided into many different types. Below, Hoa Giang will summarize the popular types of stainless steel, widely used in today’s life.
Stainless steel 304
This is the most popular type of stainless steel on the market. Stainless steel 304 is known for its good corrosion resistance and easy processing. The chemical composition of SUS 304 includes:
- About 18 – 20% Chromium
- From 8 – 10.5% Nickel
- A small amount of Manganese, Silicon,…
Stainless steel 304 can withstand corrosion from acids, alkalis and cleaning chemicals, household chemicals,… This type of stainless steel is easy to weld and does not require heat treatment after welding, easy to process, and can be thinned without losing mechanical properties.
The applications of stainless steel 304 are widely used in many areas of life: food tanks, kitchen equipment, medical instruments, construction materials, interior and exterior decoration, and some other household items,…
Stainless Steel 316
Stainless Steel 316 with added Molybdenum increases corrosion resistance, especially in seawater (salt) and strong chemical environments. The main components of this type of stainless steel include:
- About 16 – 18% Chromium
- From 10 – 14% Nickel
- 2 – 3% Molybdenum
- Other elements: Manganese, Silicon,…
Stainless Steel 316 has high durability and excellent corrosion resistance. The applications of stainless steel 316 are the first choice in harsh working environments, strong chemicals, and marine environments. They also have good weldability and machining, but attention should be paid to the welding process because it can affect the corrosion resistance of this type of stainless steel.
Stainless Steel 316 is used to manufacture medical equipment, implants, surgical instruments; equipment for the marine industry, equipment in food and chemical production,…
Stainless Steel 201
Stainless Steel 201 is mainly composed of iron and contains a large amount of Manganese instead of Nickel. This helps reduce production costs, but their corrosion resistance will also decrease. This type of stainless steel is not as magnetic and has a lower corrosion resistance than the above two types, so it is only suitable for making common household items. Not suitable for use in high temperature environments and strong chemicals.
Stainless Steel 430
Stainless Steel 430 is a type of stainless steel that contains a larger amount of Chromium, about 16 – 18%, and does not contain Nickel. This also helps reduce production costs, but also affects the corrosion resistance of this type of stainless steel. Stainless Steel 430 is easy to process, but its ductility and weldability are not as good as stainless steel 304 and 316. Stainless Steel 430 belongs to the ferritic steel line, is magnetic and is often used in the production of automotive parts.
Applications of Stainless Steel in Real life
Thanks to its outstanding properties, stainless steel is widely used in most areas of life. Below are some applications of stainless steel in specific areas.
Applications of stainless steel in civil life
As daily life is increasingly improved, the applications of stainless steel will gradually replace the application of conventional steel materials. Thanks to its durability, aesthetics, and rust resistance, stainless steel is widely chosen in many areas of life such as:
In Architecture and construction
This is one of the common applications of this material. Stainless steel can be used for exterior cladding, door frames, signs, column cladding of large buildings, etc. Thanks to the advantages of being easy to weld, easy to clean, hygienic, and does not require regular maintenance; stainless steel is also used for interior decoration in hotels, restaurants, shopping centers, etc. The shiny feature of stainless steel helps the space become brighter, bringing natural light into the house, reducing energy consumption, and saving effectively.
In addition, thanks to its heat resistance and high fire resistance, stainless steel is also used in fire protection systems of buildings, apartments, etc. to ensure fire safety.
In Medical
With its rust-free and antibacterial properties, stainless steel is used to make medical equipment and supplies such as: surgical instruments, operating tables, dental instruments, steam sterilizers, MRI scanners, etc. In addition, with its inert properties, it is also used as medical nails, used for fixing in surgery or fixing broken bones/joints.
In Household appliances
With the characteristics of no rust and high durability, stainless steel is commonly used to make household appliances such as: kitchen accessories, sinks, water tanks, ovens, kitchen utensils, deodorizers, sanitary equipment, etc. In addition, they are also used as parts of various types of equipment and machinery such as: washing machine housings, washing machine drums, dishwashers, refrigerators, etc.
