What is Stainless Steel?
Iron is one of the softest elements in the universe. Adding up to 2% of carbon to steel, which is now known as steel, gives it incredible strength, hardness, and mechanical properties, all of which are a result of its carbon content. A lot of people use steel due to the abundance of iron and its easy and cheap availability, as well as the fact that steel is also very flexible. However, steel also has a weak spot, which is found in the iron that is used in steel products. Oxidation, or rusting, is a natural process that occurs to metal over time. As a result of oxidation, rust forms.
A chemical reaction occurs when an element is combined with oxygen, resulting in oxidation and corrosion, which takes place on the surface of the metal when oxygen is combined with all elements in nature. The corrosion process forms a very thin layer on the surface of the element, which, once this layer has formed, acts as a protective layer, preventing the material from contact with the air and preventing rust from developing. As a result of this thin layer of protection, the color of the metal hardly changes as the element of iron does. In contrast, the element is not the same as this.
The difference in size between the iron and oxygen atoms causes the iron mineral to fail to form a solid bond at its surface, and this coupled with the penetration of rust into the iron element over time means that iron loses all its strength over time, due to the difference in the size of the iron and oxygen atoms.
Chromium’s small atoms combine very easily and rapidly with oxygen because the atoms are so close to each other. As a result of the combination with oxygen, chromium forms a very thin but very strong layer. This layer is not reacted to by any other reaction. Even if it is damaged, the layer reappears in a few weeks. When chromium is added to steel at a certain rate, the same thing happens: the steel will no longer rust. Stainless steel is obtained by combining more than 10% of chromium with iron and carbon.
Advantages Of Stainless Steel
The ease of manufacturing majority of stainless steels can be formed with cutting, welding, cold and hot forming, and machining techniques, enabling them to be used in most applications.
The majority of stainless steels are strengthened by cold forming, and thanks to the increase in strength, it is possible to reduce the thickness of the material in designs, thereby reducing the weight and price of the part. It has been shown that heat treatments can provide a material with a high degree of strength in certain species.
As stainless steel is available in many different surface qualities, it is possible to maintain the appearance and quality of these surfaces for a long period of time due to their ease of maintenance.
In hospitals, kitchens, food, and pharmaceutical industries, stainless steel material is widely used because of its easy cleaning ability.
When considering the entire lifetime of a produced part, stainless steels are economical material due to its durability and ease of maintenance.
The most common stainless steel grades are 304L and 316L, which are corrosion-resistant materials.
Both 304L and 316L stainless steels are polished or grained the same way, so you can distinguish between them just by looking at them.
How does 304 stainless steel perform? What are its advantages?
304 stainless steel is the most common grade of stainless steel. Due to their corrosion resistance, easy formability, weldability, and mechanical properties, 304-grade stainless steels are one of the most commonly used stainless steel grades in the world. In order to meet their customers’ needs, stainless steel manufacturers are particularly interested in producing 304-grade stainless steel since it is easy to manufacture and has superior properties. As a result of these features, stainless steel manufacturers are able to produce their products more intensively.

A stainless steel of 304 grade has excellent corrosion resistance when used on a daily basis. They are suitable for many applications in a wide range of fields. It is suitable for food production facilities, architectural projects, construction applications, and organic and chemical paint applications. 316-grade stainless steel can be used in very harsh corrosive environments when 304-quality stainless steels are insufficient.
Why is 304 Quality Stainless Steel a good choice?
It is generally found that 304 stainless steel has sufficient mechanical strength, but it is not recommended for applications requiring high yield and rupture strengths. It is possible to harden 304-grade stainless steel by cold rolling, similar to other austenitic steels. After cold rolling, 304-grade stainless steel can become significantly magnetic.
Due to the excellent formability of 304 stainless steel, stainless steel producers are able to provide 304 quality stainless steel to a variety of sectors. This is because it can be used in deep drawing applications without the need for intermediate softening with additional heat treatments. Due to this feature, stainless steel manufacturers are able to produce 304 quality stainless steel, which is commonly used in the production of kitchenware, such as pots and pans, where it is most commonly used in the manufacturing of kitchenware. Besides being easily sliced and converted into other shapes, it can also be used in a variety of other areas as it can easily be cut and shaped into other parts. Furthermore, since it is suitable for welding, all standard welding techniques can be used in the production process.
Stainless Steel 316 and Its Usage Areas:
These steels, which have similar mechanical properties, differ in their nickel and chromium ratios according to their areas of use.
There is an extra corrosion resistance provided by molybdenum in 316 quality stainless sheets of steel as well as resistance to high temperatures. It contains 16% chromium and 10% nickel. Additionally, it contains 2% molybdenum.
304l vs 316l stainless steel properties are that 316L is resistant to sulfuric acid when the concentration is low, while the 304L is resistant to sulfuric acid even when it is in high concentrations, as its structure is designed to be resistant to sulfuric acid. As compared with type 304L stainless steel, type 316L stainless steel has a higher resistance to phosphoric acid.
What are the features of stainless steel 316 L?
There is a difference between 316 L stainless steel and classic 316 grades in that they contain less carbon. The intergranular corrosion resistance of 316 L stainless steel, which is extremely strong against high temperatures, has a wide range of functionalities depending on their application.
According to corrosion resistance, the difference between 304 and 316 stainless steel can be summed up as follows:
As a result, it appeals to a wide range of users:
316 stainless steel is characterized by its low carbon content. 316 L stainless steel, one of its varieties, shows the superior performance when it comes to weldability.

Most commonly used in kitchens and food applications, 304L stainless steel is durable and easy to sanitize.
Stainless steel is also used for auto moldings and trim, wheel covers, hose clamps, exhaust manifolds, storage tanks, pressure vessels, and piping.
304L stainless steel has several disadvantages, including the fact that it is susceptible to corrosion from chloride solutions when used in filling machines. Filling machines should use 316L stainless steel if the product will cause a chemical reaction with it.
316L stainless steel is commonly used in the following applications:
There are two basic types of stainless steel: 316L and 304L. 316L stainless steel is typically used in chemical processing applications, so filing machines dealing with chemicals are usually made from 316L stainless steel.
304 or 316 which is better?
304 vs 316 stainless steel: differences in strength
While both 304 and 316 stainless steel are strong, the 304 vs 316 stainless steel mechanical properties addition of the Molybdenum in the 316 gives it a small advantage in strength over the 304.
Many stainless sheets of steel can be formed using cutting, welding, cold and hot forming, and machining techniques, making them suitable for a wide range of applications.
