differences between stainless steel and regular steel
Stainless steel and regular steel, also known as carbon steel, are two different types of alloys that have unique properties and characteristics. The main difference between them lies in their composition and the way they are manufactured.
Composition
The difference in composition between stainless steel and regular steel lies in the type and content of alloying elements they contain.
Stainless steel is an alloy steel with high corrosion resistance and wear resistance, usually consisting of iron, chromium, nickel, and small amounts of carbon, manganese, and silicon. Among them, the content of chromium reaches more than 10.5%, which can form a dense oxide layer to protect the steel surface from corrosion. The nickel content contributes to the strength and plasticity of stainless steel and improves its corrosion and heat resistance.
When it comes to the composition of regular steel, it is mainly composed of carbon and iron. The carbon content of steel usually ranges from 0.2% to 2.1%, and the higher the carbon content, the harder the steel will be. In addition, the steel may contain other elements such as manganese, silicon, phosphorus, and sulfur to improve the mechanical properties of the steel. The content and proportions of these elements can be fine-tuned as needed to produce steels with specific properties.
In addition, stainless steel can also add other elements such as molybdenum, cobalt, titanium, etc., according to specific applications. These elements can further improve the corrosion resistance, strength and high temperature resistance of stainless steel and other characteristics. In short, the difference in composition between stainless steel and regular steel determines the differences in their physical properties, chemical properties, mechanical properties and uses.
Manufacturing
The differences in the manufacturing processes of stainless steel and regular steel are significant. Steel is produced by heating and melting ore in a blast furnace and mixing it with other materials (such as iron ore and coke). This process is known as basic steelmaking.
However, the manufacture of stainless steel requires the addition of other elements, such as chromium, nickel, and molybdenum. These elements improve the properties of stainless steel such as corrosion resistance, heat resistance, and strength. Stainless steel is generally manufactured by placing raw materials (e.g., steel, chromium, nickel, molybdenum, etc.) into an electric arc furnace, where they are heated to high temperatures and melted. By adjusting the type and proportion of added materials, different grades, and types of stainless steel can be obtained.
Regular Steel
Steelmaking
Steelmaking is the process of melting, reducing, and refining iron ore and other raw materials at high temperatures to obtain steel materials. This process usually takes place in a blast furnace or electric arc furnace and can vary depending on the raw material.
Continuous casting
The process of casting the refined steel into long bars or plates. This process can be divided into several steps such as billet casting, crystallizer, billet shell, and cooling.
Hot or Cold Rolling
The process of forming the billet at high or room temperature through several processes such as rolling and drawing. This process produces steel of different sizes, shapes, and surface finishes.
Surface treatment
The steel is surface treated through processes such as pickling, rust removal and spraying to make the steel surface flatter, smoother, rust-proof, etc.
processing
The steel is processed by shearing, cutting, stamping, drilling, welding, and other processing according to the need to adapt to different use scenarios and needs.
Stainless Steel
Smelting
Stainless steel is made by alloying iron, chromium, nickel, and other elements. In the smelting process, iron ore is first smelted into pig iron, and then pig iron and other alloying elements (such as chromium, nickel, and molybdenum) are added to the furnace to make stainless steel through a high-temperature reaction and cooling process.
Rolling
Once smelting is complete, stainless steel is usually pressed into sheets or coils. These steels usually need to be rolled at high temperatures to change their shape and thickness. This process usually involves the use of a series of rolls and equipment to press the steel to the desired size and thickness.
Processing
The final step is to process the stainless steel into the desired shape, such as pipe, bar, plate, etc. Processing typically involves the use of a range of machining tools and equipment such as drill presses, punches, cutters and benders to cut, punch and bend the stainless steel material into the desired shape and size.
Overall, understanding the key differences between stainless steel and regular steel is crucial in selecting the appropriate material for your project. If you are in need of high-quality stainless steel, be sure to reach out to reputable stainless steel suppliers who can provide you with the best options for your specific needs.
differences in properties
The differences in composition between stainless steel and regular steel determine their physical properties, chemical properties, mechanical properties and uses.
corrosion resistance
Stainless steel has higher corrosion resistance compared to regular steel. This is determined by the chemical composition of stainless steel. Stainless steel contains at least 10.5% chromium, while ordinary steel has a higher iron content. Chromium forms a dense layer of chromium oxide in stainless steel, called a passivation layer, which prevents oxygen, water, and other corrosive substances from attacking the metal surface.
The passivation layer gives stainless steel excellent corrosion resistance to common forms of corrosion, such as water corrosion, oxidation corrosion, and acid corrosion. This allows stainless steel to maintain its appearance and performance stability in wet environments, chemical exposure, and high temperature conditions.
In addition, other alloying elements added to stainless steel, such as nickel, molybdenum and titanium, can further improve its corrosion resistance. These alloying elements enhance the oxidation resistance, acid resistance and alkaline resistance of stainless steel, making it suitable for more severe environments.
All in all, stainless steel has higher corrosion resistance than ordinary steel, which makes it the material of choice in many fields, including construction, chemicals, food processing, medical equipment, and marine engineering.
elasticity and ductility
Stainless steel has better elasticity and ductility compared to regular steel. This is due to the crystal structure and composition of stainless steel.
The crystal structure of stainless steel has a face-centered cubic (FCC) structure, which makes stainless steel has good elastic properties. It is able to recover its original shape after being stressed and is less likely to deform or break. This elasticity allows stainless steel to withstand high stresses and heavy loads in a variety of applications without losing its shape and structural integrity.
In addition, stainless steel has good ductility, also known as plasticity. It is able to undergo plastic deformation under stress without fracture. The high ductility of stainless steel allows it to be cold-worked and hot-worked into a variety of shapes such as plates, tubes, and bars to meet different needs.
This advantage of elasticity and ductility makes stainless steel widely used in many fields. For example, in building and structural engineering, stainless steel is able to withstand deformation and vibration without breaking and is therefore widely used in structural support for bridges, building frames, and high-rise buildings. In addition, in the automotive, aerospace, manufacturing, and electronics fields, stainless steel is also an important material choice because of its superior elasticity and ductility.
Overall, stainless steel has better elasticity and ductility than ordinary steel, making it a reliable and versatile material for a variety of engineering and manufacturing applications.
heat resistance and wear resistance
First, stainless steel has good heat resistance in high-temperature environments. This is determined by the alloy composition and crystal structure of stainless steel. Among them, high-alloyed stainless steels (such as 316 and 310, etc.) have higher heat resistance and are able to maintain structural stability and strength at high temperatures. This makes stainless steel widely used in applications such as high-temperature processes, heat treatment, and combustion equipment.
Second, stainless steel also has better wear resistance. The wear resistance of stainless steel depends mainly on its hardness and surface finish. Alloying elements added to stainless steel, such as chromium, molybdenum and titanium, can improve its hardness and wear resistance. In addition, the wear resistance of stainless steel can be further enhanced by surface treatment methods such as polishing, sandblasting, and nitriding. This allows stainless steel to excel in applications where resistance to wear and corrosion is required, such as mechanical parts in manufacturing, food processing equipment, and chemical installations.
As a result, the high heat and wear resistance of stainless steel has led to its widespread use in many fields. Whether in high-temperature environments or where resistance to wear and tear is required, stainless steel provides long-lasting durability and reliable performance. This makes stainless steel an ideal material choice for a variety of engineering and manufacturing needs.
