Comparison of similarities and differences between stainless steel 304 and stainless steel 201
In the debate between Inox 304 and Inox 201, these two types of materials have similarities and differences in terms of chemical composition, durability, shine and smoothness, corrosion resistance, susceptibility to magnetism, and cost. Here are some comparisons between them.
Comparison of Chemical Composition between Inox 304 and Inox 201
Inox 304 and Inox 201 are two popular stainless steels in the market. Here is a comparison of their chemical composition:
Comparison of Chemical Composition of Inox 304 and Inox 201
| Chemical Composition of Inox 304 | Chemical Composition of Inox 201 | |
| Chromium (Cr) | 18-20% | 16-18% |
| Nickel (Ni) | 8-10.5% | 3.5-5.5% |
| Manganese (Mn) | 2% maximum | 5.5-7.5% |
| Silicon (Si) | 1% maximum | 1% maximum |
| Sulfur (S) | 0.03% maximum | 0.03% maximum |
| Phosphorus (P) | 0.045% maximum | 0.06% maximum |
| Carbon (C) | 0.08% maximum | 0.15% maximum |
Because stainless steel 304 has a higher nickel content and lower manganese content compared to stainless steel 201, stainless steel 304 has better durability, corrosion resistance, and heat resistance than stainless steel 201. However, stainless steel 201 has a higher hardness than stainless steel 304, so it is used in applications that require hardness but do not require high corrosion resistance and heat resistance.
Comparison of Durability between Stainless Steel 304 and Stainless Steel 201
The durability of stainless steel 304 and stainless steel 201 depends on various factors, including the environment of use, intensity, and duration of use. However, we can still make a general comparison of the durability of these two types of stainless steel as follows:
| Stainless Steel 304 | Stainless Steel 201 | |
| Durability |
Stainless Steel 304 has higher durability than stainless steel 201 because it contains more chromium and nickel, which enhances the corrosion resistance and heat resistance of the material. Therefore, stainless steel 304 is often used in applications that require higher durability, such as in the production of medical equipment, food processing equipment, water and oil pipelines. |
Stainless Steel 201 has lower durability compared to stainless steel 304. Therefore, it is often used in applications that do not require high durability, such as windows and door frames. |
In summary, stainless steel 304 has higher durability than stainless steel 201 due to its higher chromium and nickel content. However, the durability of both types of stainless steel depends on various factors and needs to be carefully considered before use.
Comparison of Shine and Smoothness between Stainless Steel 304 and Stainless Steel 201
| Brightness | Smoothness |
|
Inox 304 usually has a higher brightness than Inox 201 due to its higher content of Chromium and Nickel, which enhances the surface’s shine. However, the brightness of Inox 201 is also quite good and is often used in applications that require high aesthetic appeal, such as interior decoration. |
Inox 304 has a higher smoothness on the surface compared to Inox 201 due to a more complex production process, including refining and bleaching steps to create a smoother and more even surface. However, the smoothness of Inox 201 is also quite good and meets the requirements for applications in interior decoration. |
In summary, Inox 304 has a higher brightness and smoothness on the surface compared to Inox 201. However, both types of stainless steel have good brightness and smoothness and can meet the requirements for applications in interior decoration and the production of high aesthetic products.
Comparison of Rust and Corrosion Resistance between Inox 304 and Inox 201
In terms of rust and corrosion resistance, Inox 304 and Inox 201 have the following differences:
| Rust Resistance | Corrosion Resistance |
| Inox 304 contains a higher amount of Chromium and Nickel compared to Inox 201, resulting in better rust resistance and corrosion resistance. This makes Inox 304 commonly used in applications that require high rust resistance, such as manufacturing medical equipment, food processing equipment, water and oil pipelines. | Inox 201 has a different chemical composition than Inox 304, containing small amounts of other alloys like copper and manganese, which give it better corrosion resistance and strength than Inox 304 in weak acid environments. However, Inox 201 can be corroded when exposed to stronger chemicals and seawater. |
Comparison of Electromagnetic Susceptibility between Inox 304 and Inox 201
Electromagnetic susceptibility refers to the ability of a material to be affected by surrounding electromagnetic fields. When placed in an environment with electromagnetic fields, materials with low electromagnetic susceptibility can be impacted and may exhibit phenomena such as electrochemical corrosion or fracture. Inox 304 and Inox 201 have some differences in electromagnetic susceptibility as follows:
| Inox 304 | Inox 201 | |
| Electromagnetic Susceptibility | Inox 304 has better resistance to electromagnetic susceptibility compared to Inox 201 due to its higher content of chromium and nickel. Chromium and nickel have better oxidation resistance, enabling Inox 304 to withstand stronger electromagnetic fields. | Inox 201 has poorer resistance to electromagnetic susceptibility compared to Inox 304 due to its lower content of chromium and nickel. This makes Inox 201 more vulnerable to the surrounding electromagnetic fields, especially in electrochemical corrosion environments. |
In summary, Inox 304 has better resistance to electromagnetic susceptibility than Inox 201 due to its higher content of chromium and nickel. However, both types of stainless steel can be affected by strong electromagnetic fields and require protection in environments with strong electromagnetic fields.
Comparison of Cost between Stainless Steel 304 and Stainless Steel 201
The cost of stainless steel 304 and stainless steel 201 can vary depending on several factors such as the market, supply source, production costs, etc. However, generally speaking, stainless steel 304 is more expensive than stainless steel 201. This is because stainless steel 304 has a more complex chemical composition, including more chromium and nickel, and requires a more stringent production process.
On the other hand, stainless steel 201 has a simpler chemical composition and is easier to produce, so its cost is usually lower than stainless steel 304. However, if you intend to use it in applications that require higher performance or in high humidity environments, stainless steel 304 would be a better choice, despite its higher cost.
Therefore, the choice between stainless steel 304 and stainless steel 201 is not solely based on cost but also needs to consider other factors such as functionality, application, and usage environment in order to select the most suitable stainless steel type.
