In the application of industrial fast doors, stainless steel is widely used in food, pharmaceutical, electronic, and cleanroom industries due to its advantages of corrosion resistance, high strength and beautiful appearance. The primary materials of stainless steel rapid doors include 304 stainless steel and 201 stainless steel, but they are significantly different in performance, durability, and applicable scenarios.
So, stainless steel fast door 304 material vs 201 material, which one is more suitable for your industry needs? In this article, we will make a detailed comparison of the corrosion resistance, mechanical properties, service life, and other aspects, and help you choose a more suitable stainless steel industrial door program.
304 Stainless Steel vs 201 Stainless Steel Rapid Door Main Differences
Comparison of material composition
✅ 304 stainless steel fast door
Nickel (Ni) content: 8%~10%, with good corrosion resistance and rust resistance.
Chromium (Cr) content: 18%, improves oxidation resistance, suitable for humid and corrosive environments.
✅ 201 stainless steel industrial door
Lower nickel content (about 1%), the main component is manganese (Mn), weaker corrosion resistance.
Suitable for dry and low corrosive environments, such as general warehouses and commercial stores.
Corrosion resistance comparison
304 stainless steel fast door: strong rust resistance, suitable for food processing plant, clean room, seaport storage and other high humidity environment.
201 stainless steel industrial door: easy to rust, not suitable for humidity, chemical storage, high salt spray environment.
Mechanical strength and service life
304 stainless steel material has high strength, better impact resistance, and a service life of more than 10 years.
201 stainless steel hardness is higher, but brittle, shorter service life, easy to corrode for a long time.
304 Stainless Steel vs 201 Stainless Steel Rapid Door, How to choose?
Scenarios for choosing 304 stainless steel rapid door
✅ Food processing workshop, pharmaceutical factory, medical clean room, meets the hygiene standard, strong corrosion resistance.
✅ Marine port warehouses, chemical plants, can resist high humidity and chemical erosion.
✅ Long-term high-frequency use of industrial environments, such as logistics centers, cold chain warehouses, not easy to rust, low maintenance costs.
Scenarios for choosing 201 stainless steel industrial doors
✅ General warehouses, garages, commercial stores that are not exposed to humidity or corrosive environments.
✅ Stainless steel door with limited budget but need some strength, such as supermarket back warehouse, production line isolation door.
Combining anti-corrosion durable technology to extend the service life of stainless steel speed doors
Currently, anti-corrosion durable industrial doors (keywords: anti-corrosion durable industrial doors) are also offered in the market to enhance the corrosion resistance of 201 and 304 stainless steel using surface plating, electrolytic polishing, and nano-coating. Example:
In high humidity environments (e.g. cold storage, pharmaceutical workshops), electrolytic polishing 304 stainless steel is used to further enhance oxidation resistance.
In general industrial environments, 201 stainless steel with surface sprayed anti-rust coating can be selected to extend the service life.
In seaport terminals and chemical storage areas, it is recommended to use 316 stainless steel fast doors with stronger corrosion resistance.
Conclusion: 304 stainless steel vs 201 stainless steel, which is more worth investing?
If you need a high-strength, corrosion-resistant, long-term use of stainless steel speed door, choose 304 stainless steel, safe and reliable, long service life.
If your use environment is drier and does not require high corrosion resistance, 201 stainless steel is a more cost-effective choice.
Anti-corrosion and durable industrial doors combine 304/201 stainless steel with surface treatment technology to further enhance durability.
