The answer: Choosing 201 stainless steel or 304 stainless steel door handles mainly depends on the usage environment and budget. 201 stainless steel door handles are suitable for indoor, dry environments and for price-sensitive consumers. While 304 stainless steel door handles are suitable for a variety of environments, especially wet or highly corrosive environments, and their durability and corrosion resistance provide a higher long-term value despite the higher price.
1. Material
SS201：
| Chromium | nickel | Carbon | Silicon | Manganese | Phosphorus |
|---|---|---|---|---|---|
| 16.00-18.00 | 3.50-5.50 | ≤0.15 | ≤0.75 | 5.50-7.50 | ≤0.06 |
SS304：
| Chromium | nickel | Carbon | Silicon | Manganese | Phosphorus |
|---|---|---|---|---|---|
| ≥18.00 | ≥8.00 | ≤0.08 | ≤0.75 | ≤2.00 | ≤0.045 |
2.Corrosion Resistance
- 201 stainless steel is less corrosion-resistant than 304 stainless steel. It can handle indoor environments, but not humid or chemical-rich ones. 201 stainless steel door handles are better for dry, mild environments.
- 304 stainless steel has excellent corrosion resistance. It is able to maintain better stability in harsh environments and does not rust easily. Therefore, 304 stainless steel door handles excel in a variety of environments and are more suitable for outdoor or high humidity environments.
3. Cost and cost-effective
- 201 stainless steel due to the low production cost, it is also relatively inexpensive. For consumers who have a limited budget but need to use stainless steel door handles, 201 stainless steel is a more affordable option.
- 304 stainless steel costs more due to its superior properties. Although the price is higher than 201 stainless steel, its longer service life and better performance make it more cost-effective for long-term use.
4.Durability
In regard to door hardware, there is no notable distinction between 201 and 304 door handles in terms of durability.
