Stainless Steel 201 vs 430 – What’s the Difference

Stainless Steel 201 vs 430

Stainless steel has become an incredibly popular material for various applications, including appliances, cookware, and even jewellery. Two commonly used stainless steel grades are 201 and 430, but what’s the difference between the two? In this blog post, we’ll explore the differences between the two grades and help you decide which one is best for your needs.

Difference Between Stainless Steel 201 and 430


Stainless steel 201 and 430 differ in their composition. Stainless steel 201 contains 16%-18% chromium, 3.5%-5.5% nickel, and 0.8%-1.2% manganese. This grade has low nickel content and is considered a cost-effective option. In contrast, stainless steel 430 contains 16%-18% chromium and 0.12% carbon but no nickel. This makes 430 more affordable than 201 but also less durable.

Corrosion resistance:

201 and 430 are corrosion-resistant, but 201 is more corrosion-resistant than 430. This is due to the higher nickel content in 201, which provides greater resistance to corrosion caused by acids, humidity, and salt. If you’re looking for stainless steel that’s more immune to corrosion, 201 is a better choice.

Heat resistance:

Heat resistance is another factor that differentiates stainless steel 201 and 430. Stainless steel 201 offers better heat resistance than 430. It can withstand temperatures up to 1500 degrees Fahrenheit, whereas 430 can only handle temperatures up to 1100 degrees Fahrenheit. If you’re looking for a stainless steel used in high-heat environments, 201 is the better choice.


The differences in composition, corrosion resistance, and heat resistance affect the applications of stainless steel 201 and 430. Stainless steel 201 is commonly used in appliances such as refrigerators, dishwashers, and ovens, as well as for cookware and kitchen equipment. Stainless steel 430 is often used in automotive trim and moulding, roofing, and kitchen sinks. If you need help determining which grade is best for your application, consult a reputable stainless steel supplier.


Finally, cost is a significant factor when deciding between stainless steel 201 and 430. Stainless steel 430 is generally less expensive than 201, but 201 is considered a more premium grade due to its higher nickel content. If cost is your primary concern, 430 might be a more practical choice. However, if you’re willing to invest more in quality, opting for 201 could be more beneficial in the long run.


In conclusion, the stainless steel 201 and 430 differences come from composition, corrosion resistance, heat resistance, applications, and cost. Both grades are popular options for various applications, but they have their strengths and weaknesses. If you’re looking for a more affordable option, 430 is the way to go. If you prioritize durability and resistance to corrosion and heat, 201 would be a better choice. Either way, it’s always best to consult a professional stainless steel supplier to determine which grade suits your needs and requirements.
