304 vs 321 Stainless Steel

When it comes to choosing the right stainless steel for your project, understanding the differences between 304 and 321 stainless steel is crucial. Both types are austenitic stainless steels, but they have distinct properties that make them suitable for different applications.

304 Stainless Steel is one of the most commonly used stainless steels due to its excellent corrosion resistance, formability, and weldability. It contains 18% chromium and 8% nickel, making it highly versatile for a wide range of applications, from kitchen equipment to chemical processing.

321 Stainless Steel, on the other hand, is stabilized with titanium, which enhances its resistance to intergranular corrosion after exposure to high temperatures. This makes 321 stainless steel plate ideal for applications involving continuous or intermittent heating up to 900°C, such as in aerospace and thermal processing industries.

At Normandy Steel Industry Co., Ltd., we offer both 304 and 321 stainless steel, ensuring you get the best material for your specific needs.

SS 321 vs SS 304 Price

When comparing the prices of ss 321 vs ss 304, it’s important to consider the specific requirements of your project. Generally, 321 stainless steel is more expensive than 304 stainless steel due to the addition of titanium, which enhances its high-temperature performance and corrosion resistance.

However, the higher cost of 321 stainless steel can be justified by its superior performance in high-temperature environments. For applications that do not require such high-temperature resistance, 304 stainless steel remains a cost-effective and reliable choice.

Normandy Steel Industry Co., Ltd. offers competitive pricing on both 304 and 321 stainless steel, ensuring you get the best value for your investment. Our expert team can help you determine which type of stainless steel is most suitable for your project, balancing performance and cost.

SS 321 vs SS 316

When comparing ss 321 vs ss 316, both types offer excellent corrosion resistance, but they are optimized for different conditions.

316 stainless steel sheet metal contains molybdenum, which significantly enhances its resistance to pitting and crevice corrosion in chloride environments. This makes 316 stainless steel ideal for marine applications, chemical processing, and medical devices.

321 Stainless Steel, as mentioned earlier, is stabilized with titanium, making it more suitable for high-temperature applications. While 316 stainless steel performs exceptionally well in corrosive environments, 321 stainless steel excels in high-temperature stability and resistance to intergranular corrosion.

At Normandy Steel Industry Co., Ltd., we provide a wide range of stainless steel products, including 304, 316, and 321 grades. Our commitment to quality and customer satisfaction ensures that you receive the best materials for your specific needs. Whether you require the high-temperature stability of 321 stainless steel or the superior corrosion resistance of 316 stainless steel, we have the expertise and inventory to meet your requirements.
