Nitronic 30 vs SS 304 – What’s the Difference?

Stainless steel is an essential component in numerous industries, and it is an alloy made up of different elements, such as chromium, nickel, molybdenum, and nitrogen, to name a few. Different stainless steel grades are available in the market, including SS 304 and Nitronic 30, that are widely used. But what are the differences between Nitronic 30 and SS 304, and which should you use? This blog post will help you understand these two stainless steel grades and make an informed decision.

Difference between Nitronic 30 vs SS 304


The composition of Nitronic 30 is unique compared to SS 304. Nitronic 30 contains 20-23% chromium, 11-13% nickel, and 1.5-3% manganese, with nitrogen addition. On the other hand, SS 304 contains 18-20% chromium and 8-10.5% nickel. Nitrogen is not normally included in SS 304, unlike Nitronic 30.

Corrosion Resistance:

Nitronic 30 has better corrosion resistance than SS 304, especially in environments with high chloride levels. Its higher nickel and manganese content makes it resistant to pitting and crevice corrosion. SS 304, on the other hand, is vulnerable to rusting and corrosion when exposed to acidic, alkaline, or chloride-rich environments.


Nitronic 30 is a high-strength, low-elastic modulus material. It’s higher yield and tensile strength compared to SS 304 make it suitable for high-stress applications. However, SS 304 is a relatively soft material, which makes it easier to form, weld, and fabricate.


The cost of Nitronic 30 is generally higher than SS 304. Nitronic 30 is more expensive due to its unique composition and resistance properties, making it an ideal choice for high-performance applications where resistance to corrosion, wear, and high strength are critical. On the other hand, SS 304 is more economical, with suitable corrosion resistance and good formability.


Nitronic 30 is a popular stainless steel grade used in the nuclear, aerospace, oil, and gas industries due to its high strength and excellent corrosion resistance. It is also suitable for high-temperature environments and can withstand temperatures up to 600°F. SS 304 is commonly used in the food, chemical, and pharmaceutical industries, requiring a lower material cost and good corrosion resistance. For more information visit MarketsMartb2b


Choosing between Nitronic 30 and SS 304 will depend on the specific application and the environment that it will be exposed to. The composition, corrosion resistance, strength, cost, and applications are all factors that should be considered before making a choice. Nitronic 30 is ideal for high-performance applications where strength, corrosion resistance, and pitting resistance are critical factors, while SS 304 is suitable for applications where cost-effectiveness, formability, and good corrosion resistance are essential requirements. Always seek advice from experts and professionals to ensure you select the best stainless steel grade for your task.
