Nitronic 60 vs 18-8- What’s the Difference?

What is Nitronic 60?

Nitronic 60 is an austenitic stainless steel commonly used in applications that require high strength and moderate corrosion resistance. Its balanced combination of nickel, chromium, and manganese allows it to remain ductile even at low temperatures. It is also resistant to scaling up to 1600°F (850°C) and can be cold-worked without becoming brittle.

What is Nitronic 18-8?

18-8 Nitronic is an austenitic stainless steel alloy. It combines high strength, corrosion resistance, and low temperature impact toughness, making it suitable for many industrial applications. The alloy has good wear and galling resistance and can be used in extreme temperatures from cryogenic to 1800°F (982°C). Moreover, its nitrogen content helps make this alloy more weldable than other 300-series stainless steels

Difference Between Nitronic 60 And 18-8

When choosing a suitable material for a particular job, knowing their characteristics and differences is crucial. Stainless steel alloys are among the most widely used materials in several industries. However, the grade of stainless steel selected largely depends on the specific application and needed properties. This post will explore the differences between Nitronic 60 and 18-8 stainless steel alloys.

Nitronic 60 is a high-grade austenitic stainless steel alloy designed to offer high strength and excellent wear resistance. It includes a blend of 8% to 9% nickel, 16% to 18% chromium, and 7% to 9% manganese. Nitronic 60 has enhanced resistance against stress corrosion cracking, alkali sulfides, and acidic solutions. Additionally, Nitronic 60 can be used in stress applications with temperatures above 300°C. It’s also highly resistant to galling and can be easily machined and cold-worked.

On the other hand, 18-8 stainless steel, also known as 304 stainless steel, consists of 18% chromium and 8% nickel, giving it excellent corrosion resistance properties. Its increased malleability and formability make it a preferred choice for many applications. Furthermore, 18-8 stainless steel is widely utilized in kitchens, food processing facilities, and the medical industry.

Nitronic 60 exhibits superior strength compared to 18-8 stainless steel. Nitronic 60 has a yield strength of 415 MPa, whereas 18-8 stainless steel has a yield strength of 205 MPa. Nitronic 60 has a higher hardness level of up to 260HB, making it suitable for highly abrasive environments. In comparison, 18-8 stainless steel has a hardness level of approximately 140HB. Thus, if a component or equipment is required to be used in a high-stress environment, Nitronic 60 would be the preferred choice. However, if the application involves a less harsh environment, 18-8 stainless steel would suffice.

Nitronic 60’s resistance to cold work hardening is another advantage. As Nitronic 60 is work-hardened, its strength improves. However, Nitronic 60 has resistance to cold work hardening, which means its strength does not increase as much as its 18-8 counterpart when deformed at room temperature. Cold working 18-8 stainless steel at room temperature can significantly enhance its strength and hardness levels. Therefore, if strength improvement through cold work hardening is required, 18-8 stainless steel would be the better option. For more information visit MarketsMartb2b.


Nitronic 60 and 18-8 stainless steel alloys have unique properties, and the grade selected would depend on the application’s specific requirements. Nitronic 60 is more durable, robust and offers higher strength and resistance to corrosion than 18-8 stainless steel. However, when cold-worked, 18-8 stainless steel is more malleable and robust. Understanding the alloys’ differences is essential in selecting the most appropriate material for a job. The choice guarantees overall durability and longevity, making it an intelligent investment in the long run.
