Nitronic 60 vs XM-19- Wha’s the Difference?

Stainless steel alloys are widely used in various industries such as aerospace, marine, and chemical processing because of their strength, durability, and resistance to corrosion. Among the popular stainless-steel alloys used today are Nitronic 60 and XM-19. While both alloys have similar chemical compositions, there are distinct differences in their properties and applications. In this blog post, we will explore the differences between Nitronic 60 and XM-19 and help you understand which stainless-steel alloy fits your needs.

What is Nitronic 60?

Nitronic 60 is austenitic stainless steel commonly used in applications that require high strength and moderate corrosion resistance. It has a balanced combination of nickel, chromium, and manganese, allowing 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 XM-19?

XM-19 is a precipitation-hardened martensitic stainless steel containing 20% chromium, 12% nickel, and 3.5% molybdenum. It offers high strength and has superior corrosion resistance compared to other types of stainless steel. This makes XM-19 ideal for applications in harsh environments such as petrochemical plants or offshore oil rigs. Its nonmagnetic properties also make it popular among medical device manufacturers.

Difference Between Nitronic 60 and XM-19

Chemical Composition

Both Nitronic 60 and XM-19 are austenitic stainless steels with high nitrogen, chromium, and molybdenum levels. However, Nitronic 60 has higher levels of manganese (7-9%) and silicon (3-4%) than XM-19. This composition gives Nitronic 60 superior wear resistance, corrosion resistance, and higher strength at higher temperatures. XM-19, on the other hand, has higher levels of nickel and nitrogen, giving it better corrosion resistance in chloride environments.

Mechanical Properties

Nitronic 60 has excellent mechanical properties and is known for its high strength, toughness, and fatigue resistance. It is also highly ductile, meaning it can be formed into different shapes and sizes without cracking. XM-19, while still considered a high-strength alloy, has lower tensile strength, yield strength, and modulus of elasticity than Nitronic 60. However, it has better elongation and impact strength, making it ideal for applications that require superior toughness.

Corrosion Resistance

Both Nitronic 60 and XM-19 have excellent corrosion resistance but in different environments. Nitronic 60 is highly resistant to pitting and crevice corrosion in acidic and alkaline environments and in high-temperature and high-pressure conditions. XM-19, on the other hand, has superior resistance to stress corrosion cracking and intergranular corrosion in chloride environments such as seawater and brine solutions.


Nitronic 60 and XM-19 are both versatile alloys used in various industries. Nitronic 60 is commonly used in the aerospace, marine, and chemical processing industries for fasteners, valve stems, shafts, and pump components requiring high strength, wear, and corrosion resistance. XM-19, on the other hand, is widely used in the petroleum and chemical processing industries for applications that involve exposure to chloride environments, such as piping systems, heat exchangers, and pressure vessels.


The cost of Nitronic 60 and XM-19 varies depending on the size and quantity of the materials needed, supplier, and location. However, Nitronic 60 is generally more expensive than XM-19 because of its superior mechanical properties and corrosion resistance. For more information visit MarketsMartb2b


In conclusion, Nitronic 60 and XM-19 are high-performance stainless steel alloys with unique properties and applications. Nitronic 60 is known for its high strength, wear resistance, and corrosion resistance in high-temperature and high-pressure conditions, while XM-19 has superior toughness and corrosion resistance in chloride environments. When choosing between the two alloys, it is essential to consider the specific application and environment to determine which alloy will perform best. Ultimately, the best choice depends on the specific needs of your project, and consulting with a metal supplier or manufacturer can help you make an informed decision.
