XM19 – an alternative to 1.3964

If you are considering material 1.3964 to meet your requirements for strength and corrosion resistance, you should also take a close look at XM19 (Nitronic® 50). This proven high-performance stainless steel is widely used in Anglo-American and Asian markets and offers not only comparable properties but is also sufficiently capable in many critical applications—while being a more cost-effective alternative.

Why is XM19 an alternative to 1.3964?

1. Higher strength
Compared to 1.3964, XM19 offers comparable strength of at least 690 N/mm² and therefore similar load-bearing capacity.

2. Corrosion resistance
With a PREN value of at least 33, XM19 is just as resistant as 1.3964 in chloride-containing environments (such as seawater).
Thanks to their unique chemical compositions, both materials are also resistant to pitting, stress corrosion cracking, and chemical attack.

3. Proven versatility
1.3964 and XM19 have demonstrated their performance across a wide range of industries and under extreme conditions:

  • Offshore and seawater applications
  • Chemical industry
  • Highly stressed components in aerospace

4. Performance at elevated temperatures
1.3964 also exhibits excellent stability at elevated temperatures. Although XM19 has a slightly lower molybdenum (Mo) content, this is compensated by the addition of vanadium, allowing it to perform well in high-temperature applications.

When should 1.3964 be preferred over XM19?

  • If your application requires a PREN value higher than 33
  • If you are looking for a proven, internationally recognized material within the European market
  • XM19, on the other hand, is the preferred choice in Anglo-American and Asian markets

Conclusion: Investing in performance and safety

Both materials are comparable in terms of their overall property profiles. While XM19 contains slightly lower amounts of nickel (Ni) and molybdenum (Mo) than 1.3964, it can offer advantages in high-temperature applications through the targeted use of vanadium. XM19 is also a more cost-effective alternative to 1.3964.

1.3964 remains the right choice when outstanding strength, corrosion resistance, and durability are critical. Rely on the safety of a proven material that not only meets your requirements but exceeds them.
