FAQS
The primary advantage of 16mo3 en 10216 2 is its molybdenum content, which provides significantly higher creep strength. While standard carbon steel loses structural integrity and begins to deform at temperatures above 400°C, 16Mo3 is specifically formulated to maintain its mechanical properties at higher temperatures, ensuring that boiler tubes do not bulge or rupture under extreme pressure.
It is not inherently "difficult," but it does require strict adherence to welding procedures. Because it is a low-alloy steel, it is susceptible to cracking if cooled too quickly. To ensure a high-quality joint, operators must perform pre-heating and a Post-Weld Heat Treatment (PWHT). When these steps are followed, the weld strength is comparable to the parent metal, making it very reliable for field installation.
Verification should be done through a Mill Test Certificate (MTC) according to EN 10204. Look for a Type 3.1 or 3.2 certificate, which provides the actual chemical analysis and mechanical test results.
