S20910 XM-19 1.3964 High Nitrogen Austenitic Stainless Steel Tube
Professional Manufacturer – FUSHUN STEEL TUBE
Steel Grade Introduction and Applications
S20910 (XM-19) Overview
S20910, also known as XM-19, is a high nitrogen austenitic stainless steel specifically designed for hydrogen service applications. This advanced steel grade offers exceptional resistance to hydrogen embrittlement and maintains superior mechanical properties in hydrogen-rich environments. FUSHUN STEEL TUBE specializes in manufacturing high-quality S20910 tubes for critical hydrogen applications worldwide.
1.3964 European Designation
Under the European standard EN 10088, this steel grade is designated as 1.3964. It represents the same high nitrogen austenitic stainless steel composition with enhanced hydrogen resistance capabilities. As a leading manufacturer, FUSHUN STEEL TUBE produces 1.3964 tubes meeting strict European specifications for demanding industrial applications.
HRX19 Brief Introduction
HRX19 is another designation for hydrogen-resistant austenitic stainless steel with similar properties to S20910/XM-19/1.3964 grades.
Primary Applications
These steel grades are extensively used in hydrogen service environments including petrochemical processing, hydrogen production facilities, fuel cell applications, and high-pressure hydrogen storage systems. The excellent resistance to hydrogen embrittlement makes them ideal for critical components in hydrogen infrastructure projects.
Chemical Composition
| Element | Content (%) | Element | Content (%) |
|---|---|---|---|
| Carbon (C) | ≤ 0.08 | Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | 4.00-6.00 | Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 | Chromium (Cr) | 19.00-21.50 |
| Nickel (Ni) | 21.00-23.50 | Molybdenum (Mo) | 1.50-3.00 |
| Nitrogen (N) | 0.20-0.40 | Vanadium (V) | 0.10-0.30 |
The high nitrogen content (0.20-0.40%) is the key characteristic of S20910/XM-19/1.3964, providing enhanced strength and hydrogen resistance. FUSHUN STEEL TUBE ensures precise chemical composition control during manufacturing to meet stringent specifications.
