What is 13-8Mo Stainless Steel?
13-8Mo (UNS S13800, W.Nr. 1.4534) is a martensitic precipitation-hardening stainless steel that offers an exceptional combination of high strength, excellent toughness, and superior corrosion resistance. The alloy is double vacuum melted (VIM-VAR: vacuum induction melting followed by vacuum arc remelting) to consistently ensure low gas content, improved homogeneity, and superior cleanliness.
Compared to other ferrous-based materials, 13-8Mo Stainless Steel offers a high level of useful mechanical properties under severe environmental conditions. The alloy is characterised by excellent strength, corrosion resistance, and toughness at both room and elevated temperatures. It provides superior resistance to stress-corrosion cracking and high fracture toughness, making it an ideal choice for critical applications across multiple industries.
Chemical Composition of 13-8Mo (AMS 5629)
The chemical composition of 13-8Mo Stainless Steel per AMS 5629 is precisely controlled to achieve its outstanding properties:
| Element | Weight % |
|---|---|
| Chromium (Cr) | 12.25 – 13.25% |
| Nickel (Ni) | 7.50 – 8.50% |
| Molybdenum (Mo) | 2.00 – 2.50% |
| Aluminum (Al) | 0.90 – 1.35% |
| Carbon (C) | 0.05% max |
| Manganese (Mn) | 0.10% max |
| Silicon (Si) | 0.10% max |
| Phosphorus (P) | 0.010% max |
| Sulfur (S) | 0.008% max |
| Nitrogen (N) | 0.010% max |
| Iron (Fe) | Balance |
The addition of Molybdenum (2.00–2.50%) significantly enhances the alloy’s resistance to pitting corrosion and provides secondary hardening effects. Aluminum (0.90–1.35%) serves as the primary precipitation-strengthening element, forming NiAl intermetallic compounds (β-phase) that deliver exceptional age-hardening capabilities.
Mechanical Properties of 13-8Mo
13-8Mo Stainless Steel offers a wide range of mechanical properties that can be tailored through various single-cycle low-temperature aging treatments. The following are typical mechanical properties for 13-8Mo Bar stock per AMS 5629:
| Condition | Ultimate Tensile Strength (ksi) | 0.2% Yield Strength (ksi) | Elongation (%) | Hardness (HRC) |
|---|---|---|---|---|
| H950 | 220 | 205 | 10 | 45 |
| H1000 | 205 | 190 | 10 | 43 |
| H1025 | 185 | 175 | 11 | 41 |
| H1050 | 175 | 165 | 12 | 40 |
| H1100 | 150 | 135 | 14 | 34 |
| H1150 | 135 | 90 | 14 | 30 |
In metric units, 13-8Mo in the H950 condition achieves a minimum yield strength of 1413 MPa and a minimum tensile strength of 1517 MPa. The alloy exhibits excellent ductility and toughness in large sections in both longitudinal and transverse directions. The density of 13-8Mo is approximately 7.76 g/cm³.
