A387 Grade 11 Class 2N Chemical Composition and Mechanical Properties
A387 Grade 11 Class 2N is a chromium-molybdenum alloy steel widely used in pressure vessels and heat exchanger shells. The "N" indicates that the material has undergone normalization, a heat treatment process that enhances its mechanical properties, making it suitable for applications requiring durability and resistance to high temperatures and corrosion.
| Element | Composition (%) |
|---|---|
| Carbon (C) | ≤ 0.05–0.15 |
| Manganese (Mn) | 0.30–0.60 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Silicon (Si) | 0.50 max |
| Chromium (Cr) | 1.00–1.50 |
| Molybdenum (Mo) | 0.45–0.65 |
The chromium and molybdenum content provides excellent resistance to oxidation, hydrogen attack, and other high-temperature corrosive environments.
| Property | Value |
|---|---|
| Tensile Strength | 515–690 MPa (75,000–100,000 psi) |
| Yield Strength | ≥ 310 MPa (45,000 psi) |
| Elongation | ≥ 18% |
| Impact Test | Passed at -20°C |
With its superior mechanical properties, A387 Grade 11 Class 2N is ideal for use in heat exchanger shells that operate under extreme pressures and temperatures.
SA213 T11 Mechanical Properties
SA213 T11 is a ferritic alloy steel used for seamless tubes in heat exchangers and boilers due to its outstanding performance in high-temperature and high-pressure environments. Its chemical composition and mechanical properties make it a perfect match for A387 Grade 11 Class 2N shells.
| Property | Value |
|---|---|
| Tensile Strength | ≥ 415 MPa (60,000 psi) |
| Yield Strength | ≥ 205 MPa (30,000 psi) |
| Elongation | ≥ 30% |
| Hardness | ≤ 85 HRB |
The combination of strength, ductility, and resistance to high-temperature oxidation makes SA213 T11 tubes ideal for efficient heat transfer in demanding applications.
