The ASTM A387 is the standard specification for pressure vessel plates made of Cr-Mo alloy steel. This type of plate is mainly intended for usage in applications that involve elevated temperature service, where resistance to oxidation and improved mechanical properties are required. These properties make the plates ideal for use in high-temperature environments.
At Gnee, we offer A387/SA387 Grades specially designed for refineries, power plants, and chemical industries. We provide them in Class 1 or 2 and more to meet the diverse industrial needs.
The A387/SA387 Alloy Steel Plate is a carefully crafted product with various chemical and mechanical properties. The chemical properties of the plate can be broken down into different grades, which include grade 5, grade 9, grade 11, grade 12, and grade 22. These grades have different carbon content, manganese content, phosphorus content, sulfur content, silicon content, chromium content, and molybdenum content.
| Grades | Carbon | Manganese | Phosphorus | Sulfur | Silicon | Chromium | Molybdenum |
|---|---|---|---|---|---|---|---|
| Grade 5 | 0.15 max | 0.25-0.66 | 0.035 | 0.030 | 0.55 max | 3.9-6.1 | 0.40-0.7 |
| Grade 9 | 0.15 max | 0.25-0.66 | 0.030 | 0.030 | 1.05 max | 7.9-10.1 | 0.85-1.15 |
| Grade 11 | 0.04-0.17 | 0.35-0.73 | 0.035 | 0.035 | 0.44-0.86 | 0.94-1.56 | 0.40-0.7 |
| Grade 12 | 0.04-0.17 | 0.35-0.73 | 0.035 | 0.035 | 0.13-0.45 | 0.74-1.21 | 0.4-0.65 |
| Grade 22 | 0.04-0.15 | 0.25-0.66 | 0.035 | 0.035 | 0.5 max | 1.88-2.62 | 0.85-1.15 |
The mechanical properties of the plate can also be broken down into different grades, which include grade 5, grade 9, grade 11, grade 12, and grade 22. These grades have different tensile strength, yield strength, elongation in 200mm, and elongation in 50mm depending on their class type.
| Grades | Class 1 | Class 2 |
|---|---|---|
| Grade 5 | Tensile Strength (ksi): 60-85 | Tensile Strength (ksi): 75-100 |
| Grade 9 | Tensile Strength (ksi): 60-85 | Tensile Strength (ksi): 75-100 |
| Grade 11 | Tensile Strength (ksi): 60-85 | Tensile Strength (ksi): 70-90 |
| Grade 12 | Tensile Strength (ksi): 50-80 | Tensile Strength (ksi): 60-85 |
| Grade 22 | Tensile Strength (ksi): 60-85 | Tensile Strength (ksi): 75-100 |
| Yield Strength (ksi): 30 | Yield Strength (ksi): 45 | |
| Elongation in 50mm (%): 18 | Elongation in 50mm (%): 18 | |
| Grade 11 | Elongation in 200mm (%): 19 | Elongation in 200mm (%): 18 |
| Grade 12 | Reduction of area in %: 45 | Reduction of area in %: 45 |
| Grade 22 | Reduction of area in %: 45 | Reduction of area in %: 45 |
