3. ASTM A672 Chemical Composition
| Grade / Plate Material | C (%) | Mn (%) | P (%) | S (%) | Si (%) |
|---|---|---|---|---|---|
| B60 / ASTM A515 Gr.60 | ≤ 0.24 | 0.79 - 1.33 | ≤ 0.025 | ≤ 0.025 | 0.13 - 0.45 |
| C65 / ASTM A516 Gr.65 | ≤ 0.24 | 0.79 - 1.33 | ≤ 0.025 | ≤ 0.025 | 0.13 - 0.45 |
| C70 / ASTM A516 Gr.70 | ≤ 0.20 | 0.79 - 1.33 | ≤ 0.025 | ≤ 0.025 | 0.13 - 0.45 |
| C60 / ASTM A516 Gr.60 | ≤ 0.23 | 0.79 - 1.30 | ≤ 0.025 | ≤ 0.025 | 0.13 - 0.45 |
Note: ASTM A672 chemistry properties are determined by the corresponding base plate standard (e.g. ASTM A515 for high temp, or ASTM A516 for moderate temp).
4. ASTM A672 Mechanical Properties
| Grade / Plate Material | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Typical Classes |
|---|---|---|---|---|
| B60 / ASTM A515 Gr.60 | ≥ 220 | 415 – 550 | ≥ 21 | As per class |
| C65 / ASTM A516 Gr.65 | ≥ 240 | 450 – 585 | ≥ 20 | As per class |
| C70 / ASTM A516 Gr.70 | ≥ 260 | 485 – 620 | ≥ 20 | As per class |
| C60 / ASTM A516 Gr.60 | ≥ 220 | 415 – 550 | ≥ 20 | As per class |
A672 WELDED PIPES CLASSES
- Class 10 – Radiographic testing only
- Class 11, 12, 13 – Radiographic + transverse tension + weld bend test
- Class 22 / 32 – As above + impact testing at required temperature as per client requirement
- Properties are tested on base metal and weld seam as per class requirement. Mechanical properties correspond to the base plate material after welding and required heat treatment as determined by the Class.
5. ASTM A672 Heat Treatment Parameters
The heat-treatment temperatures are governed by the specific Class selected and the base-plate specification requirements.
