ASTM A612 grade steel is under ASTM A612/A612M technical standard, the specification for pressure vessel plates, carbon steel, high strength, for moderate and lower temperature service。 So of course, ASTM A612 grade steel is pressure vessel steel.
ASTM A612 grade pressure vessel steel chemical composition:
| ASTM A612 | C % | Si % | Mn % | P % | S % | Cu | Ni | Cr | Mo | V |
| Heat analysis | 0.25 | 0.15-0.50 | 1.00-1.50 | 0.025 | 0.025 | 0.35 | 0.25 | 0.25 | 0.08 | 0.08 |
| Product analysis | 0.29 | 0.13-0.55 | 0.92-1.62 | 0.38 | 0.28 | 0.29 | 0.09 | 0.09 |
ASTM A612 boiler steel plate pressure vessel steel sheet mechanical properties:
| Thickness | 0.5in [12.5mm] and under | Over 0.5in. to 1in.[Over 12.5 to 25mm] |
| Tensile strength, ksi [Mpa] | 83-150 [570-725] | 81-101 [560-695] |
| Yield strength,min,ksi [Mpa] | 50 [345] | 50 [345] |
| Elongation in 8in. [200mm], min, % | 16 | 16 |
