The ASTM A537 standard is the specification for heat-treated pressure vessel plates for the applications of fusion welded pressure vessels and structures. ASTM A537 plate covers three grades: A537 Class 1, A537 Class 2, A537 Class 3. A537 Class 1 material is available as Normalized and A537 Class 2 material is available as Quenched and Tempered.
ASTM A537 plate chemical composition:
| Grade | C | Mn | P | S | Si | Cu | Ni | Cr | Mo | |
| A537 | Heat analysis | 0.24 | 0.70-1.60 | 0.35 | 0.35 | 0.15-0.50 | 0.35 | 0.25 | 0.25 | 0.08 |
| Product analysis | 0.64-1.72 | 0.13-0.55 | 0.38 | 0.28 | 0.29 | 0.09 |
ASTM A537 plate is typically applied in pressure vessels designed for moderate and lower temperature service requiring excellent notch toughness. The maximum thickness of ASTM A537 plate is 100 mm for A537 Class 1 and 150 mm for A537 Class 2 and A537 Class 3.
