ASTM A517 Grade E High-Strength Quenched & Tempered Boiler & Pressure Vessel Steel Plate Application Introduction
ASTM A517 Grade E is engineered for welded pressure equipment requiring high strength and good toughness. It is widely used in the oil & gas, chemical, and power industries.

- Excellent for thick-walled vessels where weight reduction is critical.
Product Applications: High-pressure boilers and steam drums, Ammonia synthesis converters, Hydrocracker reactors, LPG storage vessels, Thick-walled heat exchangers, High-pressure piping systems
Processed into products: Shell courses and heads, Tube sheets and flanges, Welded nozzles and reinforcements, Manway covers and blind flanges, Structural supports for heavy vessels
Application industries: Oil & Gas (pressure vessels, separators), Petrochemical (reactors, columns, heat exchangers), Power Generation (boilers, steam drums), Chemical Processing (high-pressure storage), Offshore Engineering (platform structural components)
ASTM A517 Grade E High-Strength Quenched & Tempered Boiler & Pressure Vessel Steel Plate Similar/Alternative High-Strength Pressure Vessel Steels
| Country/Region | Standard | Grade | Remarks |
|---|---|---|---|
| Europe | EN 10028-6 | P690Q (1.8880) | Similar high strength (min 690 MPa YS), but base composition differs (Mn-Ni-Cr-Mo); Ni lower. Often used as alternative in pressure vessels. |
| Japan | JIS G3115 | SPV490 | Lower yield strength (min 490 MPa); for less demanding applications; can substitute where design allows reduced strength. |
| China | GB 19189 | 12Cr2Ni1Mo | High-strength Cr-Ni-Mo grade, contains vanadium; approximate replacement for A517 Grade E in some applications, with slight strength/toughness trade-offs. |
| USA | ASTM A543/A543M | Type B Class 2 | Ni-Cr-Mo-V quenched & tempered; yield strength ~100 ksi, but additional vanadium for hardenability; suitable for similar conditions. |
Notes:
Welding considerations: Preheat temperature typically 200–300°F (95–150°C) depending on thickness; interpass temperature maintained. Low-hydrogen processes (SMAW, SAW, GMAW) recommended. Post-weld heat treatment (PWHT) often applied at 1100–1200°F (590–650°C) to relieve stress. Impact testing (Charpy V-notch) may be ordered as a supplementary requirement (S5 in ASTM A20/A20M) for low-temperature service. Plates are ultrasonically inspected per ASTM A435/A435M or A578/A578M if specified.
