ASTM A517 Plate Grades

ASTM A517 has 8 grades (A, B, E, F, H, P, Q, and S) with identical mechanical properties but different chemistries and thickness limits.

Grade A

Grade A is a high-strength alloy steel plate that goes through quenching and tempering for pressure vessels.

Grade B

Grade B is a high-strength alloy steel plate for pressure vessels, available in thicker sections than Grade A while maintaining good toughness.

Grade E

Grade E provides higher yield strength than Grades A and B that makes it suitable for pressure vessels requiring improved load-bearing capacity.

Grade F

Grade F provides similar strength to Grade E but with enhanced impact toughness for more critical service conditions.

Grade H

Grade H is made for pressure vessels that need high strength and reliable performance at lower temperatures.

Grade P

Grade P provides high strength levels for pressure vessel applications where weight reduction and efficiency are important.

Grade Q

Grade Q is a very high-yield plate used in heavy-duty pressure vessels that demand superior strength and durability.

Grade S

Grade S is engineered for applications requiring high strength combined with improved notch toughness, especially in low-temperature environments.
