Detail Information

ASTM A517 Grade Q quenched and tempered alloy steel plate for boilers and other pressure vessels

General Product Description

ASTM A517 Grade Q is a high-strength, quenched and tempered alloy steel plate intended for pressure vessel applications. A517 Grade Q is available in thicknesses up to 3.6 in. and has a minimum yield strength of 100 ksi up to 2.5 in. thick and 90 ksi for plates greater than 2.5 in. thick to 3.6 in. thick. ASTM A517 Grade Q also has required Charpy V-notch impact property requirements.

1) See specification A20 for elongation adjustment.

2) Reduction in area for 1.5 inches wide rectangular tension specimen.

3) Reduction in area for 0.5 inch wide round tension specimen.

Mechanical Testing

Charpy V-Notch Impact Properties: A trasverse Charpy V-notch lateral expansion of 0.015” [0.38 mm] in individual specimens is required. The test temperature shall be agreed upon between the manufacturer and purchaser. Please inquire for required Charpy V-notch test temperature and for other specified minimum impact property requirements.
