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

Detailed

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

 

General Product Description

ASTM A517 Grade B is a quenched and tempered alloy steel plate intended for use in fusion welded boilers and other pressure vessels. A517 Grade B has a minimum yield strength of 100 ksi [690 MPa] and a minimum transverse Charpy V-notch lateral expansion of 0.015 inches (0.38 mm).

Applications

Typical applications for A517 Grade B include unfired pressure vessels and tanks.

1) Refer to ASTM A20/A20M for Elongation adjustments based on plate thickness.

2) Reduction in area for 1.5 inches wide rectangular tension specimen. For plate thicknesses of 0.750 inches and less, the test specimen must be a 1.5 inch wide rectangular specimen.

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

Mechanical Testing

Charpy V-Notch Impact Properties: A transverse Charpy V-notch lateral expansion of 0.015 inches [0.38 mm] in individual specimens can be guaranteed to a minimum test temperature of -40°F [-40°C]. Please inquire for applications requiring lower test temperature guarantees for 0.015 inches [0.38 mm] minimum transverse lateral expansion and for other specified minimum impact property requirements. All test temperatures must be specified on each purchase order.

Tolerances

Thickness, width, and length tolerances for A517 Grade B steel plate are in accordance with the requirements of ASTM A20. The flatness tolerance for as- supplied product is ½ ASTM A20.

 

Delivery Conditions

ASTM A517 Grade B is supplied in the quenched and tempered condition.

 

Weldability

Welding of A517 Grade B shall be performed in accordance with the applicable welding code. Special welding consumables and welding procedures may be needed to meet specific requirements for a given application. Low hydrogen practices are strongly recommended, including the removal of surface moisture. A517 Grade B may be susceptible to reheat cracking in the heat-affected zone of welds during stress relieving or postweld heat treatment. As a result, SHUNFU recommends that a qualified welding engineer consider this potential before stress relieving weldments of this product. For additional welding information, please contact your SHUNFU representative.
