Discussion On Long Range Ordering Of Ni-Based Alloys Used In BWR Environment

Product Number: ED22-18533-SG

Author: Yun Wang, Ryoji Obata, Shinichi Ishioka

Publication Date: 2022

Due to the strength, ductility, fracture toughness, corrosion resistance and especially the coefficient of thermal expansion, which is between stainless steel and low alloy steel, Ni-based alloys are used as weld metals in BWR and ABWR internals. Ni-based alloys with high chromium (Cr) concentration, such as Alloy 52 (Cr: 28-31.5 wt.%), Alloy 52i (Cr: 26-28 wt.%) and so on are expected to have higher SCC resistance than 182 (Cr: 13-17 wt.%) and Alloy 82 (Cr: 18-22 wt.%) in BWR environment.

SCC of Alloy 152/52 Welds Defects, Repairs, Dilution Zones and HAZs in PWR Water

Product Number: ED22-17243-SG

Author: Peter L. Andresen, Chris Wax

Publication Date: 2022

$20.00

Stress corrosion cracking (SCC) has been observed for over six decades in light water reactors structural components, with wide variations in the rate of SCC initiation and crack growth. Newer materials have been adopted in the last three decades, primarily the ~30% Cr Alloy 690 (UNS N06690) and its weld metals, Alloy 52 (UNS W86052) and Alloy 152 (UNS W86152). These materials were initially viewed as immune to SCC, but are now recognized to be susceptibility to SCC, and can exhibit high growth rates in some conditions.
