Product Description

Alloy 52 welding wire filler rod Diameter 3.2mm for Alloy 52/152 Weldments

Alloy 52 welding wire / N14052 Alloy 52 contains 52% nickel and 48% iron and is widely used in the telecommunications industry. It also finds application in a wide variety of electronic applications, especially for glass seals. Also known as: Pernifer 502, NILO 50, Glass Seal 521 UNS K95050 N14052 ASTM F30

Alloy 600/182/82 welds are being replaced in many PWR systems with alloy 690/52/152 welds primarily for improved SCC resistance.


The Ductility-Dip Crack (DDC) existed in the nickel base alloy weldment during the high heat input GTAW cladding processwhere Alloy 52 is used as filler metal. This study is focused on the formation mechanism of DDC and its influencing factor. The formation temperature range is known asthe Ductility-Dip Temperature Range (DTR). The Failure Map of Alloy 52 was constructed by changing the temperature and strain parameter.The DDC test method wasdesignedthat stress is to be hold during the test. Grain boundary will rupture due to the DDCas the specimen temperature is raised to DTR.The Failure Map of strain versus temperature showed the trend of drop first and followed by rise as the temperature increase in DTR. A minimum of 2% for strain threshold value happenedat 900°Cwhich is the most DDC sensitive temperature. It can be speculated that the ductility of Alloy 52 were inadequate at 900°C when loaded.


Complicating this replacement is the known susceptibility of these high-Cr weld metals tosolidification and/or ductility dip cracking. Considerable expertise has been developed to minimize such problems for alloy 52/152 welds, however little is known about the distribution of aswelded cracks in service and concerns remain.



At present, in order to repair the damage of components or pipeline welding parts in nuclear power plants, in addition to replacing the materials with better corrosion resistance, such as Alloy 690 / 52 / 152 (4-7) and other nickel based materials with higher chromium content, the cladding method can also be used for protection; the cladding method is mainly to use alloy outside the welding and corrosion aging pipelines 52 / 152 and other high chromium electrodes can be directly covered or welded in the pipe. On the one hand, they can prevent new cracks from forming inside, and on the other hand, they can prevent the original cracks from growing outward and causing leakage of boiler water
