INCONEL Filler Metal 52M

INCONEL Filler Metal 52M is used for gas-tungstan-arc and gas-metal-arc welding of INCONEL alloy 690 and the overlaying of carbonsteels and stainless steels to provide a nickel-chromium alloy corrosion resistant surface. The high chromium level provides excellent resistance to stress corrosion cracking in the nuclear, pure water environment. The product can also be used in applications requiring resistance to oxidizing acids. It is useful for dissimilar joints involving INCONEL and INCOLOY alloys.

This product cantains Boron and Zirconium to minimize the tendency for ducitility-dip cracking, while it is especially resistant to oxidie "floaters" and inclusions.
