AWS 5.14 ERNiCrFe-7A
INCONEL® Filler Metal 52M
INCONEL® Filler Metal 52M is used for gas-tungsten-arc and gas-metal-arc welding of INCONEL® 690, and the overlaying of carbon steels 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 contains Boron and Zirconium to minimize the tendency for ductility-dip cracking, while it is especially resistant to oxide “floaters” and inclusions.
