This program to produce overlays, with corrosion resistance to coal gasification atmospheres at 1800/sup 0/F, is in its early stages. The first quarter was used to obtain the materials required for the program and to begin welding. All materials needed for the program have been received or are on order. The substrate materials, AISI 304L, AISI 310 and INCOLOY alloy 800H and the AWS-ER309 filler metal have been obtained. The INCONEL Filler Metal 72 (44%Cr-/sup 0/.3%Ti-bal. Ni) and the experimental R139 filler metal (31%Cr-3%Al-15%Fe-bal. Ni) are undergoing processing at Huntington Alloys, Inc. Overlaying of the AISI 304L substrate with the AWS-ER309 filler metal is complete. Three welding processes were used without difficulty. These were: submerged-arc, gas tungsten-arc with hot wire and gas metal-arc. The overlays were free from surface defects.
