INCO-WELD® 686CPT AWS 5.14 ERNiCrMo-14


INCO-WELD® 686CPT Filler Metal

INCO-WELD® 686CPT Filler Metal is used for gas-tungsten-arc and gas-metal-arc welding of duplex, super-duplex and super-austenitic stainless steels, as well as nickel alloys such as UNS N06059 and N06022, INCONEL® alloy C-276, and INCONEL® alloys 22, 625, and 686. It is also capable of being used to deposit overlays of outstanding corrosion-resistance onto a range of steels. The high alloy levels (of Cr + Mo + W) result in increased resistance to pitting, crevice and general corrosion. INCO-WELD® 686CPT Filler Metal is of great value for service environments requiring general corrosion- resistance in HCI or sulfuric acid; for resistance to crevice corrosion in hot, concentrated acid chloride solutions such as sulfur dioxide saturated NaCl solutions and oxidizing chloride solutions and for resistance to intergranular attack, after sensitization in highly oxidizing environments. Submerged arc welding can be done with INCOFLUX® NT120 Submerged Arc Flux.
