DAIKOFCW 82

These weld metals lack a direct equivalent parent material, but their composition shares similarities with Inconel™ 600. The inclusion of Mn and Nb enhances their resistance to hot cracking, enabling them to withstand dilution by various combinations of nickel-base and ferrous alloys. They maintain consistent properties over a broad service temperature range, spanning from –269°C to temperatures exceeding 900°C. Applications encompass the welding of heat-resisting nickel-base alloys for use in furnace equipment, reaching temperatures up to approximately 900°C.Also employed for mixed welds involving different nickel-base alloys, such as Monel 400, and stainless, low alloy, or C-Mn steels, eliminating the need for preheating. Moreover, they find utility in transition welds between creep-resisting ferritic and austenitic steels, like 2CrMo and 316H, for prolonged service at elevated temperatures in petrochemical and power generation plants. Ideal for cryogenic applications involving 3% or 5% Ni steels in vessels and pipework operating at or below –100°C. Stress relief is optional. Preheat and PWHT depend on the base material, with no preheat needed for most nickel-base materials
