DAIKOWT 82

These welding metals do not have a directly equivalent base material, however, their composition is similar to Inconel™ 600. The addition of Mn and Nn is designed to ensure high resistance to hot cracking and dilution tolerance, compatible with numerous combinations of ferrous and nickel-based alloys. These metals maintain stable properties over a wide range of operating temperatures, spanning from –269°C up to beyond 900°C. The main applications include heat-resistant nickel-based alloys, ideal for use in
furnace equipment up to about 900°C. This material is also suitable for dissimilar welding between most nickel-based alloys, including Monel 400 and stainless steels, low alloy or C-Mn steels without the need for preheating. Further applications include transition welds between creep-resistant ferritic steels and austenitic steels, such as 2CrMo and 316H, for long-term high-temperature service in petrochemical and power generation plants. Additionally, it is ideal for
low temperature applications, such as cryogenic tanks or pipelines operating at –100°C or below, made with steels containing 3% or 5% Ni. Stress relieving treatment can be performed if necessary. The requirements for preheating and post weld heat treatment (PWHT) depend on the base material being welded. For most nickel-based alloys, no preheating is required.
