Description
The Hyundai Welding SR-625 3.2mm electrode is engineered for superior performance in welding nickel-based alloys, including Inconel 601 and 625, as well as 9% nickel steels. Its formulation ensures excellent corrosion resistance against crevice and pitting, as well as stress corrosion cracking (SCC). This makes it an optimal choice for industries involved in LNG storage tank fabrication, desulfurization processes, heat exchanger construction, and chemical carrier building.
Key Features:
- Exceptional corrosion resistance to crevice and pitting
- High tensile strength at elevated temperatures
- Reliable impact toughness at cryogenic temperatures
Typical Applications:
- Welding of Inconel 601 and 625 alloys
- Joining steel to nickel alloys
- Hardfacing of steel surfaces
- Fabrication of 9% nickel steel components
- Construction of LNG storage tanks and heat exchangers
