G-TECH 840 SX
SMAW
- DISSIMILAR STEELS
Description
Basic coated electrode for Inconel 600 and 601 alloys with 140% recovery
There is no equivalent base metal, but the composition is related to Inconel 600. Mn and Nb are added in order to give high resistance to hot cracking and tolerance to dilution by combination with ferrous alloys. This product has stable properties for service from -269°C to approx. 800°C. Applications include welding heat-resistance alloy in furnace equipment, dissimilar welds between nickel base alloys (including Monel) and stainless steels, low alloy and carbon steels. Also suitable to weld Cr-Mo steels with austenitic steels (e.g. 308H) for service at elevated temperature in petrochemical plant. It is also used for low temperature applications such as 3% and 5% Ni steels.
