SMAW Stick electrodes
Rutile coated electrode for heat resistant stainless steels
Common applications include industrial furnaces, annealing chambers, fused salt treatment installations and boiler parts, as well as heat exchangers..
For welding heat-resistant austenitic steels of the 25% Cr, 20% Ni types. 4842 Ti has good general oxidation resistance, especially at high temperatures, due to its high Cr content. The alloy is fully austenitic and is therefore sensitive to hot cracking. The temperature limits for use under intermittent oxidation depend on cycle frequency. In no case shall a temperature of 1000°C be exceeded. This alloy can withstand relatively severe thermic shock, and is superior to type 309 L.
