TYPE
Basic coated electrode for heat resistant stainless steels
APPLICATIONS
Common applications include industrial furnaces, annealing chambers, fused salt treatment installations and boiler parts, as well as heat exchangers..
PROPERTIES
For welding heat-resistant austenitic steels of the 25% Cr, 20% Ni types. 4842 Kb 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 general the alloy is heat resistant up to 1200°C. This alloy can withstand relatively severe thermic shock, and is superior to type 309 L.
SUITABLE FOR
1.4823, 1.4826, 1.4828, 1.4832, 1.4840, 1.4841, 1.4846, 1.4848, 1.4837, 1.4710, 1.4713, 1.4724, 1.4726, 1.4742, 1.4745, 1.4762, 1.4845, 1.4849 heat resistant stainless steel, AISI 305, 310, 314, ASTM A297 HF, A297 HJ
