Stainless Steel Electrodes
ES 310 B A5.4: E 310 –15 / EN 1600: E 25 20 B 2 2
Description
ES 310 B Basic electrode, core wire alloyed for analogous, heat resisting rolled, forged and cast steels e.g.in annealing plants, hardening plants, steam boiler construction, the crude oil industry and the ceramics industry. Joint welds in heat resisting CrSiAl steels exposed to sulphurous gases should be given a final layer deposited by means of ES 245. Scaling resistant up to +1200 °C. Cryogenic resistance down to -196 °C. The service temperature range between +650 and +900 °C should be avoided owing to the risk of embirittlement
