ES 309 MoL A5.4: E 309 MoL –17 / EN 1600: E 23 12 2 LR 32
Description
ES 309 MoL is a low carbon austenitic stick electrode with rutile coating . High crack resistance with hard- to weld materials, austenite- ferrite joints and weld claddings is achieved through the increased ferrite content ( F N-20 ) in the weld metal. Particularly good fine welding properties and excellent. AC weld ability characterise this product. For operating temperatures up to +300 °C , for the first layer of weld cladding up to +400°C.
