Stainless Steel

ARF SS-309-L


  • Classifications :
    AWS : E 309 L 16
    IS      : E 23.12 LR 16

  • Characteristics :
    Stainarc 309 L is a rutil basde, extra low carbon, all position electrode of 25/12 type for joining of stainless steel to mild steels,fore surfacing of mild steel. The weld metal has excellent mechanical properties and is of radiographic qualit. the weld metal resists oxidesn at elevated tempratures. Advantages: 1 Easy deslagging. 2 Extremely low spatter. 3 it is especially useful for Joining stainless to mild steel.

  • Applictions :
    Stainarc 309 is ideally suited for Weding of stainless steel of similar composition, for welding carbon steel to 18/8 variety of stainless steel for buffer layers on carbon steel before DEPOSITIONG THE STAINLESS STEEL WELD METAL OF required composition, for applying sheet lining of 12% Cr to mild steel shells and for joining problem steels. it is also used widely for surfacing of mild steel and for building up worn part of wear resisting steels.

  • All Weld :
    C = 0.03
    Mn = 0.5-2.5

  • Meetal properties :
    Si = 0.05 Max
    cr = 24
    P = 0.03 Max
    Ni = 12.8

  • All Weld :
    UTS = 580 min N/mm2

  • Mechanical properties :
    Elong(%) = 38 Min
    CVN impact Value(J)at 27+-2'C:50-100

  • Precautions :
    Redry moist electrodes st 200'C for one hour and cool slowly to 50'C-60'C for use. Restrict heat input during welding.
