Stainless Steel

ARF SS-309


  • Classifications :
    AWS : E 309 16
    IS      : E 23.12 R 16

  • Characteristics :
    A medium heavy coated, rutile type all position electrode giving 25/12 deposit which has excellent corrosion and oxidation resistance in continuous service upto 1100'C. Gives a quiet and stable arc, low spatter, smooth weld bead and easily detachabble slag and finelly rippled weleds of radiographic qulity.

  • Applictions :
    Stainarc 309 is ideally suited for Weding of stainless steel of A ISI grade, 18/8 stainless steel tomild steel, sheet lining of 12% Cr steel to mild steels, overlays of ferrite steel and difficult to weld steels. Building up mild steel to improve wear resistance and for building up worn part of wear resisting steels.

  • All Weld :
    C = 0.06-0.15
    Mn = 0.5-2.5

  • Meetal properties :
    Si = 0.90 Max
    S = 0.03 Max
    P = 0.03 Max
    cr = 22.0-25.0
    Ni = 12.0-14.0

  • All Weld :
    UTS = 560 min N/mm2

  • Mechanical properties :
    Elong = 30 Min
    CVN impact Value(J)at 27+-2'C:50-100

  • Precautions :
    Ensure that the electrodes are perfectly dry before use. Moist electrodes should be redried at 150'C for 1 hour. Use short arc, striger beads and low current.
