| Product name：KS-309 |
| Classification：A 5.4 / E309-16 |
  |
- Weld metal is 23.5%Cr-13%Ni.
- The proper ferrite contents in the weld metal can prevent crack at high temperature.
- It is suitable for welding AISI 309S and dissimilar metals (mild steel and stainless steel).
- It is used as the buttering layer when welding dissimilar metals, which provides excellent performance for corrosion resistant surface between mild steel and hard-to-weld steel.
