| Product name：KFW-317L |
| Classification：E317LT1-1/4 |
  |
- Weld metal is 19%Cr-13%N-3%Mo, which is suitable for welding AISI 317L steel.
- It provides good corrosion and heat resistance due to low C and additional Mo content.
- It provides good strength at high temperature and no post weld heat treatment required.
- It is ideal for welding critical chemical vessels for sulfuric and sulphurous acid.
