Promax 309LSi Stainless Steel Mig Wire 12.5kg
Key Features
- Suitable for dissimilar metal welding & buffer layers before hard-facing
- A G 23 12 LSi/ER 309LSi type solid MAG welding wire, supplied precision layer wound
- Deposits a low C-23Cr12Ni weld metal
- Suitable for use with Ar+2%O2 or Ar+0.5-5%CO2 mixed shielding gases
- Used for the welding of stainless steels to mild and medium tensile steels
- Ideal for dissimilar metal welding, or as a buffer layer under hard-facing
- Used for depositing intermediate (buffer) layers on steel prior to hard-facing or depositing 308 or 316 grade stainless steel
- Also used for the welding of clad steels where service temperatures are below 300°C
- The weld metal has a delta-ferrite content of ~12% resulting in a high resistance to hot cracking
- The increased silicon content results in increased weld pool fluidity to give a smooth deposit appearance
- Available in 0.8mm and 0.9mm spools
