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
