GeKa – ER 309LSi Stainless Wire (0.8mm) 12.5kg

Description

GeKa – ER 309LSi Stainless Wire (0.8mm) 12.5kg

GeKa ER 309LSi is a solid austenitic stainless wire designed for dissimilar joint welding of stainless and CMn steels. It is particularly suitable for buffer layers before hardfacing and is applicable on a range of materials including ferritic Cr or austenitic CrNi steels, austenitic manganese steels, unalloyed high-strength steels, and heat-treated steels.

Features & Benefits:

• Versatility: Ideal for welding austenitic stainless steels and joint-welding of different metals.
• Buffer Layers: Suitable for creating buffer layers before hardfacing.
• Diverse Applications: Can be used for joint-welding of corrosion-resistant stainless steels to each other or to low-alloyed steels, and in welding coated steels.
• Shielding Gases: Compatible with MAG shielding gases; specifically Ar+%2.5 O2 or Ar+%2.5 CO2 mixed gases.

Common Applications:

• Welding of austenitic stainless steels
• Joint-welding of different metal types
• Buffer layers before hardfacing
• Welding coated steels
• Joint-welding of corrosion-resistant stainless steels to various metals
