Core Specifications

Key Benefits

• Versatile Compatibility: Welds mild steel, stainless steel, hardenable steel, armour steel, and 13%Mn Hadfield steel.
• Buffer Layer Excellence: Ideal for pre-hardfacing cast iron and listed steels, preventing cracking and ensuring adhesion.
• Time & Cost Savings: Eliminates frequent preheating, reducing production downtime.
• High-Strength Deposits: Austenitic weld metal with low carbon content for durability in critical applications.

Applications

Designed for demanding industrial tasks:
– Rail component repair (frogs, crossings, alloy rails)
– Crusher and earthmoving equipment hardfacing
– Dissimilar metal joining (e.g., stainless to mild steel)
– Cast iron buffer layers before hardfacing

Why Choose Our 307Si MIG Wire?

Unlike standard stainless steel wires, our 307Si formulation offers unmatched adaptability for dissimilar welding. Its work-hardening properties under service conditions ensure long-lasting performance in high-wear environments.

FAQ

Q: What gas should I use with this wire?
A: Use a standard argon-based shielding gas (e.g., 98%Ar/2%O2) for optimal results.
Q: Can it weld cast iron directly?
A: It excels as a buffer layer on cast iron before hardfacing, improving adhesion and reducing cracking.
Q: Is preheating necessary for rail repairs?
A: Often not required, but consult your welding procedure for specific material thicknesses.
