Stainless Steel Wires
Bostrand LW1
Bostrand LW1 is a general purpose mild steel copper coated MAG wire. De-oxidised with manganese and silicon, it produces quality welds with excellent radiographic and mechanical properties. Bostrand LW1 is ideal for welding most mild and carbon-manganese steels e.g. Lloyd's grade A to EH.
