| Product Model:ER49-1 |
| Description: |
| ER49-1 a kind of mild steel copper coated welding wire with excellent welding properties and the welding seams have very high impact resistance at low temperature. |
| Application: |
| Used to weld ship building steel(A32, E32, D32, A36, E36, D36) and mild steel products with strength at 490N/mm2degree,such as mild alloy steel 16Mn, 15Mn ect to produce furnace,tubes for vessel,container building etc. |
