Description
308Mn – E307 Stainless Steel Welding Electrodes – 3.25 mm
308Mn – E307 is an austenitic, rutile-coated electrode designed for the joining and overlay of steels and Manganese steels. It is particularly suitable for joining dissimilar steels, from construction steel to stainless steel, and can be used as a cushion layer before hard facing. The electrode is characterized by its work-hardening deposit and is non-magnetic. It is commonly used in applications such as civil engineering, railways, cement works, digger buckets, and crusher jaws.
Features & Benefits:
- Versatile Welding: Suitable for joining and overlaying steels and Manganese steels.
- Dissimilar Steel Joining: Ideal for joining dissimilar steels, including construction steel to stainless steel.
- Wear Resistance: Acts as a wear-facing electrode against severe impact.
- Work-Hardening: The deposit is work-hardening, ensuring durability.
- Non-Magnetic: Suitable for applications where magnetism is a concern.
Common Applications:
- Joining of dissimilar steels
- Construction steel to stainless steel
- Cushion layers before hard facing
- Civil engineering
- Railways
- Cement works
- Digger buckets
- Crusher jaws
Weld with a short arc and a slight inclination. Do not pre-heat Manganese steel due to sensitivity to hot cracking. Rebake at 300°C for I hour, should this be required
