Why choose ABRATIG 276 filler metal?
ERNiCrMo-4 TIG wire, better known as ABRATIG 276, is a high-end nickel-based filler metal designed for extreme environments. Here’s why we use it:
- Outstanding chemical resistance
TIG 276 is the filler metal equivalent for Hastelloy C-276 alloy.
It offers extreme resistance to corrosion, including :
- Strong acids (hydrochloric, sulfuric, phosphoric, nitric…)
- Oxidizing and reducing media
- Environments containing chlorine, salts, aggressive organic compounds, etc.
- High-temperature resistance
- Highly temperature-stable, even above 1000°C.
- Resists oxidation, carburization and sulfurization.
- Ideal for severe chemical or thermal applications.
- Welding versatility
Suitable for welding :
- Parts in Hastelloy C, C-22, C-276, etc.
- High-alloy inconel or stainless steels
- Complex cases of dissimilar welding (e.g. stainless steel ↔ nickel, or stainless steel ↔ carbon steel)
- Good arc behavior, regular melting, little cracking.
