Grade EN 1.4980
Grade EN 1.4980
Material 1.4980 / Alloy 286 is an iron-nickel-chromium alloy that enables precipitation hardening through the addition of aluminum and titanium. This forms intermetallic phases that significantly increase the strength of the alloy. In addition, molybdenum improves the mechanical properties and resistance to creep at high temperatures.
Thanks to this composition, material 1.4980 / Alloy 286 offers high heat resistance and excellent corrosion resistance at temperatures up to 700 °C. This means that material 1.4980 / Alloy 286 outperforms both low-alloy steels and common stainless steels. Even at temperatures up to 800 °C, the properties of material 1.4980 / Alloy 286 remain very good.
NICROMAL supplies material 1.4980 / Alloy 286 as sheet metal, round steel, rings, round bars, or custom-made parts according to your specifications.

Questions about grade 1.4980
Material 1.4980 / Alloy 286 offers high heat resistance up to 700°C and very good corrosion properties in oxidizing media up to 700°C.
The density of material 1.4980 / Alloy 286 is 7.94 kg/m³.
Material 1.4980 / Alloy 286 should be machined in the annealed state if possible. Due to its tendency to work harden, a low cutting speed should be selected. The cutting depth should be selected so that a previous hardened zone can be undercut. If possible, the cutting tool should be kept in constant contact.
