PMET 980 – B50TF193 – Tribaloy® T800 welding wire for gas turbine engine blades.
PMET 980 (Tribaloy® T800) is a solid hardfacing wire consisting of cobalt, molybdenum, chromium, and silicon. PMET 980 attains its oxidation, corrosion, and galling resistance from its hard laves phase which is dispersed in a softer solid solution eutectic.
- DMR 34.071
- Tensile strength – less than 70,000 PSI
- Elongation – Nil
- Hardness – 52-62 HRC
- PMET 980 has found acceptance in a number of applications where galling, abrasion, oxidation, and corrosion are a problem. Applications include pump shaft sleeves, computer hard drives, gas turbine blade shrouds and bases.
