| High Light | Niobium Stabilized WP347H Tee ，High Carbon Creep Resistant Fitting ，Elevated Temperature Equal Tee | ||
TOBO supplies ASTM A403 WP347H niobium (columbium) stabilized stainless steel equal tees for elevated temperature applications. The higher carbon content combined with niobium stabilization provides superior creep strength and oxidation resistance at temperatures exceeding 540°C (1000°F), making it the preferred choice for high-temperature boiler and pressure vessel piping systems.
