Our ASTM A403 WP321/321H stainless steel reducers are titanium-stabilized austenitic stainless steel fittings engineered for superior performance in high-temperature applications. The titanium addition prevents chromium carbide precipitation during welding and service at elevated temperatures up to 800°C, making them the preferred choice for heat exchangers, boiler systems, and thermal processing equipment.
