Steel Flange Connector

 This Steel Flange Connector is a critical joining component designed for high‑pressure piping systems, fluid transmission lines, and structural connections in industrial applications. It is manufactured by our in‑house Lost‑Wax Casting (Investment Casting) + CNC precision machining process. The use of ZG42CrMo cast alloy steel provides an excellent balance of high tensile strength, excellent toughness, good hardenability, and reliable performance under elevated temperatures and cyclic loading. The lost‑wax casting process ensures tight dimensional tolerances, smooth surface finish, and the ability to form complex internal geometries — all critical for flange connectors requiring leak‑proof sealing, precise bolt hole alignment, and long‑term reliability in harsh environments.

Our one‑stop approach — covering mold design, lost‑wax casting, CNC machining, surface treatment (anti‑rust oil, primer painting, or zinc plating), and engineered packing — delivers a ready‑to‑install flange connector that meets high‑strength mechanical requirements and withstands vibration, pressure spikes, thermal cycling, dust, moisture, and corrosive media.
