Alloy Steel Carbon Steel Stainless Steel Cast Flange Casting Services Product

As a specialized manufacturer in fluid system components, we provide comprehensive casting services for flanges using alloy steel, carbon steel, and stainless steel materials. Our manufacturing expertise combines advanced casting technology with precision machining to deliver flanges that ensure reliable performance, exceptional durability, and perfect sealing in various piping and pressure system applications.

Material Excellence and Performance Characteristics

We utilize three primary material groups specifically engineered for flange applications:

Alloy Steel Flanges
Our alloy steel flanges, primarily ASTM A217 WC6 and WC9 grades, offer superior mechanical properties with tensile strength of 485-760 MPa and yield strength of 275 MPa minimum. These materials demonstrate excellent high-temperature performance, good creep resistance, and enhanced corrosion resistance compared to standard carbon steels, making them ideal for high-pressure and high-temperature applications.

Carbon Steel Flanges
We produce carbon steel flanges using ASTM A216 WCB grade, providing reliable performance with tensile strength of 485-655 MPa and yield strength of 250 MPa minimum. The material offers good weldability, excellent impact strength at service temperatures, and reliable performance in various industrial environments while maintaining cost-effectiveness.

Stainless Steel Flanges
Our stainless steel flanges utilize 304, 316, and 316L grades, offering exceptional corrosion resistance with tensile strength of 515 MPa minimum. The 316 and 316L grades, containing 2-3% molybdenum, provide superior resistance to pitting and crevice corrosion in chloride environments, ensuring long-term reliability in aggressive media applications.

Advanced Casting Manufacturing Process

Our production methodology employs sophisticated casting techniques:

Sand Casting Technology
