Carbon Steel A694 Flanges are robust, forged flanges designed for high-pressure transmission in oil, gas, and petrochemical pipelines. Shalan Steel, a trusted manufacturer and supplier located in Kuala Lumpur, Malaysia, provides top-quality A694 flanges in a variety of classes and sizes to cater to the rigorous demands of industrial applications. These flanges are popular throughout Malaysia and Southeast Asia, known for their remarkable strength, toughness, and durability even in extreme temperatures and pressures.
Made from carbon steel, ASTM A694 flanges boast enhanced mechanical properties thanks to heat treatment. Depending on the specific grade—like F42, F52, F60, F65, or F70—the yield strength can range from 290 MPa to over 485 MPa, with tensile strengths reaching beyond 415–570 MPa. Typically, these flanges come in normalized or quenched and tempered conditions, making them compatible with high-pressure piping systems for secure connections and leak-proof performance.
