Maintained under low-temperature conditions to prevent brittle fracture.
S355NL
Precision Machining
Strict control over flatness and bolt hole positional tolerances.
Ensuring sealing performance
Advantages
The forging process eliminates internal defects like porosity and voids, refines the metal grain structure, and aligns the grain flow circumferentially. This significantly enhances the flange’s tensile strength, bending resistance, and fatigue resistance, making it far superior to cast or welded alternatives.
