ANSI B16.5 Class 900 Flange

Typically, ANSI B16.5 Class 900 Flanges are made from high-grade carbon steel, stainless steel, or alloy steel, depending on the specific service requirements. Their chemical makeup generally includes carbon, manganese, silicon, phosphorus, and sulfur, with optional alloying elements like chromium, nickel, and molybdenum to boost strength and resistance to corrosion. Mechanically, these flanges are engineered for high-pressure ratings, providing excellent tensile and yield strength, toughness, and impact resistance. Their sturdy design guarantees long-lasting performance and dimensional stability, even under extreme temperature and pressure conditions.
