Product Description
F53 (also known as 2507) Super Duplex is an austeniticferritic (duplex) stainless steel. Consisting of 25% Chromium and 7% Ni. F53 (2507) super duplex, like other duplex grades combines higher corrosion resistance and strength compared to other austenitic stainless steels, while also having superior pitting resistance. F53 boasts higher impact strengths over F51, It is also suitable in applications in environments of -50°F to +600°F temperature range. Like other duplex grades F53 does suffer from embrittlementand loss of toughness, when exposed to prolonged use in applications or environments below -50°F or above +600°F, this is why duplex is not suitable for exposure outside of these ranges.
    Super duplex blind flange is a type of flange, specifically a solid, circular plate with no bore, designed to seal off the end of a piping system or pressure vessel opening. It's made from super duplex stainless steel, which offers high strength and excellent corrosion resistance, making it suitable for demanding applications.
