An ASTM A182 F53 Strainer is a filtration device made from super duplex stainless steel, which equates to UNS S32750. This material is often promoted by Sandvik as SAF2507 and is known for its 25% chromium content, offering improved pitting corrosion resistance compared to F51. The primary role of a strainer is to remove solid particles and impurities from fluid streams within industrial settings, thereby protecting downstream equipment and ensuring the integrity of the system.
