Stainless steel (SS) pipe fittings are available in various grades, each designed for specific service conditions based on strength, corrosion resistance, and temperature tolerance. Common grades include SS 304, widely used in food processing, water supply, and general industrial applications due to its good corrosion resistance and affordability. SS 316 and SS 316L contain molybdenum, offering superior resistance to chemicals and chlorides, making them ideal for chemical plants, marine environments, and pharmaceuticals. SS 310 is preferred for high-temperature applications such as furnaces and heat exchangers. SS 321 is stabilized with titanium and is used where resistance to intergranular corrosion at elevated temperatures is required, such as in aerospace and exhaust systems. Choosing the right grade ensures durability, safety, and long service life in the intended application.
