Stainless Steel 321 is a high-grade austenitic stainless steel grade that resists harsh conditions and severe exposures to chemicals. It contains a higher molybdenum content than regular 316 stainless steel and is highly resistant to acidic conditions, crevice corrosion, and pitting. Its composition offers higher strength and extends the service life of flanges in harsh applications.
SS 321 flanges have an important place in the energy production sector with steam turbines, boilers, and heat exchangers. The ability to withstand high-temperature and pressure conditions in SS 321 flanges makes them an indispensable part in efficient energy production. The marine sector also finds the anti-corrosive quality in SS 321 flanges useful in delivering long-term performance in saltwater environments.
