Manufacturer, Supplier & Exporter of Stainless Steel 310 / 310S Ferrule Fittings

Stainless Steel 310 / 310S Ferrule Fittings are designed for use in high-temperature and high-corrosion environments. These grades, particularly known for their excellent resistance to oxidation and scaling up to 1100°C, are ideal for heat exchangers, furnaces, and equipment exposed to extreme thermal conditions. SS 310 has higher carbon content than 310S, providing slightly better high-temperature strength, while 310S offers superior weldability and reduced risk of sensitization due to its low carbon composition. Both grades are widely used in industries where robust performance under thermal cycling is critical.
