Home > Pipe Fittings > Stainless Steel 348 Pipe Fittings
Stainless steel 348 pipe fittings provide excellent resistance to oxidation and corrosion, especially at high temperatures. Strength and strength are retained up to 870°C (1600°F) and intergranular corrosion is resisted due to columbium stabilization. This makes them ideal for high temperature applications such as aerospace, chemical processing and energy generation. The fittings also exhibit excellent weldability and formability, ensuring reliable performance and durability. Its durability reduces the need for maintenance and ensures longer durability in harsh conditions and environments.

Stainless Steel 348 Pipe Fittings are made from an austenitic stainless steel alloy containing approximately 19–21% chromium, 32–35% nickel, and controlled carbon content for enhanced high-temperature strength. This composition provides excellent resistance to oxidation, thermal fatigue, and stress corrosion cracking at temperatures up to 1100°C. The fittings typically exhibit tensile strength between 520–650 MPa and hardness around 160–190 HB. Their austenitic structure ensures superior toughness, dimensional stability, and mechanical reliability under continuous high-temperature and corrosive conditions.
