What are Stainless Steel 6MO Buttweld Fittings?
Stainless Steel 6MO Buttweld Fittings are piping components made from the SMO 254 (UNS S31254) grade of stainless steel, which contains high levels of molybdenum (around 6%). This composition provides:
- Excellent resistance to pitting and crevice corrosion
- High chloride stress corrosion cracking resistance
- Outstanding durability in seawater and other chloride-rich environments
These fittings are installed by welding, which ensures a permanent, leak-proof, and strong connection in piping systems.
Key Features of Stainless Steel 6MO Buttweld Fittings
- High Molybdenum Content – Provides excellent resistance to pitting & crevice corrosion
- Chloride Resistance – Withstands aggressive chloride-containing environments like seawater
- Strength & Durability – High mechanical properties make them suitable for high-pressure systems
- Weldability – Easy to fabricate, weld, and install in various systems
- Cost-Effective – Long service life reduces maintenance and replacement costs
