Duplex Steel Pipe Fittings Manufacturer in India - UNS S31803 / S32205 Offering Superior Pitting & Crevice Corrosion Resistance, High Strength and Long Service Life
Metalica Forging Inc is a Duplex Steel Pipe Fittings Manufacturer having high quality fittings which use duplex grades include UNS S31803 and S32205. The fittings have the properties of ferritic steel strength, and characteristics of austenitic alloys due to which it can be used in highly corrosive and high-stress situations. They are designed in a shape of elbow or tees, reducers and flanges and offer excellent mechanical characteristics as well as good resistant to pitting, crevice and cracking of stress corrosions. Examples of common applications are chemical processing, oil & gas pipelines, desalination plant, structural construction, and marine. Discover our high-performance Monel Pipe Fittings for reliable piping solutions.
Material Behavior & Performance Insights
Duplex steels are made that are about 22-25 percent chromium, 5-7 percent nickel, and have more molybdenum + nitrogen, so that they give:
- Very high yield strength (300 times higher than the 300-series stainless)
- Exceptional chloride stress corrosion cracking data.
- Good crevice & pitting corrosion resistance (high PREN values)
- Increased fatigue strength when loading cyclically.
- Holding + welding Balancing ductile regularity.
