What are Stainless Steel 310S Buttweld Fittings?
Stainless Steel 310S Buttweld Fittings are components used to connect, redirect, reduce, or terminate pipe systems. Grade 310S is a low-carbon version of stainless steel 310, offering improved weldability and reduced carbide precipitation during welding.
This grade is designed for high-temperature applications, making it suitable for industries such as:
- Petrochemical plants
- Power generation
- Heat exchangers
- Furnace parts
- Oil and gas refineries
The fittings are manufactured according to A403 Stainless Steel Pipe Fittings Specification and comply with ANSI B16.9 dimensional standards to ensure compatibility in piping systems.
Key Features of Stainless Steel 310S Buttweld Fittings
- Excellent resistance to oxidation up to 1100°C (2010°F).
- High strength and toughness even at elevated temperatures.
- Good weldability due to low carbon content.
- Resistant to sulfidation and carburization.
- Long-lasting performance in aggressive environments.
