What is Stainless Steel 317L?
Stainless Steel 317l is a low-carbon version of grade 317 stainless steel. It contains a higher amount of molybdenum, chromium, and nickel, which gives it great corrosion resistance compared to standard stainless steels like 304 or 316. The “L” in 317L stands for Low Carbon, making it highly weldable and less prone to sensitization during welding.
This makes SS 317L Pipe Fittings perfect for use in environments where strong resistance to chemical attack and high temperatures is needed.
Advantages of Using Stainless Steel 317l Buttweld Fittings
- Corrosion Resistance: Excellent performance in acidic and chloride-containing environments.
- Weldability: Low carbon content prevents carbide precipitation during welding.
- High Strength: Handles high temperatures and pressures without deformation.
- Durability: Longer service life with reduced maintenance needs.
- Compliance: Meets international standards like ASTM A403, DIN 1.4438, and ASME SA403.
