Product Description:
316 and 316L stainless steel forged fittings are high-performance components specifically designed for applications requiring superior corrosion resistance, high strength, and durability. These fittings are ideal for industries where chemical exposure, high temperatures, and environmental challenges are prevalent.
316 Stainless Steel
- Known for its excellent corrosion resistance due to molybdenum content.
- High strength and durability in both low and high-temperature applications.
- Suitable for environments with chlorides and industrial solvents.
316L Stainless Steel
- A low-carbon version of 316, designed to minimize carbide precipitation during welding.
- Offers enhanced weldability and corrosion resistance, particularly in highly corrosive environments.
- Ideal for applications requiring frequent welding or exposure to corrosive agents.
Key Features of 316/316L Stainless Steel Forged Fittings
- Superior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking.
- High-Temperature Performance: Retains mechanical properties in environments up to 870°C.
- Exceptional Strength: Provides excellent tensile and yield strength for demanding applications.
- Non-Magnetic: In the annealed condition, these fittings are non-magnetic.
- Ease of Fabrication: Easily machined, welded, and fabricated for custom requirements.
Common Applications
- Chemical Processing: Pipes and fittings for handling acidic and chloride-rich solutions.
