SS316/316L flanges offer excellent corrosion resistance, improved resistance to pitting and crevice corrosion, good mechanical strength, excellent toughness, good weldability and long service life. The addition of molybdenum provides enhanced resistance to localized corrosion compared with 304 stainless steel in many environments. SS316L, with its lower carbon content, is particularly suitable for welded piping and fabricated process equipment.
SS316/316L flanges are widely used in oil & gas, petrochemical, chemical processing, pharmaceutical, food & beverage, marine, offshore, water treatment, power generation, pulp & paper, textile, mining and general process industries. Typical applications include process piping, pressure vessels, heat exchangers, pumps, valves, storage tanks and equipment connections.
The raw materials for Stainless Steel 316 and 316L flanges are sourced from certified suppliers and undergo rigorous inspection. Each batch is tested for chemical composition through Positive Material Identification (PMI) to ensure compliance with ASTM A182 and ASTM A240 standards. Materials are verified for their mechanical properties, including tensile strength and yield strength, prior to fabrication.
Stainless Steel 316 and 316L flanges are formed through processes such as forging, machining, and welding as per ASME B16.5 and B16.47 standards. The flanges are available in various sizes ranging from 1/2" to 24" in diameter, with pressure ratings of Class 150, 300, 600, and 900. Each flange is fabricated to meet precise dimensions and tolerances, ensuring a perfect fit for piping systems.
| Process | Temperature (°C) | Medium | Purpose |
|---|---|---|---|
| Solution Annealing | 1040-1100 | Air | To dissolve carbides and enhance corrosion resistance |
| Stress Relieving | 300-400 | Air | To relieve internal stresses generated during fabrication |
