GENERAL PROPERTIES

316/316L stainless steel alloy is a high-performance austenitic stainless steel pipe enriched with molybdenum. This grade's enhanced nickel and molybdenum content significantly bolsters its overall corrosion resistance beyond that of 304, especially in combating pitting and crevice corrosion in chloride-rich environments. Moreover, 316/316L seamless pipes offer outstanding high-temperature tensile strength, creep resistance, and stress-rupture strength. They also exhibit superior formability and weldability. The 316L variant, with its low carbon content, resists sensitization, making it ideal for large size welded components.

Specifications: UNS S31600/S31603.

APPLICATIONS:

Thanks to its myriad advantages, 316 Stainless Steel tubes are employed across diverse applications and environments, including but not limited to the following:

• - Food preparation surfaces, equipment, and appliances, particularly in chloride environments
• - Laboratory benches & equipment

• - Industrial equipment for handling corrosive process chemicals in the production of inks, textiles, bleaches, photographic chemicals, and rubber
• - Food preparation equipment, especially in chloride environments
• - Architectural applications
• - Medical implants, including pins, screws, and orthopedic implants like total hip and knee replacements

• Food preparation equipment, particularly in chloride environments
• Chemical processing equipment
• Laboratory benches and equipment
• Rubber, plastics, pulp & paper machinery
• Pollution control equipment
• Boat fittings, valve and pump trim
• Heat exchangers
• Pharmaceutical and textile industries
• Condensers, evaporators, and tanks

STANDARDS:

• ASTM/ASME: UNS S31600 / S31603
• EURONORM: X1 CrNiMo 17 12 2 / X3 CrNiMo 17 12 2
• AFNOR: Z 6 CND 17-11 / Z 2 CND 17-12
• DIN : 1.4401 / 1.4404

CORROSION RESISTANCE:

• 316 stainless steel offers superior corrosion resistance compared to 304, thanks to its elevated levels of chromium and molybdenum.
  These elements enhance its durability in a variety of corrosive environments.
• It remains susceptible to pitting and crevice corrosion in warm chloride settings, and stress corrosion cracking above 122°F (50°C).
• 316 stainless steel is considered potable water-resistant with chloride levels up to 1000mg/L at ambient temperatures, reducing to 500mg/L at
  140°F (60°C).
• Often referred to as marine grade stainless steel, 316 is generally corrosion-resistant but not suitable for warm seawater environments.

HEAT RESISTANCE:

• 316 stainless steel exhibits excellent oxidation resistance, tolerating intermittent service up to 1600°F (870°C) and continuous service up to 1700°F (925°C).
• Grade 316L, with its lower carbon content, is more resistant to carbide precipitation.

WELDING CHARACTERISTICS:

• 316 stainless steel can be welded by all standard fusion methods, with or without filler metals, offering exceptional weldability.
• For maximum corrosion resistance, heavy welded sections of Grade 316 should undergo post-weld annealing, though this is not necessary for 316L.

HEAT TREATMENT:

• The annealing temperature range for 316 stainless steel is between 1900°F to 2100°F (1038°C to 1149°C).
• This grade cannot be hardened by heat treatment.
• Special considerations must be made for its high thermal expansion coefficient to prevent warping and distortion during heat treatment.

PROCESSING - HOT FORMING:

• Most producers recommend forging within a maximum temperature range of 2100°F to 2300°F.
• Do not forge below 1700°F (927°C).
• Optimal corrosion resistance is achieved when the forged pieces receive a final annealing process.

PROCESSING - COLD FORMING:

• 316/316L stainless steel types are extremely tough and ductile, making them ideal for various cold working processes such as roll forming, swaging, cold heading, deep drawing,
  and bending with ease.
• Severely cold-formed parts should be annealed to alleviate stress.

MACHINABILITY:

• 316/316L stainless steel is more challenging to machine compared to 304 due to its toughness.
• It produces tough and strong chip characteristics.
• Using chip breakers and curlers is recommended.
• Employ large tools and substantial cutting fluid for best results.
• Consider heavy positive feeds at low speeds to counteract rapid work hardening.
