316L stainless steel bright pipe introduction
316L stainless steel bright pipe is made by cold rolling or cold drawing process, and through bright annealing treatment of stainless steel pipe. It has smooth surface, high finish, good corrosion resistance and mechanical properties, and is widely used in high-demand industrial fields.
Standard
The production and inspection of 316L stainless steel bright pipes usually follow the following international standards:
- ASTM A312/A312M: Austenitic Stainless Steel Seamless and Welded steel pipe standard.
- ASTM A269/A269M: Universal Standard for seamless and welded Austenitic stainless steel pipes.
- GB/T 12771: China standard for welded stainless steel pipes.
- JIS G3446: Japanese industry standard, stainless steel piping standard.
specification
- Outer diameter range: usually Φ6mm - Φ325mm.
- Wall thickness range: 0.5mm-12mm.
- Length: Generally 6 meters, can also be customized according to demand.
Surface treatment:
- Bright annealing (BA) : Smooth, bright surface, suitable for high cleanliness requirements.
- Polishing treatment: Different finishes can be provided according to demand (such as 180#, 240#, 320#, etc.).
- Common shapes: round, square, rectangle, etc.
316L stainless steel bright tube features
- Excellent corrosion resistance:Due to the content of 2-3% molybdenum, 316L stainless steel has stronger corrosion resistance in chloride environments (such as seawater, chemical media).
- Low carbon content:The carbon content is less than 0.03%, which reduces the carbide precipitation in the welding process and improves the resistance to intergranular corrosion.
- High finish:Bright annealing treatment makes the surface smooth, no oxidation skin, suitable for high cleanliness requirements.
- Good mechanical properties:High strength, high toughness, suitable for high load and complex working conditions.
- High temperature resistance:It maintains good mechanical properties and corrosion resistance at high temperatures.
Comparison of 316L stainless steel bright tube and 304 stainless steel tube
Features 316L stainless steel bright tube 304 stainless steel tube
Chemical composition 16-18% Cr, 10-14% Ni, 2-3% Mo 18-20% Cr, 8-10.5% Ni
Excellent corrosion resistance, especially good resistance to chloride corrosion, but poor in chloride environments
Mechanical properties High strength, high toughness strength slightly less than 316L
Excellent high temperature resistance
Surface finish bright annealed, smooth surface can be polished or brushed according to demand
The cost is higher and lower
Application fields Chemical industry, Marine, medical equipment, food industry, building decoration, home, general industry
Application field
- Chemical Industry:Used for conveying corrosive media, such as acid, alkali, salt solution, etc.
- Marine Engineering:Used in seawater desalination equipment, ship pipelines, etc.
- Medical equipment:For the manufacture of surgical instruments, implants and other high cleanliness equipment.
- Food Industry:Used for conveying high purity liquid, such as milk, juice, etc.
- Semiconductor industry:For high cleanliness gas and liquid delivery systems.
316L stainless steel bright pipe: with excellent corrosion resistance, high finish and good mechanical properties, suitable for high-demand industrial fields, such as chemical industry, Marine engineering, medical equipment and so on.
304 stainless steel pipe: Lower cost, suitable for general decoration and industrial use, but not as good as 316L in highly corrosive environments.
