Product Description:
316 and 316L stainless steel round bars and rods are premium austenitic stainless steels known for their superior corrosion resistance, durability, and strength. Enhanced with molybdenum, these grades outperform 304 stainless steel in harsher environments, particularly in marine, chemical, and high-temperature applications.
316 Stainless Steel
- Contains molybdenum, enhancing corrosion resistance, particularly against chlorides and acidic environments.
- Excellent mechanical properties and toughness.
316L Stainless Steel
- A low-carbon version of 316 stainless steel, providing improved weldability and minimizing the risk of carbide precipitation during welding.
- Ideal for applications requiring corrosion resistance and durability in challenging conditions.
Key Features of 316/316L Stainless Steel Bars and Rods
- Superior Corrosion Resistance: Excellent resistance to chlorides, brines, and chemicals.
- High Strength: Exceptional tensile and yield strength for demanding applications.
- Good Weldability: Suitable for welding without post-weld annealing in most conditions.
- Non-Magnetic: Non-magnetic in the annealed condition, though slight magnetism may develop after cold working.
- Heat Resistance: Performs well in elevated temperature environments up to 870°C (intermittent) and 925°C (continuous).
Common Applications
- Marine Industry: Boat fittings, shafts, and fasteners exposed to saltwater.
- Chemical Processing: Tanks, valves, and heat exchangers handling corrosive substances.
- Pharmaceutical Equipment: Equipment used in sterile and hygienic conditions.
- Food and Beverage Industry: Production and storage equipment for acidic and salty products.
- Oil and Gas Industry: Piping, valves, and other components in offshore and harsh environments.
