ASTM A276 316L UNS S31600 Stainless Steel Round Bar For Industry
ASTM A276 316L UNS S31600 Stainless Steel Round Bar For Industry
Overview
The ASTM A276 316L Stainless Steel Round Bar is a low-carbon version of 316 stainless steel, widely used in applications requiring excellent corrosion resistance, high strength, and durability. It conforms to the ASTM A276 standard, which specifies requirements for stainless bars and shapes for various structural and mechanical applications.
316L stainless steel is classified under the UNS designation S31600 and is known for its ability to resist corrosion in harsh environments, including marine, chemical, and industrial atmospheres.
Key Features
- Corrosion Resistance: Exceptional resistance to chloride ions, reducing the risk of pitting and crevice corrosion.
- Low Carbon Content: The "L" in 316L stands for low carbon (<0.03%), reducing the risk of carbide precipitation during welding and enhancing intergranular corrosion resistance.
- High Strength and Durability: Excellent mechanical properties make it suitable for demanding structural applications.
- Non-Magnetic: Maintains non-magnetic properties in annealed conditions.
- Versatile Applications: Suitable for high-temperature and cryogenic environments.
