Product Details
316 2B stainless steel is a widely used austenitic stainless steel sheet with a 2B cold rolled finish. It combines the excellent corrosion resistance of 316 stainless steel with a smooth, matte surface that is suitable for industrial processing and fabrication.
What is 316 2B Stainless Steel?
316 stainless steel is enhanced with molybdenum (Mo), which significantly improves resistance to pitting, chloride corrosion, and harsh chemical environments. The 2B finish refers to a cold rolled surface that is smooth, uniform, and slightly reflective, making it the most common industrial surface condition.
Key characteristics:
- Austenitic stainless steel (non-magnetic in annealed condition)
- Excellent corrosion resistance (especially against chlorides)
- Smooth 2B mill finish surface
- Good formability and weldability
Common Applications of 316 2B Stainless Steel
316 2B stainless steel is widely used in environments requiring high corrosion resistance and hygienic performance.
