What is Stainless Steel 316 Round Bar?
Stainless Steel 316 Round Bar is a molybdenum-bearing austenitic stainless steel rods and bars that provides excellent resistance to corrosion, especially in chloride and marine environments. Compared to SS 304, Grade 316 offers improved performance against pitting, crevice corrosion, and chemical attack.
This grade is commonly supplied as:
- SS 316 Round Bar
- SS 316 Hex Bar
- Stainless Steel 316 Square Bar in India
- A479 Gr 316 Flat Bar
- SUS 316 Rectangular Bar
- UNS S31600 Forged Bars
- Stainless Steel Werkstoff Nr. 1.4435 Threaded Round Bars
Key Benefits of Stainless Steel 316 Rod
- Excellent corrosion resistance in aggressive environments
- Superior resistance to chlorides and saltwater
- High tensile and yield strength
- Good weldability and machinability
- Performs well at high and low temperatures
- Hygienic and easy to clean for food and pharma use
This is why AISI 316 Round Bar, 1.4401 Round Bar, and UNS S31600 Stainless Steel Round Bar are widely specified in international standards.
