Peeled Round Bars / Stainless Steel
AISI 316
Molybdenum-bearing Stainless Steel
Material Overview
AISI 316 - Molybdenum-bearing Stainless Steel
Material Type
Type: Austenitic with molybdenum addition
Key Benefit: Superior pitting and crevice corrosion resistance
Corrosion Resistance
Exceptional Performance: Superior pitting and crevice corrosion resistance in chlorides (sea water, chemicals, de-icing salts). Molybdenum content provides enhanced resistance to reducing acids and chloride-ion solutions.
Mechanical Properties
| Tensile Strength: | 515-750 MPa |
| Yield Strength: | 205-310 MPa |
| Hardness: | ~200 HB |
| Creep Strength: | High at elevated temperatures |
Applications
- Marine shafts and hardware (coastal/offshore)
