Premium Material: 316 Stainless Steel
316 stainless steel represents the superior grade in the austenitic stainless steel family, characterized by:
Enhanced corrosion resistance due to 2-3% molybdenum content
Excellent resistance to pitting and crevice corrosion in chloride environments
High tensile strength (515 MPa min) and yield strength (205 MPa min)
Good elevated temperature strength and oxidation resistance
Superior formability and weldability compared to standard stainless grades
The alloy's chemical composition typically includes 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, creating an optimal balance between mechanical properties and corrosion resistance for severe service conditions.
