Stainless Steel Grade 316 is the 'marine grade' standard for the fastener industry. At SRG Fasteners, we manufacture a comprehensive range of SS 316 bolts, nuts, washers, and specialized fittings that provide superior resistance to pitting and crevice corrosion in chloride environments.
Our SS 316 fasteners are produced using high-quality raw materials sourced from trusted mills, ensuring that every batch meets the strict mechanical and chemical properties required by international standards such as ASTM A193/A194 and DIN/ISO.
Whether you are working on offshore oil rigs, pharmaceutical cleanrooms, or coastal infrastructure projects, our SS 316 hardware ensures longevity, safety, and zero-maintenance performance in the most demanding conditions.
Why is SS 316 better than SS 304 for marine use?
SS 316 contains 2-3% Molybdenum, which provides significantly better resistance to salt-water corrosion and pitting compared to SS 304.
Do you provide test certificates for SS 316 fasteners?
Yes, we provide 3.1 Mill Test Certificates (MTC) and NABL-approved lab reports with every batch to ensure full traceability.
