Chemical processing plants often deal with a combination of high pressures, high temperatures, and aggressive chemicals like phosphoric and organic acids. SRG Fasteners provides Duplex 2205 and Super Duplex 2507 hardware designed to outperform standard 300-series stainless steels.
The dual-phase microstructure of Duplex alloys provides twice the design strength of SS 316, allowing for thinner, lighter, and more cost-effective fastening solutions without compromising safety. Our fasteners are widely used in chemical tankers, heat exchangers, and flue gas desulfurization units.
Every batch of our Duplex hardware undergoes rigorous ferrite testing and corrosion rate analysis to ensure it meets the highest international benchmarks for the chemical industry.
Why choose Super Duplex over SS 316 for chemical plants?
Super Duplex offers significantly higher PREN (Pitting Resistance Equivalent Number) and nearly double the yield strength of SS 316, making it ideal for high-pressure, highly corrosive zones.
Do you provide MTC for Duplex fasteners?
Yes, all our Duplex and Super Duplex products come with comprehensive 3.1 Mill Test Certificates and NABL-approved lab reports.
