Duplex and Super Duplex washers are engineered for superior corrosion resistance, making them ideal for demanding environments such as offshore oil rigs, chemical processing plants, and marine applications. Their duplex structure enhances strength and durability, while their resistance to pitting, crevice corrosion, and stress corrosion cracking ensures longevity in harsh conditions. These washers are widely used in critical bolting applications where corrosion protection is paramount.

Sumit Impex ensures the quality and performance of Duplex and Super Duplex washers through rigorous testing. Micro and macro tests assess structural integrity while flaring tests gauge ductility. Pitting resistance tests evaluate corrosion resistance, which is crucial for harsh environments. Positive Material Identification (PMI) testing also confirms chemical composition adherence to standards. These tests collectively guarantee the reliability and suitability of Duplex and Super Duplex washers offered for industrial applications.
