Duplex 2205 nuts are fasteners made from Duplex 2205, a duplex stainless steel alloy known for its exceptional strength and corrosion resistance. These nuts are commonly used in marine, chemical, and petrochemical industries due to their resistance to corrosion in harsh environments. With a unique microstructure combining austenitic and ferritic phases, Duplex 2205 nuts offer superior performance in applications where strength and corrosion resistance are crucial.
At Sumit Impex, we prioritize thorough quality inspections for all materials before customer delivery. These inspections include various tests such as hardness testing, chemical analysis using spectro analysis, and positive material identification via PMI (Positive Material Identification) testing. Additionally, we conduct tests like flattening, micro and macro, pitting resistance, flaring, and intergranular corrosion to ensure product integrity. Furthermore, we offer third-party inspection certificates to ensure complete client satisfaction.
