Super Duplex Steel Fasteners
These Super Duplex Steel Fasteners, which are termed as super duplex grade stainless steels, have a microstructure comparable to that of duplex grade stainless steels. The word "duplex" refers to the fact that it has a microstructure that is a mixture of ferrite and austenite in equal proportions. Compared to typical stainless steel grades, the two-phase microstructure ensures greater resistance to pitting, stress, cracking, and corrosion than the conventional stainless steel grades. The offered Super Duplex Steel Fasteners are particularly beneficial in offshore oil and gas industries and in wells where brine levels are naturally high or brine has been pumped into wells to improve recovery.
