MD Exports LLP produces duplex fasteners in all grades of duplex, to customer specification. Duplex grades are a mixed microstructure of Austenite and Ferrite, combining the properties of both (hence the name DUPLEX). Duplex stainless steels have high corrosion resistance as well as a high strength. Mechanical properties are around double that of a typical austenitic grade such as 316. They would also normally offer higher stress cracking resistance in Chloride solutions for example. They are composed typically of 22% Chromium, 5 % nickel. Having worked with duplex since its outset, the duplex bolting continues to account for a core part of our business, along with Super duplex.

We are proud that MD Exports LLP is the world’s number Ten bespoke producer of Super Duplex bolting. Super Duplex stainless steel grades are similar to standard duplex, but they contain a higher content of Chromium, thus enhancing the corrosion resistance and mechanical properties. MD Exports LLP produces fasteners in all three types of Super Duplex.
