What separates the Super Duplex Steel alloy from ordinary stainless steel is, its dual characteristics nature of having austenitic and ferritic grains structure. This structure comes into use when the duplex steel alloy is melted at a very high temperature, during which the austenitic and ferritic materials switch roles and the final hardened alloy has roughly 50/50 proportion when it comes to its core structure. This dual nature gives the super duplex steel rods and super duplex steel bars enhanced strength which enables its use in very high pressure areas. The dual nature of the Super Duplex Steels is not completely hardened, and exhibits a semi-hardened nature which makes it ductile and enables the complete transformation of the alloy into a different form. Also addition of additives like chromium enhances it s resistance against pitting and other corrosive properties.
Rods and bars are forged using various lathes and dies that precisely forge using either computer guided machinery or manual hand working methods, if the result cannot be achieved by the former. The rods and bars are can handle external stress very well and do not crack, creep or deform. But certain grades of Super Duplex Steel do experience negative effects around certain harsh chemicals. The semi-hardened properties of the rods and bars make it easy to carve and forge them specifically custom as needed for the area of application.
