ASTM Standard Duplex Steel Hollow Bars supplier

Duplex Steel Hollow Bars are round and look like a pipe or a tube with thicker walls. Duplex Steel Hollow Bars are both hollow bars and seamless tubes. A hollow bar has the strength of a solid round bar, there is less weight per foot which saves money without compromising strength. Duplex Steels have a two-phase microstructure consisting of grains of ferritic and austenitic Duplex Steel. The word “duplex” denotes the two-phase microstructure of ferritic and austenitic steel grains. The ferritic and austenitic Duplex Steel grades have approximately equal proportions (i.e., 50% each) in Duplex Steel. The main difference between Stainless Steel and Duplex Steel is in composition i.e. they have a higher chromium content of 20–28% higher molybdenum, up to 5% lower nickel, up to 9% and 0.05–0.50% nitrogen content.

Duplex Steel are extremely corrosion resistant having high resistance to intergranular corrosion. Duplex Steel exhibits very high resistance to stress corrosion cracking even in chloride and sulphide environments. The high chromium content of Duplex Steel that protects against corrosion. At low temperatures Duplex Steels have superior ductility than the ferritic and martensitic grades and can readily be used down to at least -50 °C. Duplex Steel provides high mechanical strength and exceptional corrosion resistance properties.

ASTM Duplex Steel Hollow Bars are used in production of valves and actuators like valves, flowmeters, filters, manifolds, and in pumps and compressors like hydraulic cylinders, vacuum equipment, pump housings. ASTM Duplex Steel Hollow Bars are used in manufacturing of axes and shafts like rolls, guides, bushings, clamps, bearings, and in mechanical gaskets (seals, spacers, rings), connection components (fittings, flanges, couplings, connectors), and in measuring instruments like solenoids, sensors, resistors.
