Hi-Tech Manufacturing, LLC -
Experts at Machining Duplex Stainless Steel
Hi-Tech Manufacturing and its subsidiary Global Contract Manufacturing (GCM) have extensive experience and expertise in machining duplex stainless steels.
From small to large components, prototype runs to long run production orders, we have the experience to manufacture duplex stainless steel components to your exact requirements.
Duplex stainless steels combine many of the beneficial properties of ferritic and austenitic materials to provide high strength and good corrosion resistance. Due to their duplex structure and high chromium, molybdenum, and nitrogen content, these steels offer many benefits in comparison to 300-series austenitic grades. Duplex stainless steels offer high strength (roughly twice that of austenitic steels), excellent resistance to stress-corrosion cracking, good resistance to pitting, crevice corrosion, erosion, and fatigue, good weldability, and heat transfer. In addition to these advantageous properties, its lower nickel content compared with austenitic grades results in greater price stability.
Due to their high strength and corrosion resistance, duplex stainless steels are used in the oil and gas, mining, food, nuclear, biofuel and other industries. Components fabricated using duplex stainless steels include rotors, impellers, shafts, pressure vessels, reactor tanks, and heat exchangers. Other applications include water transmission pipes, desalination plants and seawater systems, and stock washers and other equipment for the pulp and paper industry and biofuel plants.
