Alloyed and high alloyed steel
Stainless Steel : Unit weight from 20 kg to 4500 kg
Duplex & Superduplex : Unit weight from 20 kg to 4500 kg
As per ISO, EN, ASTM, ASME, DIN.
Duplex steels are more resistant than the austenitic steels, they are magnetic and can be weld; their corrosion resistance is better, particularly their resistance to corrosion cracking.
The duplex steels are the best choice in various industries :
OIL & GAS (offshore / onshore), CHEMICAL & PETRO-CHEMICAL, CONTROL OF POLLUTION (desulfurization, wastewater treatment), SHIPBUILDING (propulsion of ships, equipment for transportation of chemicals), PULP & PAPER, HYDRAULIC, DESALINATION OF SEA WATER, ...
