Duplex Stainless Steel Manufacturer
Duplex stainless steel is a type of stainless steel that has a two-phase microstructure consisting of both austenitic and ferritic phases in equal proportions. This unique microstructure gives duplex stainless steel excellent mechanical and corrosion-resistant properties.
At Om Steel, we offer a wide range of duplex stainless steel products in various grades, shapes, and sizes to cater to our customers’ diverse needs. Our duplex stainless steel products are highly durable, versatile, and corrosion-resistant, making them ideal for use in harsh environments such as offshore oil rigs, chemical processing plants, and marine applications.
One of the significant benefits of duplex stainless steel is its high strength, which allows it to withstand high-pressure and high-stress environments. Duplex stainless steel also has excellent corrosion resistance properties, making it ideal for use in corrosive environments, including acidic and chloride-containing environments.
Duplex stainless steel is easy to fabricate, weld, and machine, making it an attractive option for a wide range of applications. At Om Steel, we ensure that our duplex stainless steel products are of the highest quality, and our team of experts works tirelessly to meet our customers’ specifications and requirements.
Properties of Duplex Stainless steel
High strength
Duplex steel has higher strength than conventional austenitic stainless steel, which allows it to be used in applications where high strength is required.
Corrosion resistance
Weldability
Duplex steel is generally considered to be highly weldable, although care must be taken to avoid certain welding defects that can occur.
