Duplex UNS S31803, commonly known as Duplex 2205, is a duplex stainless steel grade renowned for its excellent mechanical properties and superior corrosion resistance. Pipe fittings made from this material benefit from its high strength, toughness, and resistance to stress corrosion cracking, making them ideal for demanding applications across various industries. Their superior performance in harsh environments and their cost-effectiveness due to reduced material thickness requirements make them a preferred choice in industries such as oil and gas, chemical processing, marine, and power generation.
A technical equivalent refers to fittings that conform to the same specifications and standards as another specified fitting but are classified differently depending on regional or international standards. Duplex UNS S31803 buttweld fittings have equivalents such as EN 1.4462, ASTM A815, and DIN 1.4462. These equivalents ensure that fittings sourced from various suppliers or regions can be used interchangeably, maintaining consistent quality, properties, and performance. This flexibility is essential for global industries, allowing for reliable sourcing and adherence to stringent engineering requirements.
The key properties of Duplex UNS S31803 pipe fittings include high strength, nearly twice that of austenitic stainless steels, and excellent corrosion resistance, particularly against pitting and stress corrosion cracking. They maintain good toughness even at low temperatures and are highly weldable. These properties offer significant benefits such as increased durability, reduced maintenance, and cost-effectiveness due to the ability to use thinner sections, making them an advantageous choice for demanding environments.
