Duplex Steel S31803 Flanges

It is well known for manufacturing, supplying, and stocking all types of steel flanges in all over the world. Mehta Metals offers many different types of steel flanges. The flanges made of stainless steel are widely used since it is a highly durable and low-cost alloy. They are widely used because they have properties that make them an unbeatable quality material.

The Duplex Steel Flange has a microstructure consisting of a mixture of Ferrite and Austenite phases which makes it extremely corrosion-resistant. Due to its high strength, high corrosion resistance, and excellent intergranular corrosion, these flanges combine the properties of ferritic and austenitic stainless steel. Despite corrosion cracking stress in environments containing sulfides and chlorides, it is exceptionally resistant.

Duplex Flanges are immune to corrosion even at temperatures greater than 300 degrees Celsius. Their ductility is excellent in low temperatures as well. Fabrication is done exclusively with tools assigned for stainless steel materials. 

It is necessary to clean them properly before they are used. This saves the stainless

In order to harden them, heat must be applied. Off-shore oil drilling companies are the main industries that utilize Duplex Steel Flanges. These flanges are used for aviation exhaust manifolds, petrochemicals, power generation, gas processing, pharmaceuticals, special chemical applications, spiral welded tubes for burner pipes and fuels, pharmaceutical equipment, heat exchangers, and seawater equipment. There are many types of double steel flanges available, including slip-ons, weld-necks, blinds, threaded, lap joints, and socket welds.

It is certified to EN 10204/31B. Intergranular corrosion (IGC) tests, flare tests, pitting resistance tests, micro, macro, flattening tests, positive material identification tests, chemical analyses, hardness tests, and mechanical tests such as tensile of area are all examples of material testing. During shipment, the material is packaged on wooden pallets and cases to protect it from damage and to maintain the customers' trust.
