What is Duplex Stainless Steel?

Duplex is a type of stainless steel that combines austenitic and ferritic properties. The austenitic lattice provides tensile strength and ductility, whereas the ferritic phase provides strength. Due to their two-phase structure, duplex stainless steels have high yield strength. In actuality, duplex grades of stainless steel are nearly twice as strong as austenitic ones.

Duplex Steel Forged Fittings offer remarkable resistance to both stress corrosion cracking and intergranular corrosion while still maintaining adequate ductility because of its heterogeneous structure. Duplex’s high strength and low nickel content also permit the use of thinner sections, which significantly reduces costs for the end user.

Applications of Duplex Steel Forged Fittings

Natural Gas and Petroleum

A material with excellent corrosion resistance, flexibility, and strength is required for the oil and gas industry. Duplex stainless steel satisfies all the criteria. Duplex stainless steel is particularly well-suited for offshore applications that run at high pressures and severe depths because of its strong resistance and durability to chloride stress corrosion cracking. For onshore pipes delivering corrosive substances, duplex is a common material. The oil and gas industry continues to be the biggest consumer of duplex stainless steel as a result.

Development & Building

The possibilities for architectural design are revolutionized by duplex stainless steel. Due to their distinct combination of strength and aesthetic appeal, these grades are particularly suitable for roofs, façades, and bridges.

The form freedom and aesthetic adaptability needed to blend into a variety of situations and architectural styles are provided by duplex stainless steel. Stainless steel may be used with a variety of building technologies in addition to being durable, easy to maintain, and recyclable.

Similar to automobile and pedestrian bridges, suspension bridge wires, cables, tie rods, railings, and banisters can all be made of duplex stainless steel.

Desalination and Water Treatment

A durable material that can withstand the corrosive nature of water, liquids, and salt is required for desalination and water treatment applications. What you’re seeing is duplexed stainless steel, its outstanding strength, corrosion resistance, long lifespan, and cost-effectiveness, this stainless steel has benefits that transcend the initial investment costs.

Transportation

Many aspects of society depend on a productive system for moving goods and people. Boats, airplanes, trains, and automobiles are just a few of the vehicles that use duplex stainless steel.

For instance, truck tanks and trailers made of such high-strength stainless steel enjoy unmatched efficiency, durability, and corrosion resistance. Additionally, they cost less than standard carbon steel alternatives.
