Duplex stainless steel S32760 Zeron 100 thread rod

A789 UNS S31803 and UNS S32205 are two grades of duplex stainless steel that are widely used in various industrial applications. These Duplex S31803 Seamless Pipes are known for their excellent corrosion resistance, high strength, and good weldability. A789 is a specification that covers seamless and welded tubes made from duplex stainless steel.

It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.

Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities to austenitic and duplex stainless steels in virtually all corrosive media, and critical pitting temperature Above 50¡ãC .

ASTM A240 Type 2205 Plate is a duplex stainless steel plate that is used extensively in various industries such as chemical processing, oil and gas exploration, and marine engineering. SA 240 GR 2205 Sheet is made from grade 2205 stainless steel, which is a combination of ferritic and austenitic steel.

The duplex steels are one type of stainless steels that have ferritic and austenitic phases in their metallurgic microstructure.

Duplex stainless steels are Fe-Ni-Cr alloys consisting of ferritic-austenitic microstructure at room temperature. These steels generally possess beneficial combinations of the austenitic and ferritic phases. Duplex stainless steels exhibit greater toughness and better weldability than ferritic stainless steel (Nilsson, 1992). They have higher strength and better corrosion resistance than austenitic stainless steel (Atamert and King, 1992). Their good engineering performance has led to an increasing number of applications, mainly in corrosive environments such as sour gas pipelines and chemical reaction vessels.
Duplex stainless steels combine characteristics of the austenitic and ferritic family of alloys to offer benefits from both with fewer downsides — often at a lower cost than other steel alloys.
Duplex stainless steels have a combination of two phases, ferrite and austenite in approximately equal measure. This allows them to benefit from the advantages of both austenitic and ferritic stainless steels, leading to increased strength, improved weldability, higher toughness and resistance to several types of corrosion.

Duplex 2205 flanges combine the qualities of stress corrosion cracking resistance and high strength derived from being a ferritic alloy along with its austenitic fabrication capabilities.

ASTM A182 F53 flanges refer to flanges made from super duplex stainless steel 2507 (UNS S32750) by a hot forging process.

Duplex 2205 stainless steel plate has excellent corrosion resistance, much higher than grade 316. It can withstand localized corrosion types such as intergranular, pitting and crevice.

Super Duplex UNS S32760 is one of the most common super duplex grades on the market. UNS S32760 is a duplex stainless steel designed for use in corrosive chlorine-containing environments, with the addition of W and Cu compared to UNS S32750.

Super Duplex UNS S32750 is the most common Super Duplex grade on the market. UNS S32750 is a duplex stainless steel designed for use in corrosive chlorine-containing environments. It has very good localized corrosion and stress corrosion cracking resistance and high mechanical strength. Widely used in oil and gas, hydropower, pressure vessels, pulp and paper, structural parts and chemical tankers.

2507 is also used in Flue Gas Scrubbing Equipment, Pulp and Paper Mill Equipment, Offshore Oil production/technology and Oil and gas industry equipment.

The notch ductility of SA 240 S32760 Sheet performs well at sub-zero temperatures, down to the -50¡ãC range, while performing well at ambient temperature.

Super Duplex 2507 Lock Washers has excellent corrosion resistance in marine environments.Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.

The microstructure and composition of the duplex 2205 alloy provides corrosion resistance superior to Type 316 or 317 in many environments, and its minimum yield strength is more than double that of conventional austenitic stainless steels.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy.

Stainless steel grade UNS S31803 is highly resistant to intergranular corrosion due to its low carbon content, which prevents carbide precipitation at grain boundaries.

It is also exceptionally resistance to chloride SCC. Flanges are supplied with pitting resistance equivalent that is assuring very good pitting corrosion resistance.

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

The applications of the flanges include petroleum, petrochemical, oil and gas and other high performing piping systems.

Debido al peso ligero de la tuberia soldada ASME SA790 de acero duplex UNS S32205, se utiliza en procesos de ingenieria aeroespacial y nuclear. Tambien se utiliza en la industria automotriz y de la construccion debido a su alta resistencia al desgaste y capacidad para trabajar en ambientes de alta tension.

Super Duplex Stainless Steel is known to have better stress corrosion, cracking resistance and mechanical properties than any other type of steel.

ASTM A1082 specification alloy S31803 fasteners have higher pitting and crevice corrosion than stainless steel alloy 316. Due to its higher corrosion resistance, alloy grade UNS S31803 is able to exhibit better fatigue strength than other commonly used austenitic stainless steel grades in environments containing corrosive media.

Alloy 2205 duplex stainless steel plate has better pitting and crevice corrosion resistance than 316L or 317L austenitic stainless steel in almost all corrosive media.

The combination of high strength, corrosion resistance and moderate weldability has many benefits but also bring disadvantages and limitations. High strength is a disadvantage when forming and machining. The higher strength also means that the metal is less ductile than austenitic grades. This means that these steels are not good when the goods being produce require any degree of complex forming. It is also worth bering in mind that evemn if the item can be formed in duplex steel greater forces are required. The metallurgy of duplex stainless steels is much more complex than for austenitic or ferritic steels whith the result that they are more complex and therefore expensive to produce. Howver the lower quantity of nickel in them as compared to austenitic grades does help to keep the cost down and reduce price volatility.
