At temperatures above 300¡ãC, the brittle trace components of 2205 precipitate, and at temperatures below -50¡ãC, the trace components undergo a ductile-brittle transition; therefore, this grade of stainless steel is not suitable for use at these temperatures.

S32760 was originally developed as a seawater resistant material for pump applications in the North Sea.

Alloy 2205 duplex stainless steel sheet is particularly suitable for applications covering the -50¡ãF/+600¡ãF temperature range.

A high molybdenum superaustenitic with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. Suitable for use in pulp mill bleach plants, seawater heat exchangers and chemical process equipment.

This heat treatment performed on the Duplex 2205 Pipe must be keeping with accordance to the specified temperature and quench conditions.

The dual phase steel / super duplex steel stainless steel pipe is a kind of stainless steel with high strength and high corrosion resistance, which has the properties of austenitic stainless steel and ferritic stainless steel. Generally, when the carbon content is low, the Cr content is 18% ~ 28%, and the Ni content is 3% ~ 10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloy elements.

While Duplex 2205 is the most common duplex product we supply, we can also deliver Duplex 2304 and Duplex 2207 with reduced lead times as these alloys are stocked. Alloy 2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel pipe with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

The A182 Gr. F51 / S31803 material is a typical duplex stainless steel, which contains approximately 50% ferrite and 50% austenite.

A Super Duplex 2507 Pipe has outstanding resistance to corrosive and oxidative media.

UNS S32205 Hex Bolts (also known as S31803) are made of high grade duplex 2205 stainless steel. Because this material is composed of at least 22% chromium, 6% nickel, and 3% molybdenum, it can withstand some of the harsh environmental conditions that other metals cannot, such as corrosion, cracking, erosion, pitting, and more. Stainless Duplex 2205 Hex Bolts also provide twice the mechanical strength compared to standard stainless steel.

Zeron 100?contains 25% chromium and 7% nickel and 3.6% molybdenum along with copper and tungsten additions. Zeron 100 has a 50¨C50 austenitic¨Cferritic structure. It also has greater resistance to chloride pitting, crevice corrosion and stress corrosion cracking than exhibited by the standard 300 series stainless steels.

2205 Duplex nuts are the most widely used duplex stainless steel 2205 fasteners and feature a high yield strength that is twice that of standard austenitic stainless grades.

2205 helps users to avoid stress corrosion cracking that is typically seen with 316 and 317.

The most widely used stainless steel alloy is duplex 2205. It is also known as Duplex 2205 or Duplex 2205. It has ferritic and austenitic properties, making it ideal for environments with strong corrosion resistance. Good strength is a primary requirement. Duplex 2205 studs are essentially just a piece of threaded rod, in some cases, they are all designed to accept nuts, such studs are called stud bolts. It has excellent corrosion resistance and is superior to stainless steel 316 in most environments.

ASTM A479 Super Duplex UNS S32750 F53 Heavy Hex Nuts are kept together by a combination of their threads’ friction (by means of slight elastic distortion), a small widening of the bolt, and solidity of the components to be held together.

Duplex variety stainless steels work well in those applications which contain a high concentration of chlorine. Chloride ions, which are normally detrimental to conventional stainless steels, do not cause any damage to the much stronger Duplex Stainless Steel Pipe. The chemistry of this steel ensures better performance with higher mechanical properties in comparison to austenitic stainless steel pipes.

The mechanical strength, corrosion resistance and low temperature toughness of the ASTM A182 F53 Flanges is higher than that of ordinary duplex stainless steels.

ASTM A240 Type 2507 Duplex Sheet is an alloy used in applications with high strength and corrosion resistance. The composition of the duplex 2507 sheet is approximately 25% chromium, 7% nickel and 4% molybdenum. This composition makes it resistant to crevice corrosion and chloride pitting.

Duplex stainless steel fasteners are made from alloys with high chromium content and low to moderate nickel content.

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.

2205 is the standard duplex grade and is more economical than most other duplex grades.

Super Duplex are trace amounts of carbon, phosphorus, sulfur, silicon, nitrogen, and copper. It has great general consumption resistance, proposed for applications up to 600¡ã F, and low rate of warm development.

The 21% chromium content is the key to extreme corrosion resistance and strength of the SA 182 f51 flanges. HT PIPE is a leading supplier and manufacturer of the flanges in various scales, shapes and types.

ASTM A479 Super Duplex UNS S32750 Fasteners is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades.

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.

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.
