Duplex 2205 bolts are among the most commonly used duplex grades. These are called standard duplex steel fasteners. There are different types of fasteners such as studs, bolts, nuts, screws, etc. Duplex stainless steel fasteners are used in chemical processing, transportation, storage, oil and gas, marine, paper and pulp, wine and many other industries. A wider range of applications is possible due to the combination of corrosion resistance, high temperature capability and high pressure resistance of Duplex Steel 2205 Nuts and Bolts.

Duplex stainless steel has an array of various benefits such as:
Strength:Duplex stainless steels have approximately double the strength of regular austenitic or ferritic stainless steels.
Toughness and ductility:Duplex stainless steels exceed the toughness and ductility of ferritic grades although they are not as touch as austenitic grades.
Corrosion resistance:As with all stainless steels, corrosion resistance depends mostly on the composition of the stainless steel, with chromium, molybdenum and nitrogen content being the most important. Duplex stainless steels are extremely corrosion resistant and even in chloride and sulphide environments, duplex stainless steels exhibit very high resistance to stress corrosion cracking (SCC). SCC is a type of corrosion that takes place when a particular set of factors are present: Tensile stress, corrosive environment and a sufficiently high temperature.

2205 fasteners are widely used in applications requiring good corrosion resistance and strength. Has excellent corrosion resistance; much higher than other grades. It eliminates localized corrosion types such as intergranular corrosion, pitting corrosion and crevice corrosion. Duplex 2205 bolts are ideal for environments containing chlorides and hydrogen sulfide for oil and gas extraction from sour wells, refineries, and chloride-contaminated process solutions.

Super Duplex is used in gas and oil industry, on offshore platforms, chemical processing equipment pressure vessels and boilers, in heat exchangers.

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

The flanges could also be manufactured as screwed, threaded or forged types. The forged flanges are made from a single piece of raw material. These are also called the cast flanges.

Alloy 2205 duplex stainless steel plate is an alloy duplex stainless steel plate containing 22% chromium, 3% molybdenum, and 5-6% nickel nitrogen.

The material of the super duplex S32750 sheet has increased tensile strength and yield strength. Super Duplex Steel UNS S32750 plate has good ductility and toughness. AISI S32750 plate has good corrosion resistance compared to Duplex. The material of the super duplex steel S32750 plate has higher corrosion resistance.

The inclusion of chromium imparts good corrosion resistance to austenitic grade 304. However, increasing the chromium content to about 25%, as in the case of 2205 duplex stainless steel pipe makes the alloy resilient across several media.

2101 is a low nickel, lean duplex stainless steel possessing both superior strength and chloride stress-corrosion cracking resistance when compared to 300 series stainless steel.

These super duplex UNS S32760 round bars are available in a variety of shapes, sizes and diameters depending on the needs and requirements of the application and customer supplied specifications. These super duplex UNS S32760 round bars are resistant to localized corrosion.

The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.

Duplex 2205 stainless steel (ferritic and austenitic) is widely used in applications requiring good corrosion resistance and strength. Grade S31803 stainless steel was modified several times to form UNS S32205, which was recognized in 1996.

At this temperature, duplex steel flanges over 300 degrees Celsius are still protected from embrittlement due to corrosion. Duct capability is also excellent at low temperatures. Fabrication is done only with tools assigned to stainless steel materials. Must be properly cleaned before use. This is done to protect the stainless steel from cross-contamination of the corroding metal.

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.
