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.

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 .

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

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.

Super Duplex has all the benefits of other duplex steels, specifically the strength benefits of their biphasic structural composition of equal parts austenitic and ferritic stainless steel. This microstructure makes all duplex steels around twice as strong as regular single structure ferritic or austenitic steels, but Super Duplex has a higher chromium and molybdenum content, giving it considerably increased resistance to corrosion than its counterparts.

The material for UNS S32760 Stud Bolts is about 10% lighter when compared to grade 316 stainless steel. The Stud Bolt S32760 demonstrates high performance at cryogenic temperature settings as well. Which means that the ASTM A1082 UNS S32760 has good sub-zero notch ductility properties down to a temperature of minus 50¡ãC.

This alloy is especially useful in the -50¡ãF/+600¡ãF temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some restrictions, especially when used in welded structures.

The Super Duplex 2507 Pipe is made with 25% of chromium, 4% of molybdenum, and 7% of nickel in their composition. As a result, these pipes possess superior corrosion and erosion resistance in various stress-induced environments.

S32760 has very good resistance to localized corrosion and stress corrosion cracking and high mechanical strength.

As experts in the field of fasteners, we recognize that this alloy can be used in a variety of applications including heat exchangers, piping, pressure vessels, tanks, fans, pulp and paper equipment, oilfield equipment and press rolls. At HT PIPE you can find Duplex Premium Gaskets in high quality.

SA 815 S31803 Weld Fittings have exceptional chemical properties along with higher strength and good resistance to corrosion. Therefore this grade is used for fitting manufacturing. SA 815 S31803 Long/ Short Radius Elbow display outstanding resistance to pitting, crevice corrosion and have excellent weldability. They are perfect if one is looking for a sturdy pipe with good formability. ASME B16.9 WPS UNS S31803 Elbow also exhibits excellent resistance to acetic and marine environments.

Duplex 2205 alloy is composed of high chromium and low or moderate nickel conutenut.

Due to the excellent physical and mechanical properties of Super Duplex, the quality of Super Duplex steel fasteners can meet the high demands of the gas, oil and marine industries.

This category of material includes grades 2205, F51, F53, and F60. Duplex stainless has increased in popularity over the years due to its excellent chemical and mechanical properties versus their basic stainless counterparts, given especially that the cost differences are minimal now as the availability has increased.

ASTM A182 F51 flanges refer to pipe flanges made from the forged duplex stainless steel grade UNS S31803 for use in pressure systems.

Inhibiting deformation and cracking at high temperatures, the dual phase steel S31803 / S32205 reducer is superior to common steel parts in the chemical industry that are susceptible to chloride stress corrosion cracking. With flue gas desulfurization machinery. Tees such as ASME A182 Duplex Steel S31803/S32205 are known to have good resistance to high toxicity and elasticity.

Preheating of UNS S32750 Super Duplex Fasteners is not necessary except to prevent condensation on cold metal.

Applications for duplex 1.4462 coated studs are the oil and gas industry, marine industry, chemical industry, paper and pulp industry, etc. We offer Lean Duplex and Standard Duplex in a wide selection of duplex grades. Duplex 2205 studs have specific properties for different environments. The chemical composition of the duplex 2205 material has chromium, nickel and molybdenum in the composition. Duplex 2205 studs are cost-effective and lower than other duplex grades and are in high demand.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

ASTM A479 Duplex Steel UNS S32205 Round Gaskets are nitrogen reinforced duplex alloys formed to address common corrosion problems found incidentally with 300 series alloys. ASME SA 479 Duplex Steel UNS S31803 Machined Washers are hardened at 1868 to 1958 degrees Fahrenheit and then water quenched.

Duplex steels are also magnetic, a property that can be used to easily distinguish them from ordinary austenitic stainless grades.

The high oxidation resistance property of Grade 2205 is marred by its embrittlement above 300¡ãC. This embrittlement can be modified by a full solution annealing treatment. This grade performs well at temperatures below 300¡ãC.

2205 has excellent corrosion properties, and it is well-suited to environments containing chlorides and hydrogen sulphide, for use in oil and gas extraction from sour wells, in refineries and in process solutions contaminated with chlorides.

Duplex 2507 is a super duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel. This alloy is designed for applications requiring excellent strength and corrosion resistance.

2507 has Good general corrosion resistance, Suggested for applications up to 600¡ã F, and Low rate of thermal expansion.

Since the material is also resistant to acids and chlorine compounds, it could see its application in marine environments, especially in saltwater containing chlorine compounds. The ferritic portion of the duplex structure of Super Duplex 2507 round bar alloy makes it resistant to stress corrosion cracking in warm chloride-containing environments.

ASTM A240 UNS S32750 sheet is a type of steel known as super duplex steel.

2507 is used for oil and gas industry equipment, offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, and injection and ballast water systems.
