ASTM A240 is a normative standard covering several chromium-based stainless steel grades manufactured in sheet, sheet, or ASTM A240 Gr 2205 strip.

Hex head bolts are ideal for many types of industrial fastener applications. The six-sided design of the 2205 Hex Bolt allows the bolt to be tightened or loosened quickly and efficiently, improving overall work speed and quick turnaround. Some additional benefits associated with using UNS S32205 Hex Bolts (also known as S31803) include: Extremely strong, hot forged, ASTM A449 and SAE J429 specified, improved corrosion resistance.

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

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.

ASTM A479 Super Duplex 2507 Hex Bolts combines high strength and good ductility with outstanding corrosion resistance qualities. The higher chromium, molybdenum and nitrogen contents in these ASME SA 479 Alloy 2507 Hex Bolts result in a Pitting Resistance Equivalent number (PREN) of >40.

Duplex steels are characterised by high chromium (19¨C28%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. The most used duplex stainless steels are the 2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7% Nickel); 2507 is known as ¡°super duplex¡± due to its higher resistance to corrosion.

Light gauges of 2507 material can often be used to achieve the same design strength of thicker nickel alloys. Duplex 2507 plate is suitable for applications requiring excellent strength and corrosion resistance. It contains 25% chromium, 4% molybdenum and 7% nickel.

Super Duplex UNS S32750 /F53 Flanges are made from a super duplex stainless steel grade that has 24% chromium, 3% molybdenum, 6% nickel and carbon, manganese, silicon, sulfur, phosphorus, nitrogen and iron in the composition.

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

Super Duplex Pipe Suppliersis known to have better pressure erosion, splitting obstruction and mechanical properties than some other kind of steel.

In duplex steels, the duplex microstructure has the high strength of ferritic grades while retaining the corrosion resistance of austenitic grades. It is not uncommon to use this metal as a practical solution to chloride-induced stress cracking, the Achilles heel of stainless steel.

The applications include high corrosive applications including acidic applications due to the material composition.

Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel tube in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

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 A240 UNS S32750 Plate is a stainless steel alloy with excellent resistance to chloride stress-related corrosion cracking.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

Super Duplex 2507 cannot be strengthened by heat treating. Annealing is performed at 1920¡ãF – 2060¡ãF (1049¡ãC – 1127¡ãC), followed by rapid cooling.

The duplex material contains bot the austenitic and ferrite structures in the metallurgy of the material. These properties bring the material the best of both ferritic and austenitic steel types. The pipes could be hot rolled or cold drawn. The hot rolled ones are stronger and the cold drawn ones are seamless and accurate in dimensions. The Duplex Seamless Pipe is used in applications with high precision requirements.
