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 .

Duplex alloys have some of the ferritic stress corrosion cracking resistance of common austenitic stainless alloys and many of the superior formability properties that are more cost effective than high nickel alloys.

S31803 Duplex Steel is a 22% chromium duplex (austenitic/ferritic) steel with moderate to good strength and good general corrosion/stress corrosion/cracking resistance.

2205 duplex stainless tubing material, which is why it is referred to as a self-repairing layer.

SAF2507 thread rod have high strength, resistance to pitting, stress corrosioni cracking, erosion and corrosion fatigue, crevice corrosion resistance.

Duplex steel UNS S32205 fasteners are used in the pulp and paper industry such as digesters, bleach plants and stock handling systems. Also known as WNR 1.4462 fasteners, they are developed and designed in our infrastructure to international quality standards to the highest quality standards.

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.

ASTM A182 F53 Flange is a high strength flange that has 550MPa minimum yield strength and 800MPa minimum tensile strength.

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

S32760 is a super duplex stainless steel with a ferritic-austenitic microstructure.

Duplex steel UNS S31803, UNS S32205 round rods and wires are widely used in chemical, oil and gas, fertilizer and other application industries.

This increase in alloyants is what gives the super duplex stainless steels greater corrosion resistance properties.

S32760 also has high strength and extended service life. It is 10% lighter than grade 316 steel, ideal for sub-zero use, and more cost-effective than nickel alloys. Stainless steel grade F55 can be easily machined and welded.

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.

S32760 super duplex stainless steel is more resistant to pitting and crevice corrosion than regular austenitic or duplex stainless steels and is suitable for use in corrosive environments. This is due to higher additions of chromium, molybdenum and nitrogen.

Alloy 32750 is a super duplex stainless steel supplied in hot worked and solution annealed conditions.

Super Duplex Alloy UNS S32750 (F53 / 1.4410 / Alloy 32750 / Alloy 2507) combines the most desirable characteristics of both ferritic and austenitic steels.

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.

It is alsohighly resistant to inorganic acids, especially if they contain chlorides.

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.

The UNS S32750 standard of Pipe Fittings consists of 25% chromium, 4% molybdenum, and 7% nickel. The UNS S32750 Pipe Fittings have a 50-50 microstructure of ferritic and austenitic steel grades with improved strength.

The Benefits of Duplex Stainless Steel are improved Strength, because many duplex grades are as much as two-times stronger than austenitic and ferritic stainless steel grades, high Toughness and Ductility, high Corrosion Resistance, and Cost Effectiveness.

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.

The yield strength of this material is almost two times that of the usually used austenitic stainless steel grade.

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.

UNS S32750 Bolts are used for the assembly of two unthreaded components, with the assistance of a nut. UNS S32750 Bolts are known to have superior properties such as high tensile and yield strength.

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.
