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.

Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments

Zeron 100 Threaded Rod are available in hot forged,cold forged and bar stock machined conditions depending upon the order quantity.SA 182 F55 is a forging grade of Alloy 32760 or UNS 32760 which is highly resistant to crevice corrosion and pitting alloy for variety of corrsives. It is 22% chromium duplex stainless steel.

Super Duplex 2507 Lock Washers has excellent corrosion resistance in marine environments.Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.

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

It is listed in Material Group 2.8 according to ASME B16.5 and ASME B16.47.

Combining many of the beneficial properties of ferritic and austenitic steels, 2205 is the most widely used duplex grade. Its high chromium and molybdenum conutenut gives stainless steel excellenut corrosion resistance.

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.

The microstructure of ASME SA 479 Duplex Steel UNS S32205 Flat Washers includes a combination of ferritic and austenitic phases. ASTM A479 Duplex Steel UNS S31803 Gaskets have excellent general corrosion resistance in a variety of aggressive chemicals including industrial and seawater acids. Buy duplex stainless steel washers from us at leading market prices.

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.

The duplex microstructure gives this grade high strength UNS S32750 a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300¡ãC.

Duplex 2205 flanges combine the qualities of stress corrosion cracking resistance and high strength derived from being a ferritic alloy along with its austenitic fabrication capabilities.

It accounts for around 80% of overall duplex stainless steel production.

F51 duplex stainless steel is especially suitable for use in the temperature range of -50¡ãF/+600¡ãF, and can also be used for lower temperatures under strictly limited conditions (especially for welded structures).

Duplex stainless steel pipes and fittings are generally less expensive because of the lower proportions of alloying elements used in the manufacture of duplex stainless steels. Compared to austenitic stainless steels, duplex stainless steels have higher yield strengths, so users can buy duplex pipes and duplex pipe fittings in relatively lower thicknesses.

On average, duplex stainless steel is about twice as strong as either ferritic or austenitic stainless steels. High toughness and ductility. Duplex stainless steel can be more easily formed under pressure than ferritic grades and also have superior toughness.

2205 duplex pipe is not recommended to be used at a temperature above 572¡ãF. Due to the presence of higher chromium, molybdenum, and nitrogen contents, 2205 duplex stainless steel tubes demonstrates superior corrosion resistant properties in comparison to the more conventionally used austenitic stainless steel grades 316 and 316L in most environments.

The duplex steels are one type of stainless steels that have ferritic and austenitic phases in their metallurgic microstructure.

Super Duplex UNS S32760 Round Rod has many properties and properties due to the elements present in the chemical composition. Due to these characteristics and properties, these super duplex UNS S32760 round bars are used in a large number of industrial applications.

Duplex stainless steel (DSS) is featured with structure of two phases (¦Á and ¦Ã) and has characteristics of both ferritic and austenitic stainless steel. It has good corrosion resistance and high strength. It is alloyed with 18%-28% Cr and 3%-10% Ni in the condition of low C. Some steels also contain the alloy elements such as Mo, Cu, Nb, Ti and N, etc.

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.

2205 has good solderability. The motivation for welding dual-phase steels is to maintain the corrosion resistance, toughness and strength of the base metal in the weld metal and heat affected zone.

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

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.

There are components of duplex 2205 fasteners available such as studs, set screws, bolts, washers and nuts. Whenever you specifically consider duplex stainless steel 2205 gaskets, it can be of great benefit for different types of critical industrial applications often found in harsh environments. Almost all types of 2205 stainless steel gaskets will provide a never-ending supply and excellent range of service for different applications such as valves or nuclear, seawater, offshore buoyancy and petrochemical, pumps, etc.
