Duplex Stainless Steel

Product Details:

Ferralium 255 – SD50 (UNS S32550)Ferralium® 255 – SD50 (super duplex 255) is a super duplex stainless steel supplied in the hot worked and annealed condition. It achieves higher strengths than most stainless steels and alternative corrosion resistant alloys, offering the potential to reduce section size and therefore weight and cost.

As a 25% Cr alloy, with significant additions of copper, Ferralium® 255 offers excellent corrosion resistance in a wide variety of corrosive chemicals including sulphuric, nitric and phosphoric acid. In seawater and other chloride containing environments it also provides outstanding resistance to pitting and crevice corrosion, with Critical Pitting Temperature exceeding 50°C. Excellent ductility and impact strength at both ambient and sub-zero temperatures combine with a high resistance to abrasion, erosion and cavitation erosion.

2205 Duplex Overview

Duplex 2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. Often referred to as the work horse grade, 2205 is the most widely used grade in the duplex family of stainless steels.

The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance).

Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. Extended elevated temperature exposure can embrittle 2205 stainless.

Corrosion Resistance

2205 duplex stainless steel is a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking.

The combination of chromium, molybdenum and nitrogen convey the good resistance of 2205 to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environments.

With our trained professionals, we supply Duplex Stainless Steel 329. Our company offers this with the following

 

• Duplex Stainless Steel 329 was one of the earliest duplex steel which is reflected in its higher permitted carbon content

• Its resistance to pitting (PREN about 32) and to crevice corrosion is below that of super duplex steels, therefore use in seawater is limited

• Exposure to moderate and high temperature and less rapid cooling may cause embrittlement

• Accordingly, design stress values in ASME II do not extend above 260°C for S32900

• Impact values are high at room temperature. However, the proportion and orientation of ferrite in welds and base material may significantly affect toughness at subzero temperatures

Duplex 2205 Stainless Steel
Ragavendra inventory now includes Duplex 2205 (UNS S32205 / S31803), in sheet, sheet coil, plate, plate coil, round bar, processed flat bar and tubular products. Duplex 2205 is ideally suited for high-pressure and highly corrosive environments
General Properties
Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.
Applications:
Chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangersOil and gas exploration and processing equipment – piping, tubing, and heat exchangersMarine and other high chloride environmentsEffluent scrubbing systemsPulp and paper industry – digesters, bleaching equipment, and stock-handling systemsCargo tanks for ships and trucksFood processing equipmentBiofuels plantsStandards:

Corrosion Resistance:
Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environmentsChromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutionsResistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)The presence of ferrite provides for good performance of Duplex 2205 in caustic environmentsHeat Resistance:
Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperaturesSubject to embrittlement when exposed to temperatures above 572°F (300°C) even when exposed for short periods of time; Duplex 2205 is therefore not recommended for use above 572°F (300°C)

Product Details:

ASTM A815 ~ S31803Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades. Duplex stainless steels are in most cases, tougher than ferritic stainless steels. Strengths of duplex stainless steels can in some cases be double that for austenitic stainless steels.Whilst duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. However, the corrosion resistance of the least resistant duplex stainless steels is greater than that for the most commonly used grades of stainless steels, i.e. 304 and 316.Duplex steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.Property data given in this document is typical for flat rolled products covered by ASTM A240/A240M. ASTM, EN or other standards may cover products sold. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

Our duplex Stock is unmatched in the industry and our offering covers a full palette of duplex stainless steels for use in diverse industries and applications. The high mechanical strength of duplex grades is a result of the duplex microstructure and the alloying with nitrogen. This high strength gives opportunities for reducing both weight and cost as a thinner material can be used. Low nickel content of the duplex grades makes them price stable.The duplex grades LDX 2101® and 2304 are referred to as lean duplex grades. Typical applications are storage tanks, bridges, water heaters and reinforcement bars. The corrosion resistance is comparable to the standard austenitic grades like 4301 and 4404 respectively or high alloyed ferritics like 4521.Grades 2507 and 4501 are regarded as super duplex grades. They are highly alloyed and have a corrosion resistance comparable to high performance austenitics like 254 SMO®. Typical applications for super duplex are desalination plants, seawater systems, flue-gas cleaning, umbilicals, storage tanks and pressure vessels.By lowering total material weight, you also lower transportation and assembly costs, reducing environmental impacts even further – making duplex stainless steel a genuine material of the future.
