This means that it derives its superior ductility and corrosion resistance from the austenite in the alloy, and the Werkstoff No 1.4462 BLRF flange has higher strength and hardness, both of which are ferritic part.
Compared to austenitic stainless steels, duplex stainless steels have higher tensile and yield strengths and significantly improved resistance to chloride SCC (stress corrosion cracking). They also exhibit higher toughness than ferritic stainless steels.
The high temperature strength of dual phase steel slip flanges is similar to alloy grade 430 in the temperature range of 950 to 1150¡ãC. However, the tensile strength of these flanges increases rapidly below 900¡ãC.
Duplex 2205 is a nitrogen enhanced duplex stainless steel designed to solve common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic (such as 304 stainless steel) nor purely ferritic (such as 430 stainless steel).
The structure of 2205 duplex stainless steel consists of a pool of austenite surrounded by a continuous ferrite phase. In the annealed condition, 2205 contains approximately 40-50% ferrite. 2205 is often referred to as the workhorse grade and is the most widely used grade in the duplex stainless steel family.
The advantage of the dual-phase structure is that it combines the advantages of ferritic alloys (resistance to stress corrosion cracking and high strength) with the advantages of austenitic alloys (ease of manufacture and corrosion resistance). The service temperature of 2205 duplex stainless steel should be limited to below 600¡ãF. Prolonged exposure to high temperatures can make 2205 stainless steel brittle.
For many applications where 300 series stainless steel is susceptible to chloride stress corrosion cracking, 2205 duplex stainless steel is a cost-effective solution. Stress corrosion cracking occurs when stainless steel is subjected to tensile stress while in contact with solutions containing chlorides. Elevated temperatures also increase the susceptibility of stainless steel to stress corrosion cracking.
The combination of chromium, molybdenum and nitrogen gives 2205 good resistance 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 content of 2205 provides better corrosion resistance than common stainless steels such as 316L and 317L in most environments. This exotic alloy is used in oil and gas exploration and is also used in the chemical processing industry .
The addition of niobium, along with molybdenum, hardens the matrix of the alloy and provides high strength without the need for a strengthening heat treatment. Other popular nickel-chromium alloys are age hardened by adding aluminum and titanium. This nickel steel alloy is easy to manufacture and can be welded in the annealed or precipitation (age) hardened condition. This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution control equipment and nuclear reactors.
Incoloy 800 flanges (B564 N08810 blind flanges) can be used in heat treatment equipment, chemical and petrochemical processing. Alloy 800 flanges are non-magnetic, high strength and good weldability.
Incoloy 8Incoloy 800 H is an iron-nickel-chromium alloy with the same basic composition as Incoloy 800 with significantly higher creep rupture strength. Higher strength results from tight control of carbon, aluminum and titanium content and high temperature annealing. The 800H modification is to control carbon (0.05 to 0.10%) and grain size (>ASTM 5) to optimize stress fracture properties. Incoloy 800 H has further modifications to the combined titanium and aluminium content (0.85 to 1.2%) to ensure optimum high temperature performance. The alloy is double certified and combines the properties of both forms.

Inconel 718 has good resistance to oxidation and corrosion at temperatures within the effective strength range of the alloy in the atmospheres encountered in jet engine and gas turbine operation.
Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a variety of severe corrosive environments, pitting and crevice corrosion. This nickel steel alloy also exhibits extremely high yield, tensile and creep rupture properties at elevated temperatures.
Uses of this nickel alloy range from cryogenics to long-term use at 1200¡ãF. One of the distinguishing features of the Inconel 718 composition is the addition of niobium to allow age hardening, allowing annealing and welding without spontaneous hardening during heating and cooling.
ASTM B564 UNS N10276 Flanges have a small amount of tungsten added to help resist the growth of grain boundary precipitates that reduce corrosion resistance. Hastelloy C22 flanges have better corrosion resistance than most other grades and are an upgrade to the C276 Hastelloy grade. They are important flanges because of their excellent versatility and resistance to chloride-induced pitting.

Alloy 600’s high nickel content provides resistance to reducing environments, while the material’s chromium content provides resistance to weaker oxidizing environments. The material has excellent resistance to chloride stress corrosion cracking.
The high nickel content of Alloy 600 provides good resistance to moderately reducing conditions. The nickel content of the alloy makes the alloy extremely resistant to chloride ion stress corrosion cracking. Alloy 600 is an alloy used in magnesium chloride solutions.
