A182 F53 2507 special flange used in offshore platforms and heat exchangers

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 .

Compared with ferritic stainless steel and austenitic stainless steel, duplex stainless steel pipe has good welding performance. It is neither like the welding heat affected zone of ferritic stainless steel, because of the grain coarsening, the plastic toughness is greatly reduced, nor like austenitic stainless steel, it is more sensitive to welding hot cracks.

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.

Applications for duplex 1.4462 coated studs are the oil and gas industry, marine industry, chemical industry, paper and pulp industry, etc. We offer Lean Duplex and Standard Duplex in a wide selection of duplex grades. Duplex 2205 studs have specific properties for different environments. The chemical composition of the duplex 2205 material has chromium, nickel and molybdenum in the composition. Duplex 2205 studs are cost-effective and lower than other duplex grades and are in high demand.

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.

Inhibiting deformation and cracking at high temperatures, the dual phase steel S31803 / S32205 reducer is superior to common steel parts in the chemical industry that are susceptible to chloride stress corrosion cracking. With flue gas desulfurization machinery. Tees such as ASME A182 Duplex Steel S31803/S32205 are known to have good resistance to high toxicity and elasticity.

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.

2507 Super Duplex Stainless Steel was designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

All Duplex 2205 Seamless Pipe produced according to the ASTM A789 must be furnished in a heat treated condition.

A182 F51 Duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.

Compared with austenitic stainless steel, F51 duplex stainless steel has twice the compressive strength, and compared with 316L and 317L, the designer can reduce its weight.

2507 is used for oil and gas industry equipment, offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, and injection and ballast water systems.

These grades of super duplex stainless steel fasteners are used when applications require excellent corrosion resistance and strength. Composed of nitrogen, molybdenum and chromium, they have excellent resistance to crevice corrosion and chloride pitting.

This provides the flanges with high corrosion resistance and higher mechanical properties. Please contact us for your orders of F53 flanges.

The formation of ASTM A479 duplex steel UNS S32205 tie rod consists of a pool of austenite surrounded by continuous ferrite phases. ASME SA 479 Duplex Steel UNS S31803 Tie Rods are hot worked in the temperature range of 1750¡ãF to 2100¡ãF. This is designed to reduce the depth used in fabrication, thereby reducing the weight of precise significance for items such as pressure vessels, structural functions, etc. As ASTM A479 dual phase steel for bridges, storage tanks, etc. UNS S32205 rebar has approximately twice the superior performance of SS 304 .

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.

The material has high strength and corrosion resistance. The A182 F53 material is used to make flanges ranging from 1/2 inches to 48 inches under different standards such as ANSI, ASME, DIN and other international standards.

Astm A182 F51 flange is made up of carbon, chromium, manganese, silicon, phosphorus, sulfur, nickel, nitrogen, molybdenum and iron.

There are SA 182 F53 S32750 Blind Flanges, socket weld flanges and weld neck flanges in this range of material. The different flanges are used in different applications set ups.

Duplex 2205 fasteners are made from standard duplex materials. The material consists of carbon, manganese, silicon, phosphorus, 21% chromium, 2.5% molybdenum, 4.5% nickel and nitrogen.

The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.

From corrosion resistance to strength, businesses around the world appreciate these properties of 2507 Super Duplex Seamless. Due to the dual microstructure phase, the weldability of this alloy is classified as good, which is why a relatively robust and durable super duplex welded pipe can be achieved.

Another advantage of grade 304 stainless steel bar over grade 303 is that it is slightly harder and has better corrosion resistance. Because of this, grade 304 stainless steel bar is used in large quantities in the manufacture of fasteners and fixtures such as nuts, bolts, washers, clips, fittings and clamps. Products made from grade 304 stainless steel in the fastener industry are often referred to as “A2”.

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

We are suppliers of WNR 1.4410 Super Duplex Steel Weld Neck Flanges with matching stub-ends that withstand alkalis under higher temperatures.

S31803 has been supplemented by S32205 which has a higher minimum N, CR and Mo.

Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. This grade offers higher resistance to corrosion

Super Duplex Stainless steels, which combine high strength and excellent corrosion resistance in many environments, have found applications in chemical and process industries.

Duplex 2205 has higher resistance to crevice and erosion corrosion than sus316L austenitic stainless grades.

Duplex steels are also magnetic, a property that can be used to easily distinguish them from ordinary austenitic stainless grades.
