These alloys typically comprise of about 1 % to 5% of the steel’s content and are usually added based on their ability to provide a very specific attribute for their end use.

Our ASTM A182 F5 alloy steel blind flanges are used in auxiliary industrial high pressure services such as heat exchangers, condensers, evaporators, boilers, etc.

Which means that one has to know if the alloy steel flange material is critical to achieving good weld integrity and the need for proper filler metal selection.High heat resistance steel grades are generally known as Chromium Molybdenum Steel.

ASTM A182 Gr F1 Blind Flange is a solid disc used to block a pipe or create a stop. It is similar to an ordinary flange, with mounting holes around it, and the sealing ring is machined into a mating surface.

The addition of molybdenum strengthens the elastic limit of the A335 p11 welded pipe and increases its temperature strength. In addition to these properties, there is a reduction in brittleness and an improvement in the weldability and hardenability of the pipe.

ASTM A182 F11 Alloy Steel Flanges are used in manufacturing of flanges and fittings and are used in industries where cold temperature is observed and corrosion resistance doesn¡¯t matter much.

ASTM A182 is the Standard Specification for Forged Stainless Steel Pipe Flanges and Stainless Steel Forged Fittings.

There are reducing elbows, long radius elbows and short radius elbows in this grade.These fittings are heat treated during their manufacture.

ASTM A320 L7 washers are specially engineered for LOW temperature performance. These fasteners are commonly used for valves, flanges, fittings, and pressure vessels.

ASTM A194 Grade 2H Nut is a carbon based steel heavy duty nut. It is a commonly used high strength nut.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

Alloy Steel Flanges, Alloy Flanges are carefully designed using current technology under the visionary guidance of accomplished professionals in the manufacturing sector.

ALLOYS STEEL SA 182 F9 has excellent strength and excellent corrosion resistance at high temperatures.

A335 p9 pipes are made of ferritic alloy steel for high temperature applications. The sa335 p9 material chemically contains metals such as molybdenum and chromium added to the alloy. By adding metals such as molybdenum and chromium, the tensile strength of the alloy is increased. The yield strength of the a335 p9 welded pipe is 205 Mpa, while its tensile strength is 415 Mpa. The elongation of the pipe is about 30%.

The material has high creep resistance and corrosion resistance. The molybdenum content provides creep resistance and pitting resistance to the pipe. ASTM A335 P22 pipe is suitable for high temperature service. The ability to use at high temperatures comes from the ingredients. The composition of ASTM A335 P22 welded pipe contains carbon, manganese, phosphorus, sulfur, silicon, chromium and molybdenum.

Although acceptable fouling levels are considered beneficial to the alloy, in moderate cases, fouling deposits on Astm A182 F9 flange surfaces can act as a barrier to excessive corrosion. When flanges are produced using specification ASTM A182, they work well at high temperatures, albeit in applications with high pressure.

Flanges that can withstand harsh environments are critical when transferring high temperature or corrosive media from one process to the next through chrome alloy tubing.

A335 grade P5c pipe is a low alloy carbon steel (Cr-Mo) self-quenching in air where high hardness and residual stress are required for welding and it is not recommended for direct use in services requiring critical conditions. This situation requires the application of post weld heat treatment (PWHT). If you want to avoid PWHT then you can use preheat (120¡ãC) when soldering A335 grade P5c tubes. PWHT is required if the thickness of ASTM A335/ASME SA335 P5c alloy steel pipe is greater than 13 mm.

A blind flange is a solid flange as shown below. The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used.

A182 F5 material is an excellent alloy that is hardened only by cold working. It is often used in nuclear energy, medical equipment, chemical energy, etc. These ASTM A182 Grade F5 Flanges gives extraordinary erosion resistance in, for instance, caustic and acidic applications which includes sulphuric and higher chloride environments.

The key to the P5 composition of chromium-molybdenum alloys is the addition of chromium and molybdenum. Chromium or chromium increases high temperature strength, increases oxidation resistance and increases tensile, yield and hardness at room temperature. Molybdenum improves strength, elastic limit, wear resistance, impact quality and hardenability. It increases resistance to softening, inhibits grain growth, and makes chrome steel less susceptible to embrittlement. Molybdenum is also the most effective additive for increasing high temperature creep strength or creep resistance. It also enhances the corrosion resistance of the steel and inhibits pitting corrosion.

ASTM A182 Alloy Steel Blind Flanges is a solid disk used to block off a pipeline or to create a stop. It has mounting holes around the perimeter and the gasket sealing rings are machined into the mating surface.

A182 alloy steel flanges are not only suitable for high temperature, but also for high pressure or a combination of the two.

The production of ASME SA182 F9 flanges will be done using alloys with lower carbon content. Reducing the carbon content in these alloys reduces the formation of carbide precipitates. This basically means that alloy steel F9 flanges will no longer be susceptible to intergranular corrosion in the heat affected weld zone.

Since these are heavy duty tension nuts, they are used in high vibration and high stress applications such as aircraft engine parts and automotive engine parts. ASTM A194 Class 2h material consists of all classes of carbon, manganese, phosphorus, sulfur and silicon.
