The carbon content in the Sa182 F9 flange is lower, so the weldability of this alloy is much better. Generally, higher carbon content in alloys promotes intergranular corrosion, especially during high heat treatments such as welding.

Chromium-molybdenum alloy flanges connect pipes, valves, pumps and other equipment to form a piping system. They are ideal for applications that convey corrosive or high temperature fluids or gases.

The size of these forgings range from ? NB to 250 NB and length of these forgings is 2mm to 40mm.

While chromium is an important alloying agent in a335 P91 piping, it is known to prevent corrosion and has a high resistance to oxidation at high temperatures. Since these pipes are surface treated or coated, they are also protected against corrosion. Surface coating can be accomplished by various techniques such as passivation, phosphating, oil immersion, varnishing and shot peening.

El grado B7 es un acero de baja aleacion de cromo molibdeno tratado termicamente con un requisito minimo de resistencia a la traccion de 125 ksi (860 Mpa), un limite elastico de 105 ksi (720 Mpa) y una dureza maxima de 35HRC. Boltport produce pernos con cabeza y sin cabeza B7 a partir de barras de acero aleado AISI 4140 o piezas forjadas.

It is almost the same as AISI 4130 chrome-molybdenum alloy steel, but with a slightly higher carbon content. Compared to AISI/ASTM 4130 alloy steel, AISI 4140 steel has a higher carbon content, which provides higher strength and heat treating capability, but also has limited weldability.

Grade B7 is a heat-treated chromium-molybdenum alloy steel with minimum tensile requirement of 100 ksi, yield of 75 ksi and maximum hardness of 35 HRC.

The composition of the chrome-molybdenum alloy steel pipe in A335 makes it ideal for power plants, refineries, petrochemical plants and oilfield services that transport fluids and gases at extremely high temperatures and pressures.

A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.

ASTM A182 F5 belongs to the American standard Martensite type heat-resistant steel forgings, implementation standard: ASTM A182-2016

We are a manufacturer, supplier and exporter of Plate Flanges, which are accepted by major industries as a cost-efficient alternative to other types of flanges whose cost increases due to its expensive production pattern.

L7 threaded studs and short head bolts are readily available in the market.

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.

These ASTM A182 Grade F5 Flanges gives extraordinary erosion resistance in, for instance, caustic and acidic applications which includes sulphuric and higher chloride environments. A182 Gr F5 Threaded Flanges are mostly used in utility services such as air and water. It is similar to the Slip-On flange, but the bore is threaded. Its greatest advantage is that it can be assembled without welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.

The A335 p12 material composition includes carbon up to 0.05 ¨C 0.15, manganese up to 0.30 ¨C 0.61, sulfur and phosphorus up to 0.025, silicon up to 0.5, chromium 0.80-1.25 and molybdenum up to 0.44-0.65. This steel shall meet the specified chemical composition, tensile properties and hardness requirements.

ASME SA 335 P91 Alloy Steel Pipe also has some other great features like low maintenance, efficient work, high demands, etc. We offer a range of ASTM A335 P91 alloy steel pipes for a wide range of applications in various industries.

Alloy steel pipes are common in applications involving automobiles, kitchenware, and industrial equipment. Typically, superalloy steel boiler tubes are used in applications with ambient temperatures exceeding 500¡ãC. For example, hollow and thin-walled alloy steel drill pipes must be able to resist pressure differences that manifest between the inside and the outside of these alloy steel seamless pipes.

Alloy C276 (UNS designation N10276) is a nickel-molybdenum-chromium-iron-tungsten alloy
known for its corrosion resistance in a wide range of aggressive media.

Too many good properties found in the same product just because of better sheet production. These are high tensile strength, good dimensional accuracy, surface finish, flexibility and durability, withstand heavy loads, strong construction and corrosion resistance. Resistance to corrosion, stress corrosion cracking, crevice corrosion cracking, oxidation/pitting corrosion makes it suitable for a variety of applications.

Chromium-molybdenum alloy steel has strong crack resistance under high temperature and high pressure. Chromium molybdenum is also resistant to hydrogen attack and hot sulfide corrosion cracking.

The Alloy Steel F12 Flanges are also very strong due to the annealing of them. Grade F12 Flanges can be supplied in either normalized or quenched and tempered conditions. Alloy Steel F12 Weld Neck Flanges is appropriate to various applications where its different remarkable characteristics are sought-after but a brushed/polished finish is not necessary.
