Forged Flanges

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.

It is listed in Material Group 2.8 according to ASME B16.5 and ASME B16.47.

ASTM A182 F53 Flange is a high strength flange that has 550MPa minimum yield strength and 800MPa minimum tensile strength.

The pressure-temperature ratings for ASTM A182 F53 flanges are the same as that for other duplex stainless steels.

There are different types of flanges such as slip on flanges, socket weld flanges, forged flanges, blind flanges, reducing flanges and many by their functions.

The flanges shall not be used at temperatures over 600¡ãF [315¡ãC] since it may be subject to embrittlement after service at moderately elevated temperatures.

The flanges could also be manufactured as screwed, threaded or forged types. The forged flanges are made from a single piece of raw material. These are also called the cast flanges.

The flange a182 f53 can also differ in the face type as flat face, raised face and ring type joint flanges.

The astm a182 f53 vs f55 can come in different diameters ranging from ? inches to 48 inches with different pressure classes ranging from class 150 through class 2500.

The pressure capacities of the flanges can also be expressed in pressure numbers. The astm a182 f53 uns s32750 flange types come in pressure numbers ranging from PN6 through PN64.

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

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

A182 F53 material displays excellent corrosion resistance.

SA 182 F53 S32750 Flange is a super duplex stainless steel supplied in the hot worked and solution annealed condition.

The mechanical strength, corrosion resistance and low temperature toughness of the ASTM A182 F53 Flanges is higher than that of ordinary duplex stainless steels.

ASTM A182 UNS S32750 Flanges is the most common super duplex grade that has an enhanced pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types.

ASTM A182 F53 Super Duplex Flanges available with rating class of 150#, 300#, 400#, 600#, 900# and 1500# in sizes NPS 1/2 to 24.

For 2500# in sizes from NPS 1/2 to NPS 12 ASTM A182 UNS S32750 Flanges, with requirements in both metric and U.S. A182 S32750 Flat Flanges for companies involved in Equipment Manufacturing, Oil Refineries, Mining, Chemical manufacturing and Industrial Construction.

ASTM A182 F53 flanges refer to flanges made from super duplex stainless steel 2507 (UNS S32750) by a hot forging process.

ASTM A182 F51 flanges refer to pipe flanges made from the forged duplex stainless steel grade UNS S31803 for use in pressure systems.

UNS31803 has been supplemented by S32205 (F60) which dual conforms to S31803 but has a higher minimum N, MO, NI and Cr which guarantees a better corrosion resistance.

ASTM A182 F51 equates to UNS S31803. This was the original caption for a 22% Cr duplex stainless steel.

This grade, with a tighter specification, is captioned as F60, equating to UNS S32205. Consequently, S32205 can be dual-certified as S31803 but not vice-versa.

It accounts for around 80% of overall duplex stainless steel production.

It has the nominal composition of 22Cr-5Ni-3Mo-N with P number 10H.

With an increased chromium content compared with F51 it offers improved pitting corrosion resistance.

The yield strength is also higher, allowing component designers to reduce section size for load-bearing applications.

ASTM A182 Grade F51 is the standard duplex stainless steel and is also called ¡°duplex 2205¡± or ¡°alloy 2205¡±.

It reaches the phase balance of austenite and ferrite in roughly same volume fraction.

The duplex structure results in improved stress-corrosion cracking resistance, compared with the austenitic stainless steels, and improved toughness and ductility, compared with the ferritic stainless steels.
