The ASTM A182 F51 flanges refer to standard or non-standard flanges manufactured in accordance with ASTM A182 Grade F51, which is designated with UNS number S31803.
Astm A182 F51 flange is made up of carbon, chromium, manganese, silicon, phosphorus, sulfur, nickel, nitrogen, molybdenum and iron.
The A182 Gr. F51 / S31803 material is a typical duplex stainless steel, which contains approximately 50% ferrite and 50% austenite.
The 21% chromium content is the key to extreme corrosion resistance and strength of the SA 182 f51 flanges. HT PIPE is a leading supplier and manufacturer of the flanges in various scales, shapes and types.
The combination of the ferritic phase and austenitic phase provides both high strength and excellent corrosion resistance.
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.
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.
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.
Duplex stainless is a mixed microstructure of austenitic and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades with similar corrosion resistance qualities.
Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking (including sulfide stress corrosion cracking), pitting, crevice corrosion and high strength when compared with other stainless alloys.
