We are a professional manufacturer of steel forged chome moly steel A182 F11 flange in China, A182 F11 Blind flange,A182 F11 weld neck flange,ANSI B16.5 A182 F11 Slip on Flange, Chrome Moly Alloy Steel Flange,A182 F11 Cl2 Flange，
As an experienced A182 F11 flange manufacturer in China,we produce high quality A182 F11 forged flanges.
A182 F11 Chrome moly alloy flanges offer improved levels of chromiumand molybdenum. The added chromium helps increase the steel’s hardenability and corrosion resistance, whereas the increased molybdenum helps bolster itstoughness and corrosion resistance.
ASTM A182 F11 flanges are extremely ductile, strong and tough and easy to weld and offer oxidation and scaling resistance.which matches with ASTM A335 Gr P11 alloy steel pipes ,A234 WP11 Pipe fittings
A182 F11 Flange also known as 1 1/4 Chrome 1/2 Mo Flanges ,1.25 chrome 0.5 moly ,which is a chromium-molybdenum based low alloy-steel grade. It is characterized by 1 to 1.5% chromium – an average of 1%, hence the numerical nomenclature. All of our material is supplied in F11 Class 2 (CL 2), although we can also supply Class 1 or Class 3 upon request.
In some cases,A182 F11 Flange also can be used as an equivalent grade to 16Mo3 Flange
A182 F11 Class 1 Flange,A182 F11 Class 2 Flange,
A182 F11 (13CrMo4-5) IS A MILD STEEL WITH CHROME, VERY TOUGH, IT CAN BE CASE-HARDENED, IT CAN BE WELDED AND IT IS RESISTANT TO CREEP 550°C. IT IS USED FOR THE FABRICATION OF TUBES, BOILERS AND SUPERHEATERS OR FOR THE TRANSPORTATION OF OVERHEATED STEAM WITH A HIGH PRESSURE. IT IS EASILY MACHINABLE, EVEN AT THE RAW STATE OF ROLLING OR NORMALISED.

Heat treatment of ASTM A182/A182M F11 Flanges:
The starting material of the ASTM A182 Gr. F11 Cl. 2 flange shall be low-alloy ferritic steels made by the open-hearth, electric-furnace, or basic-oxygen process with the option of separate degassing and refining processes in each case. The material shall be forged as close as practicable to the specified flange shape and size. After hot forging, the flange sahll be cooled to a temperature below 538°C [1000°F] prior to heat treating. ASME B16.5 or ASME B16.47 flanges made of ASTM A182 Gr. F11 Cl. 2 steels shall be furnished in normalizing and tempering condition only. The minimum austenitizing temperature is 900°C [1650°F]. The normalizing requires air cooling, which is followed by tempering with minimum tempering temperature of 620°C [1150°F].
