Alloy Steel Flanges stockist
Alloy Steel Flanges

Alloy Steel Flanges stockist  are offered with a Mill Test Certification, NACE 3.1 Certification and after world class Third party inspection. Our Alloy Steel Flanges are used in Marine engineering, Heat exchangers, Pumps Chemical processing, Hydro-Alloy processing, Petrochemical plants, Valves, Nuclear power projects, Oil & Gas equipment. Alloy Steel Flanges has great resistance to stress corrosion cracking and also gives high resistance to corrosion fatigue and erosion corrosion. Our flanges faces are also made to standardized dimensions and are typically flat face (FF), slip-on flanges (SO), raised face (RF) or ring joint (RJT) styles. Flanges designs are available as weld neck flanges (WN), lap joint flanges (LJ), plate flanges (PL), socket weld flanges (SO), blind flanges (BL), threaded / screwed flanges (TH), orifice flanges, orifice plate, spectacle blind, spectacle flange, blind spacer and also blank. Ready stock of Alloy Steel Flanges in Seamless and Welded to immediate delivery for break down & in ongoing projects. Alloy Steel Threaded Flanges stockist combines good ductility, high strength and with outstanding corrosion resistance qualities.

What is a Alloy Steel Flanges

Alloy Steel Flanges has supreme quality, high strength, sturdy construction, flawless finish and ехсеllеnt gеnеrаl соrrоsіоn rеsіstаnсе tо sulfurіс асіd аnd tо сhlоrіdе strеss соrrоsіоn сrасkіng. These Alloy Steel Slip-on Flanges with chromium contents of at least 20 % tо 40 %, can be used at temperatures up to 1725 Degree F – 1850 Degree F (941 Degree C – 1010 Degree C). C. Alloy Steel RTJ Flanges have no appreciable price difference between alloy steel flange. Alloy Steel Long Weld Neck Flanges have temperature range where corrosion resistance is important. Alloy Steel Blind Flange is resistant to atmospheric conditions, water and some chemicals. Flat Face and Raised Face Flanges is mostly used in the alloy steel flange family.
