Stainless Steel 304 Flange

Biggest ASTM A182 F304 Flanges Manufacturer In India, Suppliers Of SS 304 Blind Flange In Mumbai.

Largest supplier of small-quantity Of SA 182 Gr F304 Socket Weld Flanges, Check FNPT A182 F304 Flange Dimensions In MM, Buy Welded ASME SA182 Stainless Steel 304 Pipe Flanges At Factory Price In India.

ASTM A182 F304 are made up of a chemical alloy that contains 18% chromium and 8% nickel. The A182 F304 Material is specified by the austenitic chromium nickel steel alloy. A182 Grade F304 BLRF is a member of blind raised face (BLRF) flanges. These are usually used at the end of lines. These could also be used as inspection covers in systems where they are easy to remove and close. A182 Gr F304 SORF have a slip on raised face (SORF) and are usually attached to the pipe by fillet welding.  You can get our SS 304 Flanges Price List by contacting us.

Most reliable supplier of 720 psi SS 304 Flange, One of India’s largest Manufacturer Of 304 Stainless Steel Flanges, Largest Independent Stockholder Of Forged A182 Grade F304 Lap Joint Flanges, Exporter Of ASME B16.5 A182 Gr F304 Blind Flanges In Mumbai.

SS 304 Blind Flange is made of 304 stainless steel and is used in wide varieties of applications. Stainless Steel 304 Flanges come in different types such as the SS 304 Slip On Flange to hold the pipe inside or the SS 304 Blind Flange that ends the piping. 304 Stainless Steel Flanges are durable and less costly compared to other alloy types. ASTM A182 F304 Flanges contain low carbon in their composition. So, welding with A182 F304 Flange is reliable. This is because the A182 F304 Material is very much corrosion resistant even after welding. A182 Grade F304 BLRF retains its originality with long term usage.


What is F304 Material?


ASTM A182 F304 Stainless Steel Flanges

A182 Gr F304 SORF is a specification of raised face flanges with 13% chromium in its composition. It performs better than the SS 304 Slip On Flange in corrosive conditions due to the chromium content. Stainless Steel 304 Flanges make it easier to be used in systems where welding is needed. Due to the low carbon content of the 304 Stainless Steel Flanges the carbide precipitation during welding is lessened. This makes the flanges last long without rusting or corrosion.

Difference Between F304 And F304L


  • ASTM A182 F304 Flanges are made up of a chemical alloy that contains 18% chromium and 8% nickel. The A182 F304 Material is specified by the austenitic chromium nickel steel alloy.
  • Stainless Steel 304L Flanges make it easier to be used in systems where welding is needed. Due to the low carbon content of the 304L Stainless Steel Flanges the carbide precipitation during welding is lessened.
