Stainless Steel 304 Flanges

Stainless Steel 304 Flanges

We are leading ASTM A182 F304 BLRF Flange Manufacturer, Check Dimensions of SS 304 Weld Neck Flange

Considered to be one of the more versatile varieties of stainless steel alloy grade Stainless Steel 304 Flanges is a popular choice amongst most buyers. This is because of several reasons. Primary among them is the fact that stainless steel 1.4301 aisi 304 flange is easily available and does not cause a dent in the pocket of our clients.

We are PED Approved supplier of 304 Stainless Steel Flanges in various form such as RTJ/ Plate/ Raised

After hot working, the forged product such as the specified ASTM A182 F304 Flanges is required to be cooled to a specific temperature before undergoing heat treatment. This heat treatment process conducted on the ASTM A182 specified SS UNS S30400 Pipe Flanges has to be performed keeping in accordance with certain requirements. For example, this particular specification mentions requirements such as heat treatment type, austenitizing or solution temperature, cooling media, as well as quenching to be conducted on the 304 Stainless Steel Flanges.

In addition to this, the specification also mentions that the said material, which in this case is SS 304 Blind Flange has to conform to the requirements as to not only the chemical but also mechanical properties for the grade ordered. The mechanical property requirements of the specified ASTM A182 alloy grade SS 304 Flanges include requirements such as elongation, tensile strength, yield strength as well as Brinell hardness.
