Stainless Steel 904L Flanges

Alloy 904L Flange and 904L Stainless Steel Flanges Manufacturer In India

Stainless Steel 904L Flanges

What is Stainless Steel 904L Flanges used for?

The SS 904l flange is a super austenitic grade that is seen in different applications. The flange is a feature in chemical processing, air pollution control, metallurgical processing, and oil and gas production. Its unique features also allow it to be used in the pharmaceutical industry, pulp, and paper processing equipment, and in seawater applications. Apart from this, it is also a feature in acetic, phosphoric, and gas scrubbing plants.

How are Alloy 904L Flange made?

The Alloy 904l flange can be manufactured following three main techniques. This includes casting, cutting the rolled plate material, and forging. The basic method for producing the flange includes processing the raw materials and then forming them to the correct specifications. The flanges are then tested and later packed to be shipped to the customer.

904L Stainless Steel Slip On Flanges advantages and disadvantages

The 904l stainless steel slip on flange is a versatile flange that is widely seen in the industry. These flanges have their set of advantages along with disadvantages. One of the biggest advantage of this flange is that it is easy to install and weld using fillet welds. The versatile flanges can handle low pressure and temperatures in different conditions. However, they showcase excellent resistance and tolerances in the system. The major disadvantage of these flanges is that they can’t handle higher pressures or temperatures. These flanges contain expensive ingredients making them a costly proposition for buyers.

characteristics of 904L Stainless Steel Blind Flanges

The 904l blind stainless steel flanges are non-stabilized austenitic steel. The low carbon flanges help in terminating the flow of media in the system efficiently. These flanges are screwed and can be readily dismantled. The nickel and molybdenum content allows the flanges to showcase outstanding corrosion and oxidation resistance properties. The blind flanges are tolerant to stress corrosion cracking, and pitting in harsh conditions. The alloy 904L blind flanges have excellent strength with outstanding mechanical properties and can be easily heat-treated. The robust grade can be easily welded and subsequently processed following standard shop welding procedures.
