    Detailed Information

    Manufacturer & Supplier of Stainless Steel 304 Flange in Mumbai, India

    Our UNS S30400 Stainless Steel Weld Neck Flanges come in a variety of schedules that can oblige the inward distance across of pipes and are handily distinguished because of the tapered hub that it sports. Stainless Steel A182 F304 is a standard, austenitic 18/8 stainless steel grade. ASTM A182 grade f304 is one of  the most versatile and most commonly used stainless steel grades today. SA182 f304 has excellent forming as well as welding properties. The balanced austenitic microstructure of 304 stainless steel flanges enables it to be severely deep drawn without the need for intermediate annealing. Which means that this stainless steel grade is dominant in the manufacture of drawn stainless parts in kitchen equipments such as  sinks, hollow-ware and saucepans.

    Non-magnetic alloy SS 304 Flanges is the most versatile and the most widely used of all stainless steels. SS 304 Slip On Raised Flanges has lower cost, where reduced corrosion resistance and fabrication characteristics are acceptable. A lower stress relieving temperature of 400 Degree C maximum must be used in Stainless Steel 304 Blind Raised Flanges. To solution anneal, cool this SS 304 Weld Neck Flanges rapidly in air or water from about 1850 Degree F to 2050 Degree F. Stainless Steel 321 Flanges may also be used as an alternative to Stainless Steel 304 Socket Weld Flanges if heavy section welding is required and post-weld heat treatment is not possible.

    Stainless steel 304 flanges can be readily braked or roll-formed into a various forms that are to be used for applications in the industrial, architectural, as well as transportation fields. ss 304 slip on flange also has outstanding welding characteristics. Post-weld annealing treatment in the ss 304 blind flange is not required while welding thin sections. Although Heavy welded sections in 304 stainless flanges may require a post-weld annealing treatment in order to achieve maximum corrosion resistance. Additionally, astm a182 f304 stainless steel is also subjected to stress corrosion cracking above a temperature of 60 °C. Stainless Steel 304 Orifice Flanges becomes slightly magnetic when cold worked. Therefore, ASTM A182 304 flanges are extensively used in heavy gauge components. Heavy gauge equipment’s are over about 6mm in thickness.

    As a largest manufacturer of SS 304 Flanges, we also offer a wide range of Stainless Steel ASTM A182 304 Flanges such as SS 304 Slip On Flanges, SS 304 Weld Neck Flanges, SS 304 Socket Weld Flanges, SS 304 Blind Flanges, SS 304 Orifice Flanges, SS 304 Spectacle Blind Flanges, SS 304 Screwed / Threaded Flanges, SS 304 Reducing Flanges, SS 304 Ring Type Joint Flanges (RTJ) etc.
