- We work with global industries!
We firmly believe in contributing to an enterprises progress, not only as a provider of goods and services but as a partner in building a strong and booming business. We, Rexton Steel & Alloys undertake several strategies and implement them through effective processes that add to the value of business. We are a manufacturer, supplier and exporter of Stainless Steel 321/ 321H Flanges that are precision-made, highly accurate in dimensions and are made using the most effective contemporary machinery and raw materials that are supreme in quality. Our SS UNS S32109 Forged Flanges are made using the forging process, using mechanical or thermal energy. They prevent the formation of any cavities during welding and have a better impact strength compared to Cast flanges, making them superior to use in the oil mills and mining industry.
As an acclaimed undertaking of the business, Rexton Steel & Alloys is included in offering an unfathomable cluster of Stainless Steel 321/321H Flanges as a maker, exporter, stockiest and supplier to our household and worldwide customers. Alloy 321 (UNS S32100) is titanium settled austenitic Stainless Steel Flanges with great general corrosion resistance. Alloy 321H (UNS S32109) Stainless Steel Flanges is the higher carbon (0.04 - 0.10) adaptation of the combination.
Regarding diverse evaluations, we offer these Flanges in various sorts, for example, SS Slip On Flanges, SS Blind Flanges, SS Weld Neck Flanges, SS Socket Weld Flanges, SS Spectacle Blind Flanges, SS Screwed/Threaded Flanges, SS Reducing Flanges, and SS Ring Type Joint Flanges (RTJ). In the interim, our costs of such spines are set remembering customers prerequisite.
As for national and global nature of crude materials, we likewise offer these SS 321/321H Flanges in tweaked sizes and thicknesses according to particular requests by our regarded customers at business sector driving costs.

| Threaded Flanges |  |
Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe. |
|---|---|---|
| Socket-Weld Flanges |  |
Socket-Weld Flanges has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe. |
| Slip-On Flanges |  |
Slip-On flange has a hole with matching outside diameter of pipe from which pipe can pass. The flange is placed on pipe and fillet welded from both inside and outside. |
| Lap Joint Flanges |  |
Lap flange is having two components, a stub end, and a loose backing flange. Stub end is butt welded to the pipe and Backing flange freely move over the pipe. |
| Weld Neck Flanges |  |
Weld neck flange are most widely used flanged in process piping. It gives the highest level of joint integrity due to Butt-welded with a pipe. |
| Blind Flanges |  |
The blind flange is a blank disc with bolt hole. These types of flanges are used with another type of flange to isolate the piping system |
| Screwed Flange |  |
3Screwed Flange is used to connect other components in non-critical applications, low-pressure in which no welding is required. |
| Reducing Flange |  |
A reducing flange consists of a flange with one specific diameter having different bore and smaller diameter. It s used to change the diameters in piping system. |
| Forged Flange |  |
They are designed by using corrosion free substance and using an advanced technology. Our team of experts identify each and every product to ensure the best quality and flawless of these products available at suitable rates |
| Orifice Flange |  |
Orifice Flange helps to measure the flow of liquids and gases using orifice meters located on the outside diameter of the flanges. The main purpose of the orifice flange identifies the flow rate of either liquid or gas in the pipeline system. |
| Spectacle Flange |  |
A spectacle flange is a specialty flange made of two metal discs attached in the middle by a small section of steel. Spectable flanges get their name because they look like a pair of reading glasses, or spectacles. |
