Stainless Steel 304H Flanges Manufacturer & Supplier

Astec Tube supplies Stainless Steel 304H Flanges engineered for high-temperature service where standard 304 grade falls short. The addition of carbon content in 304H helps in improving the creep resistance and strength retention at elevated temperatures, because of these features this material is commonly preferred for refineries, power plants, and process piping systems operating well above ambient conditions. These flanges are produced in numerous sizes, pressure ratings and face types per ASTM A182 and ASME B16.5. Each batch is dimensionally inspected and material tested in our quality control prior to delivery. We manufacture flanges to constant, proven quality standards for small maintenance orders or large orders for new installations.

SS blind flanges are used wherein the demand of steel properties and resistance to general corrosion is there. Socket weld flanges are differing from the carbon steel by the chromium amount presented into it. SS lap joint flanges readily rust when it gets exposed to the moisture and air. As the iron oxide is having low density, in RTJ flanges film expands and tends to fall away. SS spectacle blind flanges are containing adequate amount of chromium for undergoing passivating, forming the not moving film of chromium oxide onto the surface.

We are the client ambitious industry that is offering SS 304H Flanges to the global and local clients at various specifications, standards, dimensions, sizes, classes/pressure, and flange face types, etc. Also, it is manufactured and provided at custom-made specifications as per the product drawings the clients provide to us. The designing of these flanges is done by using superior quality of alloy so that greater strength can be added so that it can withstand in any atmospheric condition.

These flanges are used in ranges of industrial applications. It is including specialty chemicals, petrochemicals, power generations, oil & gas industry, food processing, pulp & paper industry, condensers, heat exchangers, chemical industry, etc.

There are several tests conducted on SS 304H Flanges just to check the quality of the product. The tests that are done are like mechanical testing (tensile tests), Positive material identification tests, chemical testing (Spectro analysis), toughness tests, etc. The documents that along with the product we provide
