Adinox Overseas has been a major producer and exporter of high grade Stainless Steel 304H Flanges that are supremely strong, and have excellent properties as far as resistance in high temperature conditions are concerned. These flanges are manufactured to ASTM A182 F304H and have the universal standard UNS S30409. Having very great metallurgical properties, SS 304H flanges are commonly seen in many industries like petrochemical industry, heat exchanger, oil and gas industries as also power generation industry.
The Stainless steel 304H is a high carbon type of 304 that offers greater resistance to creep life and at high temperatures it also offers greater strength. The elevated carbon level which is usually 0.04 0.10% enables the flanges to have stability and structural strength under severe temperature conditions in areas where there is constant exposure to temperatures exceeding 5000C thus making it a good choice of application.
Adinox Overseas provides ASTM A182 F304H flanges who comes in a variety of types that include Slip-on, socket weld, blind, and weld neck, and threaded and lap joint, which are designed to serve different key operational requirements.
Among the most important features of UNS S30409 flanges, high corrosion resistance should be mentioned. Such flanges have a high level of resistance to oxidising agents and corrosive compounds, where longer service life periods and low maintenance expenditures are observed in severe working conditions. Moreover, Stainless Steel 304H flanges possess the versatility that is unsurpassable due to the austenitic structure that will enable them to remain strong even in cryogenic operations.
