SS 347, 347H Flanges Manufacturer, Supplier In Mumbai India

Alpha Overseas is a top manufacturer and supplier of SS 347 / 347H Flanges.
Alloy 347 is a columbium-containing stabilized austenitic chromium steel that enables the eradication of carbide precipitation and, as a result, intergranular corrosion. Alloy 347 offers stronger creep and stress rupture properties than alloys 304 and 304L, which may also be utilized for exposures where sensitization and intergranular corrosion are a problem. Alloy 347 is stabilized by the additions of chromium and tantalum. Alloy 347's outstanding corrosion resistance, which is even better than that of alloy 321 because of the addition of columbium, is another benefit. 347H, the higher carbon composition form of Alloy 347, also exhibits improved high temperature and creep capabilities.

Table Of Contents

The manufacturing of equipment that must be put into service under highly corrosive conditions and the petroleum refining sectors both regularly use alloy 347.
SS 347 / 347H Flange provides comparable general, overall corrosion resistance to alloy 304. SS 347 / 347H Flanges are used in settings where intergranular corrosion concerns alloys like Alloy 304. SS 347 / 347H Flanges are used most frequently for large welded equipment that cannot be annealed and for machinery that is operated between 800 and 150°F (427 to 816°C). For aqueous and other low-temperature conditions, Alloy 347 is favoured over Alloy 321. SS 347 / 347H Flanges are employed mostly in high-temperature situations where resistance to sensitization is required, preventing lower levels of intergranular corrosion. SS 347 / 347H Flanges are similar to all other 18-8 austenitic stainless steels in terms of oxidation resistance.
