Talking about the Stainless Steel 347/347H Tubes and the other products of this grade, they are stabilised and austenitic chromium steel alloys containing good amount of columbium that helps the products to eliminate the existence of carbide precipitation, along with removing away the intergranual corrosion. This alloy is largely stabilised through the added tantalum and chromium which offers the product with greater stress rupture and higher creep properties which you might not find in other metals as much as you get in here.
Our SS 347/347H Tubes are also composed of this fantastic grade of stainless steel which is largely seen deployed in the fabrication process of various equipments. These are the tubes which are usually placed in service in the situations where severe corrosion is experienced, this is thus, largely utilised by the petroleum refining industries. Some major industries which continuously make the use of these tubes include chemical processes, heat exchangers, temperature steam services, pressure steam pipes, radiant superheater, boiler tubes, and general refinery and in heavy duty exhaust systems too.
The major standards which our tubes confirms to, includes ASTM/ASME: UNS S34700 / S34709. So all of the corrosion resistance is one thing which our tubes get from the addition of columbium, thus it produces even superior level of resistance than what is produced by the 321 grade. We have got all the products designed and tested from specified procedures and thus, each of your purchase is a benchmark in its own. Stainless Steel 347/347H Tubes are actually designed for every industrialist!
