WHAT IS STAINLESS STEEL 347?

Stainless steel 347 is a super allow with special properties that can be used in various industries. It is an austenitic, stabilized, chromium steel that contains an element known as columbium which is the main ingredients behind the elimination of carbide precipitation, and, consequently, intergranular corrosion.

The steel of this type is recommended for use under high-pressure and high-temperature areas. They are recommended for parts fabricated by welding which cannot be subsequently annealed. It shows reduced tendencies to form continuous networks of chromium carbides at the grain boundaries. Stainless steel 347 is used for parts that are heated and cooled continuously to temperatures between 800°F and 1600°F.

The stainless steel of this grade, in general, provides superior intergranular corrosion resistance due to stabilization using columbium. The alloy is useful under high temperature and can provide service continuously for a maximum temperature of up to 1650°F. It thus has better high-temperature properties than stainless steel of type 304 or 304.

On adding chromium and tantalum to Stainless steel 347, it can be stabilized and higher creep and stress rupture properties can be achieved than alloy 304 and 304L. For obtaining resistance to corrosion that is even higher than that of alloy 321, columbium can be added to stainless steel 347. Stainless steel 347H is a modified version of Alloy 347 that has higher carbon composition and shows enhanced high temperature and creep properties.

INTRODUCTION ABOUT STAINLESS STEEL 347 PIPES

Stainless Steel 347 Pipes are widely used in various industries due to their ability to withstand corrosion. The pipes of this grade are in high demand due to their superb characteristics. The pipes serve the purpose of fabrication of equipments that are placed for work under severe corrosive conditions and are also common to the petroleum refining industries.

The pipes of this grade are suitable for use in environments with high temperature such as in high-temperature chemical process, steam services and radiant super heaters. Stainless steel 347 pipes are also used in refineries and as a part of Heavy duty exhaust systems. General refinery piping consists of this very grade of stainless steel.
