ASTM A312 / A358 Stainless Steel 347 Pipes Suppliers, 347 / 347H Stainless Steel Seamless Pipes, Call Us To Get ASME SA312 347 stainless steel Pipe
Stainless Steel 347 pipes are fabricated using the type 304 grade of basic austenitic alloys with added components like columbium. This addition of columbium enhance resistance from carbide precipitation and give protection against Intergranular corrosion. This chromium moly austenitic alloy possesses better welding and forming quality and improved toughness and works best even in cryogenic conditions. Unlike 304 grade steel, the 347 grade of alloy has better creep strength and rapture properties. It also works best in extreme heat conditions and has an excellent high pressure bearing capacity. The metal has better toughness along with good overall strength.

AISI 347 Stainless Steel Pipe
Stainless Steel 347 Seamless Pipe
Exhibiting to the chemical properties, it is seen that the metal is built from chromium and molybdenum. It also contains columbium, which makes the metal anticorrosive in nature with resistance from various crevice corrosion. While the other chemical components are similar to 304 grade of stainless steel. Its also has similar mechanical components, where the yield strength is 205 MPa and tensile strength is 515 MPa. This pipe is fabricated in various thicknesses ranging from 0.4mm to 30mm and has sizes ranging from 1/8” to 48”. It is formed in welded and seamless design and comes in round, rectangular and square shape.
Type 347 grade of stainless steel pipes are supplied to various sectors and has huge industrial applications like power generation, heat exchangers, condensers, chemical industry, pharmaceutical, petrochemicals, water supply system, oil and gas refineries, pulp and paper industry, food processing, and many more
