We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.

 

ASTM A312 TP347H is an austenitic stainless steel. It has chromium and nickel content which give it the corrosion resistant properties. For extra toughness, the A312 347H material has higher carbon content. The addition of more carbon causes toughness but is also less strong than the low carbon version of the same material. But to overcome the issue, columbium is added in the A312 TP347H material. The alloy composition makes the material resistant to most oxidizing agents. Regardless of the high carbon content, the A312 TP347H material has excellent resistance to intergranular corrosion. This makes the 347H Stainless Steel Pipe be applied in applications that operate under high temperatures with high risk of oxidization. The SS 347H Seamless Pipe material is cold drawn and therefore cannot be hardened by heat treatment. But it could be hardened by cold working. The material could also be easily welded upon.

Why 347h SS is used for Chemical Processing?

The grade 347 is specific austenitic stainless steel made for repeated intermittent exposure to temperatures above 800 degrees Celsius. These are modifications of 304 stainless steel. They are similar to the 321 grade in some mechanical properties but different in that it has columbium in the composition. The material is corrosion resistant to most corrosive media in medium to high temperatures.

 

This is an important aspect required at chemical processing. The material has minimum yield strength of 205MPa and the minimum tensile strength at 515MPa. This allows the material to withstand high pressure at temperatures above 850 degrees Celsius. The pipes and components also have a good elongation and high hardness. The 304 material can undergo intergranular corrosion above temperatures 850 F. The 347H has a higher carbon content and heat resistant so that it can perform in this temperature range.

 

The combination of the pressure containment capacities, the strength, hardness, heat resistance and corrosion resistance make it applicable for chemical processing. These properties also make the material used in other high corrosive, high heat applications such as the boiler tubes and casings, radiant super heaters, heat exchanger tubes, oil and gas refineries and aircraft exhaust stacks.
