Stainless Steel 347 / 347H Seamless Pipe

347 stainless steel pipe is an excellent high-temperature oxidation-resistant stainless steel material. Its main chemical composition includes 17-19% chromium, 9-13% nickel and 0.08% carbon. In addition, it also contains small amounts of titanium, niobium, molybdenum and other elements.
In high-temperature environments, 347 stainless steel round pipes have excellent corrosion and oxidation resistance, making them widely used in chemical, petroleum, pharmaceutical and food processing industries. Compared with other stainless steel materials, 347 stainless steel pipes can maintain stability and durability for a longer period of time in high temperature environments and are not prone to embrittlement or fatigue.
In addition to high temperature environments, 347 acid-resistant stainless steel pipes also have excellent corrosion resistance. Its ability to maintain stable performance in corrosive environments such as strong acids and bases (such as chloride ions and sulfide ions) makes it very popular in the chemical and petroleum industries. The material's stability allows it to provide reliable long-term service in a variety of extreme environments, whether high temperatures or corrosive environments.
In short, 347 high temperature stainless steel pipe is a very excellent high temperature oxidation resistant stainless steel material with excellent corrosion resistance and high temperature stability. It has been widely used in many industries, providing reliable support for equipment and processes in various extreme environments.

Mechanical Properties of Stainless Steel 347/347H Tubes

Stainless Steel 347 Hollow Pipe

Hydraulic test: Conduct a hydraulic pressure test on the stainless steel seamless pipes one by one, and maintain the specified pressure value for no less than 5 seconds. Steel pipes must not leak or seep. The conventional supply hydraulic pressure test is P=2SR/D (maximum not exceeding 20MPa).
Corrosion Resistance: In applications requiring better resistance to general corrosion and pitting corrosion, 347 contains only 2-3% molybdenum, which is better than 304.
Process performance inspection: flattening test, tensile test, flaring test, hardness test, metallographic test, non-destructive testing (including eddy current testing and ultrasonic testing).
