The impact test of the Austenitic Stainless Steel Seamless Tube refers to a test to detect the impact strength of stainless steel tubes. Use test equipment to break the sample. And according to the energy absorbed when the sample is broken to detect the ability of the material to resist impact damage, that is, to detect the brittleness and toughness of the material. The stronger the impact resistance of the stainless steel pipe, the greater the value, which is common sense.

Use a pendulum of a certain weight to impact the sample from a specified height. The energy absorbed when the stainless steel tube sample is broken is the absorption work. Its size is calculated according to the height reached by inertia after the pendulum breaks the sample. There is also an Izod impact testing machine, its sample and test method are different from the Charpy testing machine, it is rarely used in Japan. Some people think that this kind of experiment does not make much sense.
