Round Double Wall Stainless Spiral Pipe rockwell hardness test and brinell hardness test, are indentation test method.The difference is that it measures the depth of the indentation.Rockwell hardness test is a widely used method at present, in which HRC is only second to HB in steel tube standard.Rockwell hardness can be applied to the determination of extremely soft to extremely hard metal materials, it makes up for the brinell method is not, easier than brinell method, directly from the hardness machine dial to read the hardness value.However, due to its small indentation, so the hardness value is not as accurate as brinell method.
Round Double Wall Stainless Spiral Pipe is also a indentation test method and can be used to determine the hardness of very thin metallic materials and surface layers.It has the main advantages of brinell method and rockwell method, but overcomes their basic disadvantages.
