Stainless steel tube with Rockwell hardness test Brinell hardness test, are indentation test method. The difference is that Sichuan stainless steel pipe, which is a measure of the depth of the indentation. Rockwell hardness test is the current method of application is very wide, 304 stainless steel, which HRC Brinell hardness HB in use after the steel standards. Rockwell hardness is applicable to the determination by the extremely soft to extremely hard metal materials, which make up the Brinell method is not, and stainless steel pipe specifications, representing Brinell method is simple, 316l stainless steel pipe, can be read directly from the dial hardness hardness machine value. However, because of its small indentation, so not as good as Brinell hardness value method is accurate.
