• Choose the proper hardness testing method for different inner diameters

    Stainless steel pipe and Stainless Steel Tube is a commonly used material, and it is widely used in equipment and mechanical parts that require good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel. Stainless steel seamless pipes are produced in accordance with ASTM A312 and Stainless Steel Tubes are produced according to ASTM A213 / ASME SA213 When the inner diameter of the stainless steel pipe is greater than 26mm, the hardness of the inner wall of the pipe can be tested with a Rockwell or surface Rockwell hardness tester. The solution annealed stainless steel pipe with the inner diameter of the stainless steel tube above 6.0mm and the wall thickness below 13mm can use the W-B75 Webster hardness tester, which is very fast and easy to test, and…

  • Hardness testing method for different inner diameters of stainless steel pipes

    Stainless steel pipe is a kind of universal stainless steel, which is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel. Stainless steel seamless pipe is a grade of stainless steel produced in accordance with the American ASTM standard. When the inner diameter of the stainless steel pipe is greater than 26mm, the hardness of the inner wall of the pipe can also be tested with a Rockwell or surface Rockwell hardness tester. For stainless steel pipes with inner diameter above 6.0mm and wall thickness below 13mm, the W-B75 Webster hardness tester can be used. It is very fast and easy to test and is suitable for quick and non-destructive qualification inspection of stainless steel pipes. For stainless steel pipes…

    Stainless steel thickness greater than 1.2mm, with Rockwell hardness tester, testing, HRB, HRC hardness. 0.2 ~ 1.2mm thickness stainless steel capillary pipe plate surface Rockwell hardness test HRT, HRN hardness. Less than 0.2mm thick stainless steel plate surface Luo Hardness tester with diamond anvil, test HR30Tm hardness. Metal materials in the United States, the standard in on the hardness test has a prominent feature is the precedence Rockwell hardness test, supplemented by Brinell hardness test, Vickers hardness test uses very little the U.S. believes Vickers hardness test primarily. The research for metal and thin small parts test. Chinese and Japanese standards are also used three types of hardness test, users can thickness and the material conditions of state and choose one of their own to test the stainless steel pipe material. Japanese stainless steel capillary pipe on the tensile strength test and hardness test requirements and the corresponding Chinese standard forms the same value close to the Chinese standard reference here to see the traces by…

The Rockwell B values are superimposed on this table using an approximation from ASTM E140 Table5, which compares Rockwell B and Brinell. For the indentation methods the different measurements in HV, HRC and HB can also be compared without too much of insecurity. However, for the rebounding methods like Shore and Equotip the errors when making conversions are larger as the individual measurements are highly…
