SS 316 Stainless Steel Tube/ASTM 304 201 stainless steel Pipe from China factory
The inner diameter of stainless steel pipe is more than 6.0mm, and the wall thickness is less than 13mm. The annealed stainless steel pipe can be tested by W-B75 Type Wechsler hardness tester. It is very fast and simple, and suitable for rapid and nondestructive inspection of stainless steel pipe. Stainless steel pipe inner diameter is greater than 30mm, wall thickness is greater than 1.2mm stainless steel pipe, rockwell hardness tester, test HRB, HRC hardness. Stainless steel tubes with inner diameter greater than 30mm and wall thickness less than 1.2mm were tested for HRT or HRN hardness by surface Rockwell hardness tester. For stainless steel pipes with inner diameter less than 0mm and greater than 4.8mm, rockwell hardness tester is used to test HR15T hardness. When the inner diameter of stainless steel pipe is greater than 26mm, you can also use Rockwell or surface Rockwell hardness tester to test the hardness of the inner wall of the pipe.
