How to detect the hardness of stainless steel sheet?

Stainless steel plate, high strength and hardness, good plasticity and toughness. According to the production method, it can be divided into two types: hot rolling and cold rolling. According to the structural characteristics of steel, it can be divided into five types. The stainless steel mesh industry is divided into 200 series, 300 series and 400 series stainless steel products. According to the manufacturing method, there are two kinds of hot rolling and cold rolling, including thin plates with a thickness of 0.5-4mm and thick plates with a thickness of 4.5-35mm.

How to detect the hardness of stainless steel plate? How much do you know about this? Here Topson will introduce you to this issue:

For annealed stainless steel plates with inner diameter greater than 6.0mm and wall thickness less than 13mm, w-B75 Webster hardness tester can be used.

For stainless steel plates with inner diameter greater than 30mm and wall thickness greater than 1.2mm, use Rockwell hardness tester to measure HRB and HRC hardness. The inner diameter of the stainless steel plate is greater than 30mm and the wall thickness is less than 1.2mm. The surface Rockwell hardness tester, HRT or HRN hardness test is used for the stainless steel plate. When the inner diameter of the stainless steel plate is greater than 26mm, the hardness of the inner wall of the tube can also be tested with a Rockwell hardness tester or a desktop Rockwell hardness tester.
