Many salesmen who purchase Stainless Steel Balls may not be very professional about steel balls. Today we will focus on how to judge the quality of stainless steel beads:
If you don't have professional testing equipment, you can pass the most direct method, that is, the naked eye observation method, that is, to see the brightness of the steel ball, whether the surface is rough, whether there is pitting, whether there is a flat head, whether it is cracked.
If there is a testing device, the composition of the material can be tested first, and the accuracy of the steel ball is measured: the precision of the stainless steel bead is divided into roundness, surface roughness, gauge value, tolerance. In addition, the hardness of the stainless steel ball can be detected, and the vibration level can be measured by the high level requirement.
