Didn't you say it was 100% crack controlled?

We thought of addressing one of the questions asked after experiencing a problem related to surface discontinuities / errors, which is frequently encountered in the field of steel bars, as a topic.

To begin with, briefly talking about the terms "discontinuity" and "error" will be useful for the next steps. Any finding on the surface of the material that moves inward from the surface and disrupts the continuous form of the surface is called a discontinuity. Permissible surface discontinuity depth definitions are made according to the material size in the relevant standards. Findings that exceed the allowable surface discontinuity depth limits, that is, are deeper, are called surface defects. For surface defects, there are limits in the relevant standards for the rate of defective materials that may be encountered in the shipment batch, according to the surface quality class agreed upon at the time of ordering.
