| Macrostructure and contamination |
The macrostructure of the alloy when tested for cross etched templeto should not have cracks, slag inclusions, voids and traces of shrinkage of the shell. |
| Features of production |
Bars and rods, of alloy can be supplied under hot or under cold stamping, mechanical treatment, as specified in the order. On the surface of the bars under the hot stamping should not be captured, rolling rolled cracks, holes, sunsets and zakovou - local defects should be removed with gentle scraping. The depth of Stripping shall not exceed the tolerances for size, measured from face value. The ratio of the width of the Stripping depth should not be less than 6. No Stripping allowed some small risks and dents within half of the tolerance on size. On the surface of bars designed for cold mechanical processing is not allowed defects when their depth exceeds the tolerance size. Bars with a diameter or a side of a square of 80 mm or more are subject to ultrasonic inspection according to the method of the supplier. Rejection when UT is the presence of a defect, the amplitude of which is greater than or equal to the amplitude of the signal reflected from the flat end face of the control reflector with a diameter of 3.0 mm in the reference sample sensitivity located on the same (with a tolerance of -10 mm) or greater depth as the defect. |
