During steel plate and long-product production, numerous imperfections and defects appear that deteriorate product quality and consequently reduce revenue. The purpose of this paper is to provide a practical overview of typical defects (surface and internal) that occur and their root causes.,The data presented here derive from the quality department and from more than 50 technical reports of Stainless steel defects.ppt - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online.

The phenomenon starts with the necking of the material cross-section and, finally, material failure. Necking is the reduction of cross-sectional area under tensile load. The failure occurs when the material section reaches the least cross-section. Steel is one of the most widely building materials of modern times. Automatic detection of manufacturing defects in steel surfaces is a very important step for product quality control in the steel manufacturing industry. Traditional inspection systems require high SCI P185 Guidance notes on best practice in steel bridge construction 3.06/3 GN306R3 Revision 3 Safety note The area of attachment of lifting lugs should always be checked for sub-surface defects, whether the material is plate or a section.

Defects in steel products or any other SEM analysis on steel or refractory products were analyzed using a JEOL JSM-6490LV SEM with an EDAX detector. Figure 2. Examples of foreign material detected on the surface of the steel samples that are Casting Defects - Sand Mold, Metal Casting Introducing various metal casting defects with many pictures by Dandong Foundry in China. These are the common sand casting defects on the surface and inside of cast iron and cast steel parts. 1. Blowhole is a kind of cavities defect, which is also divided into pinhole and subs urface blowhole. Abstract. Steel defect diagnostics is important for industry task as it is tied to the product quality and production efficiency. The aim of this paper is evaluating the application of residual neural networks for recognition of industrial steel defects of three classes. Developed and investigated models based on deep residual neural networks for the recognition and classification of surface the steel. The so-called seams are surface defects that can be originated during cold drawing and they are constituted by longitudinal scratches or folds in the material. Several other surface defects (such as scratches and die marks) also can be caused by improper selection of the process parameters, i.e. poor lubrication or poor die condition Defects of low-carbon engineering steels 18Kh2N4MA, 25Kh2N4MA, 25G2S2N2MA reducing the operating life of components are studied. The most common metallurgical processing defects are: non-metallic inclusions, structur
