Ding Testing Inspection: Non-metallic Inclusion Testing, Safeguarding the Purity of Metallic Materials
Non-metallic inclusion testing is a metallographic analysis technique used to detect the content and distribution of non-metallic inclusions in metallic materials, which is crucial for assessing the mechanical and processing properties of materials. Ding Testing Inspection provides non-metallic inclusion testing services to professionally evaluate non-metallic inclusions in metallic materials, ensuring material quality and performance meet the high standards of industrial applications.
Service Introduction
Non-metallic inclusion testing involves detecting non-metallic phases in metals that are not part of the composition and performance requirements, further accurately measuring the quality of the metal's material. The study of non-metallic inclusions in steel has always been an important issue in steelmaking and continuous casting production, and inclusion analysis is an important indicator of steel quality, listed as one of the routine inspection items for the dispatch of high-quality steel. The presence of non-metallic inclusions in steel is inevitable, and steel inclusions are divided into two major categories: endogenous inclusions and exogenous inclusions.
Sample Grading
Metal inclusions are divided into five major categories: A, B, C, D, and DS, with A to D categories further divided into coarse and fine (based on diameter) for evaluation, using the letter 'e' to denote coarse inclusions. Each type of inclusion is graded from 0.5 to 3 levels, with a level difference of 0.5, totaling six grades.
Sample Classification
According to the chemical composition of inclusions, they can be classified into: oxide inclusions, sulfide inclusions, nitride inclusions, and silicate inclusions.
In production inspection, they are also classified based on the plasticity and distribution characteristics of inclusions: brittle inclusions, plastic inclusions, spherical non-deformable inclusions, and semi-plastic inclusions.
Industry Pain Points
The industry pain point is that non-metallic inclusions may lead to a decrease in material performance, such as reduced plasticity, toughness, weldability, and corrosion resistance, as well as causing fatigue fractures and heat brittleness issues, affecting the reliability and safety of products.
