Ding Testing Inspection: Ferrite Grain Size Determination, Guarding the Fine Microstructure of Metallic Materials
Ferrite grain size determination is a metallographic testing technique used to measure the size of ferrite grains, which is of great significance in evaluating the mechanical and processing properties of metallic materials. Ding Testing Inspection provides ferrite grain size determination services, professionally measuring the grain size of metals such as low carbon steel to assess and optimize the mechanical properties of materials.
Service Introduction
The measurement of ferrite grain size is generally conducted using two methods: the comparison method and the intercept method, with the comparison method being commonly used and the intercept method used for arbitration. The comparison method involves selecting representative fields of view and comparing them with standard rating diagrams, choosing the standard rating diagram level that is close to the tested image. The intercept method calculates the number of intercepts where the measurement grid intersects and is tangent to the grain boundaries, and then calculates the grain size level according to the corresponding formula.
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.
Service Scope
Ding Testing Inspection's service scope is extensive, covering ferrite grain size determination, including but not limited to:
The service scope mainly includes the determination of ferrite grain size in low carbon steel cold-rolled thin plates with a carbon content of less than 0.2%, and other metallic materials with grain shapes similar to the standard series rating diagrams.
Application Fields
Ding Testing Inspection's ferrite grain size services are widely used in the following industries:
Suitable for determining the ferrite grain size in low carbon steel cold-rolled thin plates with a carbon content of less than 0.2%, and other metallic materials with grain shapes similar to the standard series rating diagrams.
