Product Introduction

Scope of inspection
Applicable materials: Suitable for various types of steel plates with ferrite as the main matrix, such as carbon structural steel plates, low-alloy high-strength steel plates, high-quality carbon steel plates, and alloy structural steel plates.
Applicable states: steel plates in different heat treatment states, including hot rolling, cold rolling, annealing, normalizing, quenching and tempering.
Inspection location: Suitable for metallographic specimens of transverse and longitudinal sections of steel plates, used for evaluating grain uniformity and grain size grade.
Inspection purpose: Used for steel plate factory acceptance, rolling and heat treatment process verification, mechanical property matching evaluation, quality control and failure analysis.
Inspection Item
Evaluation of average grain size of ferrite: Determine and evaluate the grade of ferrite grain size according to the standard spectrum method.
Grain uniformity testing: Check whether the grain size is uniform, and determine whether there are mixed grains, abnormally coarse or fine grains.
Observation of ferrite grain morphology: Observe grain shape, grain boundary clarity, and distribution characteristics.
Accompanying organizational examination: Check for the presence of banded structures, pearlite distribution, and other factors that affect grain size assessment.
