Product Introduction

Scope of inspection
Applicable materials: Suitable for various types of steel such as carbon steel, alloy steel, bearing steel, tool steel, spring steel, stainless steel, gear steel, etc.
Applicable products: including steel bars, plates, wires, pipes, forgings, rolled materials, castings, and machined parts.
Inspection purpose: Used for steel incoming acceptance, production process quality control, smelting and rolling process verification, product performance evaluation, and failure analysis.
Inspection Item
Inclusion type assessment: Classify sulfides, oxides, silicates, spherical oxides, and other types based on their morphology and composition.
Inclusion grade assessment: Grade assessment of coarse and fine inclusions based on standard spectra.
Inclusion morphology detection: observe the shape, size, continuity, and distribution uniformity of inclusions.
Assessment of Inclusion Quantity: Determine the content and density of inclusions per unit area.
Harmful inclusion inspection: Identify abnormal inclusions such as coarse, sharp, and chain like inclusions that pose a significant threat to the performance of steel.
