Product Introduction
Testing Scope
Applicable materials: Suitable for various types of free cutting structural steels such as sulfur based, lead based, calcium based, and composite free cutting elements.
Applicable objects: including easy cutting steel bars, wires, plates, profiles, forgings, and machined parts.
Applicable states: including different supply and processing states such as hot rolling and annealing.
Testing purpose: Used for incoming inspection of free cutting steel, chemical composition review, grade determination, production quality control, and failure analysis.
Test Item
Main element content detection: Determine the content of key alloys and free cutting elements such as carbon, silicon, manganese, sulfur, phosphorus, lead, calcium, etc. in free cutting steel.
Impurity element detection: detect residual harmful impurity elements such as copper, nickel, aluminum, etc.
Composition conformity assessment: Compare the standard requirements to determine whether the chemical composition meets the corresponding grade of free cutting steel indicators.
Grade assisted identification: Based on the measured composition, confirm the specific grade of free cutting steel.
