Product Introduction

Testing Scope
Applicable materials: Suitable for various types of bearing steel materials such as high carbon chromium bearing steel, carburized bearing steel, stainless bearing steel, and high-temperature bearing steel.
Applicable objects: including bearing steel bars, wires, pipes, plates, forgings, as well as bearing components such as bearing rings and rolling elements.
Applicable states: including different processing and heat treatment states such as hot rolling, annealing, quenching, tempering, etc.
Testing purpose: Used for incoming material acceptance of bearing steel, chemical composition review, material grade determination, production quality control, and failure analysis.
Test Item
Main element content detection: Determine the content of key alloy elements such as carbon, chromium, silicon, manganese, molybdenum, nickel, etc. in bearing steel.
Impurity element detection: detect the content of harmful and residual impurity elements such as sulfur, phosphorus, oxygen, copper, aluminum, etc.
Composition conformity assessment: Compare the standard requirements to determine whether the chemical composition meets the corresponding grade of bearing steel indicators.
Grade assisted identification: Based on the measured composition, confirm the specific grade of bearing steel.
