Metal Material Testing

As a third-party testing organization with a professional metal material testing laboratory, we are dedicated to providing comprehensive metal property testing services.
Our testing engineers have years of experience and can tailor scientific and reasonable testing plans according to your needs. Our testing process is rigorous and fair, with complete equipment and precise instruments, resulting in reliable testing reports to support your business development.

The testing duration for metal materials

Metal material testing usually takes between 1 to 7 working days, but you can get it done faster with expedited services if needed. The testing engineer will decide the exact duration based on how complex the project is.

The cost of metal material testing

The cost of metal material testing depends on the type of project and how complex it is. The engineer will give you a quote based on your specific needs.

Inspection items

Chemical Composition Analysis

– This involves a quantitative analysis of elements in the steel, such as carbon (C), manganese (Mn), silicon (Si), molybdenum (Mo), chromium (Cr), nickel (Ni), cobalt (Co), etc., which significantly impact the steel’s performance.
– Methods used include atomic absorption spectrometers, X-ray fluorescence spectrometers, and inductively coupled plasma mass spectrometers.
– The purpose is to ensure that the chemical composition of the steel meets the specified standards, thus guaranteeing its final performance.

Mechanical Properties Testing

– Are you overly dependent on any single country or supplier?
 – Tests include:
     – Tensile strength
     – Yield strength
     – Elongation
     – Reduction in area
     – Hardness
     – Impact toughness
   – Methods used include tensile testing, impact testing, and hardness testing.
   – The purpose is to assess the material’s performance under different stresses to ensure it is suitable for specific applications.

Ultrasonic Testing

– Do you need on-the-ground support in global supply markets?
– Utilizes the propagation characteristics of ultrasound in materials to detect internal defects such as cracks, inclusions, and bubbles.
– The testing process includes transverse and longitudinal wave scanning of the material to assess its integrity.
– The aim is to identify and locate microdefects within the material




Structural Analysis

– Includes static and dynamic stress analysis, fatigue analysis, and fracture analysis.
– Methods used include finite element analysis (FEA), experimental stress analysis, and fatigue life prediction.
– The purpose is to evaluate the response and durability of structures under stress and to predict potential structural failures.

Isıl İşlem

– Inspects the microstructure and properties of the steel after heat treatment processes such as quenching, tempering, and normalizing.
– Includes metallographic analysis, hardness testing, and grain size assessment.
– The purpose is to verify that the heat treatment process has achieved the intended performance goals.

Magnetic Particle Testing

– Uses magnetic powder to detect surface and near-surface defects such as cracks in magnetic materials.
– The process includes magnetizing the workpiece, applying magnetic powder, and observing the accumulation of powder.
– The aim is to find and mark surface and subsurface defects in magnetic materials.

Dimensional Testing

– Uses various measuring tools and devices (such as calipers, micrometers, and coordinate measuring machines) for precise measurement of the dimensions, shape, and position of parts.
– Testing includes linear dimensions, geometric tolerance, threads, gears, etc.
– The purpose is to confirm that the product dimensions meet the design drawings and engineering requirements.

Visual Testing

– Conducts a visual inspection of the material’s surface with or without the aid of magnifying glasses, cameras, or other auxiliary tools.
– Checks for surface scratches, pits, oxide scale, welding defects, etc.
– The aim is to identify obvious surface defects or processing issues.

Customized Testing

– Unique tests conducted according to specific customer needs or industry standards.
– Can include special corrosion testing, environmental adaptability testing, or performance testing for specific applications.
– The purpose is to ensure that the material or product meets specific application requirements or customer specifications.

Process of metal material testing report

Communicate with engineers to determine the requirements for metal material testing
Have the commissioning units fill out the testing commissioning order and confirm payment
Send the samples, conduct laboratory testing, and issue testing results
Based on the testing content, generate the metal material testing report
Send the report and provide after-sales value-added services

Validity Period of Metal Material Inspection Report

In theory, the third-party test report for metal materials does not have a defined expiration period. If there are no changes in the material properties or updates to the testing standards, the report remains valid for an extended period. However, if there are any alterations to the content of the current report, it becomes necessary to redo the testing and obtain a new report. Additionally, the validity of the report can also be influenced by the requirements of the requesting party.

Steel Processing Services

We have advanced equipment and complete testing methods to ensure the quality of our products. Our equipment includes large digital direct-reading spectrometers, flaw detectors, hydrogen-oxygen-nitrogen analyzers, carbon-sulfur analyzers, servo universal testing machines, -60°C low-temperature impact testing machines, Zeiss microscopes, and other types of equipment to ensure that our products meet customer requirements.

Carbon / Sulfur Analyzer

ELTRA’s CS-2000 is the only analyzer on the market for the determination of carbon and sulfur in organic as well as inorganic samples.

For this purpose, the CS-2000 is equipped with both an induction and a resistance furnace covering the full range of carbon and sulfur analysis. The CS-2000 is available with up to four independent infrared cells, which allow the precise and simultaneous analysis of high and low carbon and/or sulfur concentrations. The sensitivity of the cells can be customized individually by selecting the length of the IR-paths to ensure the optimum measuring range for each application.

Hardness Test

Hardness measures the resistance of a sample to material deformation due to a constant compression load from a sharp object.

The tests work on the basic premise of measuring the critical dimensions of an indentation left by a specifically dimensioned and loaded indenter. We are measuring hardness on Rockwell, Vickers & Brinell scales.

Tensile Test

Tensile Test in which a sample is subjected to a controlled tension until failure.

The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under other types of forces. Properties that are directly measured via a tensile test are ultimate tensile strength, maximum elongation and reduction in area.

Impact Test

The purpose of impact testing is to measure an object’s ability to resist high-rate loading.

It is usually thought of in terms of two objects striking each other at high relative speeds. A part or material’s ability to resist impact often is one of the determining factors in the service life of a part, or in the suitability of a designated material for a particular application. Impact testing most commonly consists of Charpy and IZOD Specimen configurations.

Spectro Test

Take advantage of our tailored steel services.

We are performing spectro test on raw material heat, a lot forged and heat treated in single batch to establish that the manufactured product is in conformity with the specified chemical composition.

UT Test

Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested.

In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipe work corrosion.
