Inspection items
Chemical Composition Analysis
– 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
– 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
– 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
– 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.
Heat Treatment
– 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
– 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
– 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
– Checks for surface scratches, pits, oxide scale, welding defects, etc.
– The aim is to identify obvious surface defects or processing issues.
Customized Testing
– 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.

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.
Show more +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.
Show more +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.
Show more +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.

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.
Show more +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.
