Steel Testing Laboratory from Grand Steel Products

At Grand Steel Products, we have an on-site (3rd party) Steel Testing Laboratory (STL) that performs mechanical and chemical testing to provide customers with the data and information necessary to meet specific steel application needs. As a customer, you can be assured that all testing done in our STL is handled by highly skilled technicians with high levels of expertise and experience with testing equipment. Our technicians perform precise technical calibrations of the testing equipment daily to be certain that all test data is highly accurate and precise. The STL offers complete services to our customers with low or high-volume testing needs. With customers all over the country, we provide expeditious service by overnight courier and local pick-up. Test results are promptly provided generally within hours.

Brinell Sun-Tec (Hardness Test Method)

The Brinell Sun-Tec Hardness Test Method was specifically created to specialize in testing the hardness of steel. It is used as a substitute device when the materials that are being tested are either coarse or have a surface that may be considered rougher compared to others. Data collection gathered by this instrument is done by using a steel ball indenter that is carefully pressed against the material under a certain amount of force. The force that is pushed against the material is deepened upon the actual hardness of the steel.  Once the indentation has taken place in the steel, it is quickly measured, and the Brinell measurements are based on the diameter. The data gathered from the measurements are then processed in the BHN formula, and the results are guaranteed to be accurate.

Double Olsen (Test Ductility)

The Double Olsen (Test Ductility) was designed to test the metal’s endurance and ability to withstand the tensile stress applied to the sample. It also records the coating weight, the thickness of the film, and the strength of the steel. The Double Olsen (Test Ductility) is very essential in testing. It notifies the tester of various key components that typically cannot be identified to the human eye. This machine expands on the capability of the materials and informs the tester what it will and will not allow the person operating the machine to do. The endurance of how the steel can be stretched without being stressed, weakened, or broken is the essential task of this model.

Instron (YTE Results)

The Instron device specializes in running a tensile also known as a tension test. This product also develops the yielding tensile elongation results. When properly conducting the tension test, it will inform the tester of the strength of the product being tested, how long the width of the sample will extend before splitting in half, and it will help determine what the material will yield and tensile strength. Elastic deformation is found after the stress is removed and the sample returns to its usual state before the load was initially applied. Elongation is also gathered from this product during testing.

ARL Fisons 3460 AES (Metal Analyzer)

ARL Fisons 3460 AES was issued to determine the composition of the steel that is being tested. During this process, an analysis is conducted to determine if the results align with the requirements of the metal processing companies and foundries being serviced at that time. After receiving the results, a solution is listed immediately and recommended to lower the potential cost. This machine was designed to record accurate calibrations and is equipped with a matrix effect system. This system was assembled to notify the tester if, by any chance, the specimen that is being analyzed is unequally calibrated and runs a spectral interference for accurate results.
