ASTM E1077 Standard Test Methods for Estimating the Depth of Decarburization of Steel Specimens

The ASTM E1077 test method is used for the assessment of the extent of decarburization of steels regardless of their composition, matrix microstructure, and section shape. The ASTM E1077 test method identifies surface carbon content losses resulting from heating at elevated temperatures, such as during a hot working or heat treatment process. The defined test methods range from simple screening tests to extra statistically complex test methods depending on the examination's requirements.

    Introduction to ASTM E1077

    The ASTM E1077 test method is used to determine the usual or extreme depth of decarburization of hardened or non-hardened steel products. The results of the ASTM E1077 test can serve various purposes, including qualifying materials for shipment based on agreed criteria between the purchaser and manufacturer and evaluating the impact of processing along decarburization tendencies. In ASTM E1077, the chemical analytical methods assess the depth of decarburization. These techniques are usually applied for research purposes. The micro-indentation hardness method is appropriate for the accurate assessment of hardened structures with relatively homogeneous microstructures. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM E1077 tests for our clients.

    ASTM E1077 Test Method

    Measurement of decarburizationIn ASTM E1077, a short piece of material is heated and cut material of interest to detect the hardened specimen. Determination of carbon steel is performed. Samples are reserved at locations that represent the bulk specimen.
    Evaluation The variance between the surface hardness and the theoretical maximum hardness in the steel’s carbon content shows decarburization.

    ASTM E1077 Test Specimen

    Specimen DetailIn ASTM E1077, the test specimen is the piece of steel that is being tested and subjected to various processes.  
    Specimen SizeThe specimen size is 2.5 cm in diameter, for larger sections, more than one specimen is needed.

    ASTM E1077 Test Result

    In summary, the ASTM E1077 test method is used to identify alterations in the surface microstructure, hardness, or carbon content of steel sections caused by decarburization. The decarburization depth is defined as a point where a consistent microstructure, hardness, or carbon content is detected.

    ASTM E1077 Related Test

    The ASTM E1077 test method is related to ASTM E3, which is the preparation of metallographic specimens, and the ASTM E384, test method for micro indentation hardness of materials.
