Chemical Composition Analysis of Coal Mill Gear Material

A more detailed chemical composition analysis of the gear material sent for inspection is performed based on the spectral analysis method.The test results are shown in the table.The table also lists the standard compositions of 42CrMoA steel in the national standard GB/T 3077-2015 Alloy Structural Steel for comparison.

The results show that the chemical composition of the sun gear material conforms to the national standard and belongs to 42CrMoA high-quality alloy structural steel, which is in conformity with the data provided.
