1. Material certificate of 42CrMo seamless pipe.
For each batch of 42CrMo seamless pipe, the manufacturer will provide the material certificate when arranging delivery, which will mark the relevant information of 42CrMo seamless pipe, furnace batch number, chemical composition, mechanical properties, etc. The true and false quality can be judged by the material certificate of 42CrMo seamless pipe purchased.

2. Identification of chemical constituents of 42CrMo seamless pipe.
If the material certificate of 42CrMo seamless pipe is true after analysis, it is necessary to analyze the chemical composition of 42CrMo seamless pipe, because it is difficult to distinguish what kind of material it is from the appearance of seamless pipe, that is to say, it is necessary to take samples of this batch of 42CrMo seamless pipes to professional institutions for chemical composition analysis.

The chemical composition of 42CrMo seamless pipe is as follows: C: 0.38-0.45; Si: 0.17-0.37; Mn: 0.50-0.80; Mo: 0.15-0.25; Cr: 0.90-1.20. Identification agency, will give you the conclusion.

Is 42CrMo seamless pipe true? In fact, the above are the measures you can take if you don't trust your downstream suppliers. Of course, to avoid the complicated procedures, finding a reliable 42CrMo seamless pipe supplier is the most basic way.
