Spanish to English Tech/Engineering Nuclear Eng/Sci

I'd just like to double-check the accuracy on this one. On a specification for parts for a nuclear power plant, the section regarding how the parts are to be identified.

Is "low-impact stamping" correct? I want to make sure this is accurately conveyed.

Context:
Los caracteres de todos los métodos de marcado se aplicarán de forma coherente y legible y con buena apariencia.
El método de marcaje preferido es el de estampado de bajo impacto.

Thanks in advance.
