30CrNiMo8 (1.6580) belongs to the European standard alloy structural steel, and the implementation standard is: EN 10083-3-2006?
30CrNiMo8 has a tempered sorbite structure and a normalized pearlite structure.
Tempered sorbite is formed when martensite is tempered at high temperature (500℃-600℃). It can only be distinguished under an optical metallographic microscope by magnifying 500 to 600 times. , which is a composite structure in which carbide (including cementite) pellets are distributed in the matrix ferrite.
Tempered sorbite refers to tempering quenched steel at 450-600°C, and the resulting troostite is called tempered sorbite. It refers to the complex phase structure in which martensite is tempered at high temperature at 500~650℃ to form a complex structure with fine and uniform carbide particles and small spherical carbides (including cementite) distributed in the ferrite matrix. It is also a tempered structure of martensite, which is a mixture of ferrite and granular carbides. At this time, the ferrite has basically no carbon supersaturation, and the carbides are also stable carbides. It is a balanced structure at normal temperature
30CrNiMo8 (1.6580) is generally smelted by electric arc furnaces and oxygen top-blown converters. For those with high requirements, out-of-furnace refining, electroslag remelting or vacuum treatment, vacuum induction furnace smelting or Double vacuum smelting and appropriate heat treatment, 30CrNiMo8 is a material that is difficult to process. It is very difficult for 30CrNiMo8 to reach HRB80 or below. Generally, it is enough to reach HRB85 or so.
The chemical composition of 30CrNiMo8 (1.6580) is as follows:

The most advanced one you mentioned should be slightly lower than this
The specific number depends on how advanced the equipment is. It is probably difficult to know
