The laboratories that are part of the Central Plant Laboratory conduct research, measurements, and tests at various stages of the strip's life cycle: from incoming inspection of charge materials to micron strip.

Composition of the Central Plant Laboratory:

Spectral Laboratory;

Mechanical Laboratory;

Physical and Metallographic Laboratory;

Linear-Angular Measurements Laboratory.

Spectral Laboratory

Types of tests: determination of the chemical composition of low-alloy, high-carbon steels and alloys, as well as those based on nickel, iron-cobalt, and iron.

Spectral Laboratory is engaged in determining the chemical composition of steels and alloys based on nickel, iron-cobalt, and iron. Quantitative content determination is carried out using optical emission and X-ray fluorescence spectrometers.

Mechanical Laboratory

The Mechanical Laboratory allows determining the mechanical properties of metals and alloys:

Strip Tensile Test:

Determination of tensile strength;
Determination of relative elongation;
Determination of yield strength;

Strip test for spherical indentation depth (Erichsen test) from 0.1 to 2 mm thick;

Strip Hardness Test:

Rockwell hardness measurement (HRB, HRC, HRN, theoretically HRT);
Vickers hardness measurement (HV5, HV10, HV30).

Physical and Metallographic Laboratory

The Physical and Metallographic Laboratory is engaged in studying the structure of samples and determining the magnetic properties of materials:

Determination of microhardness;

Quantity, size of non-metallic inclusions;

Presence and thickness of the decarburized layer;

Presence and thickness of the oxide layer;

Grain size;

Qualitative determination of phases (ferrite, cementite, austenite, martensite);

Determination of resistance to intergranular corrosion;

Determination of the ferrite phase;

Determination of the thermal coefficient of linear expansion;

Determination of magnetic properties (technical saturation induction, coercive force, permeability, rectangularity ratio);

Determination of specific losses;

Measurement of specific electrical resistance.

Linear-Angular Measurements Laboratory

The Linear-Angular Measurements Laboratory allows for accurate measurements of the geometric parameters of the strip to meet the requirements of GOSTs for finished products:

Strip thickness and width;

Scratch depth;

Surface roughness;

Sickle shape;

Groove shape;

Burr size.

(i)

All laboratory equipment undergoes periodic verification and certification; measurements are carried out in accordance with the requirements of GOSTs and Technical Specifications.
