Description

Alloy 03Х20Н45М4БРЦ used: for the production of forged billets used for the manufacture of extremely thin-walled pipes of high precision; parts of shells of fuel elements for transport and stationary nuclear power plants.

Note

The alloy austenitic. The alloy has a greater resistance to low-temperature radiation embrittlement, radiation swelling, radiation creep, corrosion damage in comparison with steel 03KH16N15M3B.

Macrostructure and contamination On the other 14-1-1903-77 macrostructure of the alloy on the cross etched templeto should not be visible to the naked eye: podnasadochnogo looseness, cracks, slag inclusions, crusts, delamination and subcortical bubbles. The Central porosity, point heterogeneity (total porosity) and segregated square in the delivered profile should not exceed 1 score. On the outer surface of a tube blank as supplied must not be cracked, shells, shells, sunsets (zakonov), wooloowin, pesochin, delaminations, inclusions, visible without using the magnifying devices. Contamination of metal non-metallic inclusions is evaluated by the maximum score should be: - stroke OS oxides ≤ 1.0 points; a point FROM oxides ≤ 1.0 points; - silicates fragile CX ≤ 1.0 points; - silicates plastic SP ≤ 1.0 points; - silicates, non-deformed SN ≤ 1.0 points; sulfide ≤ 1.0 points; - carbonitrides, nitrides, NS, NT ≤ 3.0 points.
Corrosion resistance Arbitration test susceptibility to intergranular attack produced by the method AM GOST 6032 (test duration 24 hours) with provotsiruet by heating at a temperature of 650 °C for 2 hours. The quenching temperature before precipitating heat of 1050 °C. the susceptibility to intercrystalline corrosion shall be tested three samples from a test ingot, batch - melting.
