According to GOST R 51394-99, GOST 31622-2012 the chemical composition is given for steel grade 03H18N16M3 (ZI133). Mass fractions of chromium and molybdenum in steel should satisfy the condition: 3% Mo +% Cr ≥26. Magnesium (not more than 0.030%) and aluminum (no more than 0.25%) as technological additives are introduced into the metal by calculation and chemical analysis is not determined. Deviation by mass fraction of silicon plus 0.40% is allowed. Permissible deviations of the chemical composition of finished rolled products are in accordance with GOST 5632.
According to TU 14-123-134-95 the chemical composition is given for steel grade 03H18N16M3-VD (ZI133-VD).

Technological properties

Name The value
Macrostructure and contamination The macrostructure of a rental must not have residues of shrinkage, delamination, foreign metal and non-metallic inclusions, cracks and bubbles that are visible without using the magnifying devices. The sections of the sheets should be free of cracks, splits and delamination. Pollution steel non-metallic inclusions shall not exceed sulphides, aluminates, silicates and globular oxides 1,5 points for each parameter for thin series and score 1.0 - for thick series.
Microstructure In the microstructure of steel long products should not be ferritic phase. The content of ferritic phase in the microstructure of steel sheet metal should not exceed the point 1. Austenitic grain should not be larger than 4-th number.
Corrosion resistance Rental in the state of delivery must be resistant to intergranular corrosion.
