Steel 25ХГСНМА
Designation
Description
25ХГСНМА steel is used: for the production of hot-rolled steel by synthetic slag treatment and is intended for remelting in an induction furnace method of electroslag remelting in the production of the responsible castings for the aircraft industry.
Note
High strength steel construction high-quality, bromocinnamaldehyde.
Standards
Chemical composition
Fe is the basis.
According to TU 14-1-4325-87, the total mass fraction of sulfur and phosphorus should not exceed 0.024%. The following deviations from the norms of the chemical composition are permissible: manganese, silicon and nickel - plus 0.050% each, chromium and molybdenum - plus 0.030% each, phosphorus - plus 0.005%. The residual aluminum content is not more than 0.045%. The content of nitrogen is controlled in steel. The presence of tungsten to 0.20%, titanium to 0.030%, and vanadium to 0.050% is not a defect.
