Technical characteristics

Stainless chrome steel 95X18 is made in accordance with the following GOST 5632−72; 5949−75 and 4405−75, as well as technical conditions: 14−1-4628−89 and 14−1-1848−75. This stainless alloy is produced varietal and flat steel by forging or rolling. Hot deformation is performed in temperature range from 1130 to 950 °C, followed by aging (temperature 750°C) and cooling. This steel alloy in the hardened state is used in the production of parts with high hardness: bushings, bearings, knives, etc.

This steel belongs to the class of martensitic alloys. It is smelted in open electric arc and induction furnaces and in vacuum-induction furnaces with subsequent vacuum arc remelting. The quality of the products of grade 95X18 normalized state standards. The quenching temperature 1045 °C, and t° leave 200 °C. After hardening is hardening as the result of the martensitic transformation, and the hardness reaches 197−207 HB-1. The increase in the quenching temperature increases the proportion of residual austenite. Optimum hardness is achieved by quenching temperature of 1050 °C. the Structure of granular pearlite gives steel annealing, Hot deformation is carried out in the temperature range 1130 — 950 °C. the blanks produced by rolling a varietal — drawing. In the process of rapid cooling, the formation of cracks.

The corrosion rate

— in humid atmosphere saturated NH3 and H2 S2, up to 0.005 mm/year;

-in solution, H2 S2, (saturation 2.5 g/l) — to 0,0135 mm/year;

— in an aqueous solution of NH3, the corrosion rate (t° 20 °C) to 0.006 mm/year; and at 90 °C — to 0,097 mm/year;

— in a mixture of aliphatic hydrocarbons (temperature 20−90°C) up to 0,003 mm/year;


This alloy is widely used in engineering and metallurgy. After hot deformation, followed by aging at a temperature of 750 °C and cooling is achieved by hardening, which allows to produce parts with high hardness: bushings, bearings, knives and other Products made from this steel meet the highest requirements for corrosion resistance, they are able to withstand repeated heat treatment that is necessary for medical instruments. You can process them in the washing machines, they do not lose their properties in chlorinated water.
