Technical characteristics

Stainless chrome steel 90Х18МФ are manufactured in accordance with GOST: 5949−75 and 5632−72 and specifications: 14−1-4628−89 and 14−1-1848−75. Steel 90Х18МФ made varietal and strip rolled by forging or rolling. Hot deformation is performed at a temperature 1130−950°C, followed by aging at a temperature of 750 °C and cooled. This steel alloy in the hardened state is used in chemical industry, manufacture of pumps, cutting tools, food or medical industry. The price is the best in this segment of the rental.

Production

This steel grade belongs to the class of martensitic alloys. Smelted in open induction and electric arc furnaces and in vacuum-induction furnaces with a final vacuum arc remelting. Plastic deformation is carried out in the temperature range 1100−900°C. the billets are produced by wire drawing, and sheet — rolling. In the case of rapid cooling, the formation of cracks. The temperature of hardening steel 1045 °C and t° leave 200 °C. Annealing hardens the material as a result of the martensitic transformation. The structure of granular perlite gives the annealing, after quenching the hardness of steel is 197−207 HB-1. The increase in the quenching temperature increases the proportion of residual austenite, the optimum hardness is achieved at 1050 °C.

Physical properties (20°C)

— Magnetic permeability in a field of 500 e равна1,255 micro Tesla/m.

The corrosion rate

— in moist ammonia and hydrogen sulfide atmosphere up to 0.005 mm/year;

— in solution H2 S2 at saturation 2.5 g/liter — to 0,0135 mm/year;

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

— in a mixture of aliphatic hydrocarbons (t° 20−90°C) — 0.003 mm/year.

Use

By forging or rolling produce varietal and flat steel, which is used in medical and food industry. In the hardened state steel is used in the manufacture of chemical valves, multi-threaded gear pumps designed for metering rest on the preparation of media in the production of cutting tools (according to GOST R 50 328.1−92). Products made from this steel meet the highest requirements for corrosion resistance and able to withstand repeated heat treatment, which is important for medical instruments. You can process them in the washing machines, they do not lose their properties in chlorinated water.
