Technical characteristics

High-alloy stainless steel 15Х16К5Н2МВФАБ (EP 866) belongs to the group of high-strength corrosion-resistant martensitic steels. Due to its ideal blend of basic alloy components, cobalt, vanadium, tungsten is intended for the manufacture of shells and nozzles of space rockets, other aircraft, and also for heat-resistant elements, heating and melting furnaces, in particular, fasteners. Corrosion indicators are used in the manufacture of equipment for oil and gas industry, which operate in chemically aggressive environments. Permissible application temperature of parts made from this steel, up to 1050…1100°C.

Melting steel this grade should be either an induction/arc furnaces, or by the technology of electroslag remelting, which leads to reduced tolerances on the composition of alloying elements and a sharp restriction on the content of non-metallic impurities. The percentage of sulphur and phosphorus in steel should not exceed the value of 0.025…0,030%. Rolling steel, because of its high strength, is produced only in the hot state. Properties

Mechanical characteristics :

  • The limit of strength, MPa — not more than 1270;
  • Yield strength, MPa — not more than 1080;
  • Brinell hardness number, HB, no more than 363.
  • Relative tensile elongation, % of 12;

Treatment

  • Annealing — heating from 1010o C to 1 120o C and subsequent rapid cooling in air or in water. The best corrosion resistance corresponds to the final temperature of annealing 1070 °C;
  • Annealing for stress relieving — heating to a 200… 400o C with subsequent cooling in air;
  • Hot stamping/forging: the forging temperature range of 940 — 1200o C
  • Cold forging difficult.
