Stainless steel 50Х14МФ are manufactured in accordance with GOST R50 328 1−92 and international standard MSO 7153/1−88. The alloy composition contains: chrome 14−15%, silicon and manganese of 0.6%, carbon — 0,48−0,55%, molybdenum — 0,45−0,8%, vanadium 0.1% to 0.15%, sulfur, phosphorus in thousandths of a percent. The base is iron.
This alloy belongs to the class of martensitic steel is smelted in open electric arc and induction furnaces or vacuum induction furnaces with subsequent vacuum arc remelting. Rolled steel after quenching hardened as the result of the martensitic transformation, the optimum hardness is achieved by quenching temperature of 1050 °C. the Structure of granular perlite gives the annealing, after quenching the hardness is 197−207 HB-1. In the temperature range 900 — 1100 °C, this steel products of this brand is easy to hot deformation. The blanks produced by rolling a varietal — drawing. During fast cooling, the formation of cracks.
The corrosion rate
— in moist ammonia and hydrogen sulfide atmosphere up to 0.005 mm/year;
— in a solution containing hydrogen sulphide (saturation 2.5 g/l), less 0,0135 mm/year;
— in an aqueous solution of ammonia (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) up to 0,003 mm/year;

Steel for knives 50Х14МФ (эи128) is used in medical industry (in the manufacture of cutting tools, for example, a removable surgical blade, all-metal scalpels); and knives in the food industry. Products made from this steel meet the highest requirements of corrosion resistance and can withstand repeated thermal processing is necessary for medical instruments. You can process them in the washing machines, they do not lose their properties in chlorinated water.
