Description
40X13 steel is used: for the manufacture of cutting, measuring tools, springs, carburetor needle, household items, valve plates, compressors and other parts operating at temperatures up to 400−450 °C; parts operating in corrosive environments; the various parts of the aircraft industry (parts with high hardness, wear working at high mechanical loading and under conditions of relaxation (stainless springs, bolts, finger, fittings, axles and bearings of the instrument).
Note
Steel chromium corrosion-resistant martensitic class.
Steel is used after quenching and low tempering with ground and polished surface has a high hardness.
Because of the tendency of steel to spontaneous cracking immediately after quenching the part is subjected to release.

| Features of heat treatment | Steel products can be subjected to hardening, leave, annealing. The quenching and tempering of the products is done to achieve: a) maximum corrosion resistance; b) the specified level of mechanical properties. Hardening of steel products is carried out in oil with 1000-1050 °C. the holding Time at the heating for hardening to products with a wall thickness or diameter up to 10 mm - 20 min., above 10mm-20 min + 1 min per 1 mm maximum thickness. Steel sensitive to cracking, so heating of thick-walled and complex configuration of products for hardening start with 500-650 °C and are slowly to 800 °C, after equalizing the temperature of the heating rate should be increased. Immediately after quenching (in order to avoid spontaneous cracking) products of martensitic steels must be subjected to the release. The maximum strength properties of the products acquired after the holidays according to the mode: heating up to 250-300 °C, exposure 1-3 h, air cooling. Maximum corrosion resistance and formability products acquired after the holidays according to the mode: heating up to 700-750 °With, exposure time - 20 min + 1 min per 1 mm maximum metal thickness, but not less than 40 min, cooling in oil. Softening heat treatment is annealing at 750-850 °C with cooling with the furnace to 500 °C. is Not allowed to make a vacation at 450-550 °C, Since this leads to a decrease in toughness. Workpiece to improve the mechanical workability is subjected to intermediate annealing at 600-760 °C for 2-4 h. |
