Description

Steel 30CH13 used: for the manufacture of cutting, measuring tools, springs, carburetor needle rods reciprocating compressors, parts of internal devices devices and various other parts that work wear in a slightly aggressive media up to +450 °C; for the production of various critical parts of the aircraft industry, springs, designed for operation at temperatures up to 300−350 °C and other components operating at high voltages; spring persistent flat internal eccentric rings used for fixation of parts in buildings up to +300 °C; solid-rolled rings for different purposes.

Note

Steel chromium corrosion-resistant martensitic class.
Steel is used after quenching and low tempering with ground and polished surface has a high hardness.

Weldability Does not apply to welded structures.
Propensity to temper brittleness Malosolone.
Forging temperature Start - 1250 °C, the end - 850 °C. the cross Sections up to 400 mm are subjected to low-temperature annealing, one hypothermia.
Flock-sensitive sensitivity not sensitive.
Workability by cutting In the hardened and tempered condition with a NV 241 and blower SB=730 MPa Kn TV.SPL.=0,7 Kn b.St.=0,45. To improve the machinability and the hardness HB ≤ 205 of the workpiece is subjected to annealing at 740-780 °C for 2-6 h with air cooling.
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. the Elastic elements, made of steel 30X13, after quenching is subjected to release at 400 °C exposure time 1-2 h, air cooling. Not allowed 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 To obtain characteristic values of mechanical properties and hardness set ST CKBA 010 and to achieve maximum corrosion resistance, parts (workpiece) valves shall be subjected to hardening and tempering. The heating of the parts (workpieces) in the temperature range from 500 °C to 800 °C must be carried out at a speed of not more than 200 °C per hour. In the temperature range 750 - 800 °C it is necessary to give exposure to the full heating of the charge. Further heating to the quenching temperature produced by the furnace. For parts with thickness (diameter) up to 120 mm the rate of heating is not limited and aging at a temperature of from 750 °C to 800 °C is not possible. The time between quenching and the beginning of vacation - less than 3 hours. Parts included in friction and sealing shutter valves, can be subjected to surface hardening with heating by high frequency currents (HFC) with the aim of improving hardness while maintaining high mechanical properties in the core part. Surface hardening with heating HDTV applies to parts of thickness (diameter) of not less than 15 mm and is made only after a preliminary heat treatment improves the hardness to 36.5 HRC.
