Description
Relaksatsionnostoyky heat steel 25H2M1F. Relaksatsionnostoyky heat steel 25H2M1F is applied to creation of various parts and products: • Rotors and shaft; • Bolts and nuts; • Flanges and forgings of general purpose; • Disks of steam turbines; • Pipes for the chemical equipment; • Billets; • Bars and pins. Quality and a type of supply of steel 25H2M1F corresponds: Bar, including shaped: GOST 20072-74, GOST 2590-71, GOST 2591-71. The calibrated bar of GOST 7417-75, GOST 8559-75, GOST 8560-78. Strip of GOST 103-76, GOST 4405-75. Forgings and shod preparations of GOST 1133-71, GOST 8479-70. Relaxation steel 25H2M1F has the lowest creep and high elasticity of a crystal lattice. These properties allow to apply with success heat relaxation resisting steel 25H2M1F at production of springs, pins, bolts, the fixing elastic brackets and other parts expected operation at temperature conditions to 500 C. In the chemical composition steel 25H2M1F contains chemical elements in %: %: vanadium (V) 0.30-0.50; silicon (Si) 0.17-0.37; copper (Cu), no more than 0.20; molybdenum (Mo) 0.90-1.10; manganese (Mn) 0.40-0.70; nickel (Ni), no more than 0.30; phosphorus (P), no more than 0.030; chrome (Cr) 2.10-2.60; sulfur (S), no more than 0.025. Heat resisting call material which can sustain influence of high temperatures, without losing at the same time the mechanical strength. Physical, technology and mechanical properties of steel 25H2M1F: Specific weight: 7800 kg/m3 Heat treatment: Normalization of 1030 - 1060oC, Issue 680 - 720oC, air. Forging temperature, °C: beginnings 1200, end 800. Hardness of material: HB 10-1 = 235 - 277 MPas Temperature of critical points: Ac1 = 780, Ac3(Acm) = 870, Ar3(Arcm) = 790, Ar1 = 700 Workability cutting: in the normalized and released state at HB ≤ 300 and σв =1030 MPas, To υ TV. spl =0,6 and Kυ B. St =0,25 Bondability of material: Use of steel 25H2M1F in the industry is not applied to welded designs: with a working temperature of 520-540 to °skupit bolts, flat springs, nuts and other mounting parts the Forging round 25H2M1F EI723 legko:1.
