Description
Tool die steel 5HNM. Tool die steel 5HNM is made according to GOST 5950-2000. Quality and a type of supply of steel 5HNM corresponds: Classification, nomenclature and general norms of GOST 5950-2000 High-quality and structural shape of GOST 2590-2006, GOST 2591-2006, GOST 7417-75, GOST 8559-75, GOST 8560-78, GOST 14955-77, TU 14-11-245-88, OST 1 92049-76, TU 14-1-1226-75, Sheets and strips of GOST 4405-75, TU 14-131-971-2001 of the Forging and shod preparations of GOST of 1133-71 Pig. Preparations. Slabs OST 24.952.01-89, TU 108.06.109-87 Plastic metal working. TU 108.11.917-87 forgings Welding and metal cutting. The soldering, a klepka of GOST 10543-98 Technology and mechanical properties of tool steel 5HNM are defined by availability of the chemical elements entering this steel. In the chemical composition steel 5HNM contains chemical elements in %: carbon (C) 0,5 - 0,6; silicon (Si) 0,1 - 0,4; copper (Cu), no more than 0,3; manganese (Mn) 0,5 - 0,8; molybdenum (Mo) 0,15 - 0,3; nickel (Ni) 1,4 - 1,8; phosphorus (P), no more than 0,03; chrome (Cr) 0,5 - 0,8; sulfur (S), no more than 0,03. Advantages of tool steel 5HNM are wear resistance, hardness penetration, heat resistance and high hardness. The major requirement imposed to die steel 5HNM — a hardness combination to high viscosity. Die steel 5HNM should possess also special technology characteristics which treat: a good workability, i.e. ability it is good to accept processing by cutting and pressure treatment in a cold and hot state; good hardness penetration, i.e. an opportunity to receive the high and homogeneous hardness, uniform fine-crystalline structure deeply; small sensitivity to an overheat, i.e. a possibility of tempering with heating in rather wide interval of temperatures; small deformation at heat treatment; small sensitivity to decarbonization at the heating reducing the hardness of a surface (worker) metal layer; the good sandability defining high quality of a polished and polished surface. Physical, technology and mechanical properties of steel 5HNM: Heat treatment: Tempering 850oC, oil, Issue 460 - 520oC. Forging temperature: ºС: beginnings 1240, end 750. Sections to 100 mm are cooled on air, 101-350 mm - in a hole. Hardness of material: HB 10-1 = 241 MPas Temperature of critical points: Ac1 = 730, Ac3(Acm) = 780, Ar3(Arcm) = 640, Ar1 = 610, Mn = 230 Bondability of material: it is not applied to welded designs. Flokenochuvstvitelnost: it is sensitive. Tendency to temper brittleness: it is not inclined. Workability cutting: in an annealed state at HB 286 and σв =900 MPas, To υ TV. spl =0,6 and Kυ B. St =0,3 Of tool die steel 5HNM make the stamps, rollers, rollers, punches and other tools necessary for plastic metal working. Use of steel 5HNM in the industry: molotovy stamps of steam-air and air hammers weighing falling parts over 3 t, press stamps and stamps of machine high-speed stamping at hot deformation of light color alloys, blocks of matrixes for inserts of horizontal forging machines.
