Circle 18HGT

The structural Steel alloyed 18HGT. Structural alloyed steel 18HGT is produced according to GOST 4543-71. Steel in which along with normal impurity there are alloyed elements which are sharply improving it properties is called alloyed: chrome, tungsten, nickel, vanadium, molybdenum, etc., and also silicon and manganese in a large number. Impurity are entered in melting process. Quality and a type of supply of steel 18HGT corresponds: Bar, including shaped GOST 4543-71, GOST 2590-71, GOST 2591-71, GOST 2879-69. The calibrated bar of GOST 7417-75, GOST 8559-75, GOST 8560-78, GOST 1051-73. Polished bar and state standard specification 4543-71, GOST 14955-77 silver steel. GOST 103-76 steel strip. Forgings and shod preparations of GOST 1133-71. In the chemical composition steel 18HGT contains chemical elements in %: Silicon (Si) 0.17-0.37; Manganese (Mn) 0.80-1.10; Copper (Cu), no more than 0.30; Nickel (Ni), no more than 0.30; Sulfur (S), no more than 0.035; Titanium (Ti) 0.03-0.09; Carbon (C) 0.17-0.23; Phosphorus (P), no more than 0.035; Chrome (Cr) 1.00-1.30. Use of alloy steel 18HGT increases durability of products, saves metal, increases productivity, simplifies design and therefore in progressive equipment gains crucial importance. Physical, technology and mechanical properties of steel 18HGT: Specific weight: 7800 kg/m3 Heat treatment: Tempering 850oC, oil, Issue 200oC, air Hardness of material: HB 10-1 = 217 MPas Forging temperature, °C: beginnings 1200, end 800. Sections to 250 mm are cooled on air, 521-350 mm - in a hole Temperature of critical points: Ac1 = 740, Ac3(Acm) = 825, Ar3(Arcm) = 730, Ar1 = 650, Mn = 360 Workability cutting: after normalization at HB 156-159 and σв =530 MPas, To υ TV. spl =1,1 and Kυ B. St =1,0 Bondability of material: without restrictions. (except chemical thermally finished parts). Welding methods: RDS, KTS. Flokenochuvstvitelnost: it is not sensitive. Tendency to temper brittleness: malosklonna. Alloy steel 18HGT is widely applied in tractor and agricultural mechanical engineering, in automotive industry, basic and transport engineering industry to a lesser extent in machine-tool construction, tool and other types of the industry. Steel 18HGT is applied to hard loaded metalwork. Use of steel 18HGT in the industry: the improved or cemented parts of responsible assignment from which the increased durability and viscosity of a core, and also the high surface hardness working under the influence of shock loads is required.
