Description
The structural Steel alloyed 20X2H4A. Structural alloyed steel 20X2H4A 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 20X2H4A corresponds: Bar, including shaped: GOST 4543-71, GOST 2590-2006, GOST 2591-2006, GOST 2879-2006. The calibrated bar: GOST 7417-75, GOST 8559-75, GOST 8560-78, GOST 1051-73. Polished bar and silver steel: GOST 14955-77. Strip: GOST 103-2006. Forgings and forgings: GOST 1133-71. Pipes: OST of 14-21-77 V the chemical composition steel 20X2H4A contains chemical elements in %: silicon (Si) 0.17-0.37; copper (Cu), no more than 0.30; manganese (Mn) 0.30-0.60; nickel (Ni) 3.25-3.65; phosphorus (P), no more than 0.025; chrome (Cr) 1.25-1.65; sulfur (S), no more than 0.025. Use of alloy steel 20X2H4A 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 20X2H4A: Specific weight: 7850 kg/m3 Heat treatment: Tempering and issue Forging temperature, °C: beginnings 1200, end 800. Sections to 100 mm okhazhdatsya on air, 101-350 mm in a hole. Hardness of material: HB 10-1 = 269 MPas Temperature of critical points: Ac1 = 710, Ac3(Acm) = 800, Ar1 = 640 Workability cutting: after normalization and issue at HB 259 and σв =880 MPas, To υ TV. spl =0,72 and Kυ B. St =0,63 Bondability of material: hardly welded. Welding methods: RDS, ADS under gumboil, EShS. The heating and the subsequent heat treatment are necessary. Flokenochuvstvitelnost: Tendency to temper brittleness is sensitive: the malosklonn Alloy steel 20X2H4A 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 20X2H4A is applied to hard loaded metalwork. Use of steel 20X2H4A in the industry: gear wheels, a pinion shaft, fingers and other high-loaded members cemented especially strength to which requirements of high strength, plasticity and viscosity of a core and high surface hardness working under the influence of shock loads or at negative temperatures are imposed.
