Circle of 90 mm 20HGSA

The structural Steel alloyed 20HGSA. Structural alloyed steel 20HGSA 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 20HGSA corresponds: High-quality and structural shape of B22 of GOST 1133-71, GOST 8319.0-75, GOST 2590-2006, GOST 2591-2006, GOST 2879-2006 Sheets and strips of B23 of GOST 103-2006 High-quality and structural shape of B32 of GOST 4543-71, GOST 7417-75, GOST 8559-75, GOST 8560-78, GOST 10702-78, GOST 14955-77, OST 1 92049-76, TU 14-1-2118-77, TU 14-11-245-88, TU 14-1-1271-75, TU 14-1-5228-93, TU 14-136-367-2008 Pigs.

Use of alloy steel 20HGSA 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 20HGSA: Specific weight: 7760 kg/m3 Heat treatment: Tempering 880oC, oil, Issue 500oC, water Forging temperature, °C: beginnings 1200, end 800 Hardness of material: HB 10-1 = 207 MPas Temperature of critical points: Ac1 = 755, Ac3(Acm) = 840, Ar1 = 690 Bondability of material: without restrictions. RDS, KTS, ARDS, ADS under gumboil and gaseous protection, EShS - is required the subsequent heat treatment. Workability cutting: at HB 140-207, K υ TV. spl =0,7 and Kυ B. St of =0,60 Flokenochuvstvitelnost: it is not sensitive. Tendency to temper brittleness: it is inclined. Alloy steel 20HGSA 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 20HGSA is applied to hard loaded metalwork. Use of steel 20HGSA in the industry: the motion screws, axes, shaft, worms and other parts working in the conditions of wear and at sign-variable loadings at temperatures up to 200 to °s.kupit the Circle of 90 mm 20HGSA legko:1.
