Description
The structural Steel alloyed 40HFA. For improvement of physical, chemical, strength and technology properties of steel alloy, entering into their structure different doping elements (chrome, manganese, nickel, etc.) . Steel may contain one or several doping elements which give them special properties. The alloyed structural steel divides into basic groups: The cemented alloy steels; The Improved alloy steels; High-strength alloy steels. Structural alloyed steel 40HFA 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 40HFA corresponds: Plastic metal working. Forgings of B03 of GOST 8479-70, TU 0306.018-80, ST TsKBA 010-2004 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 1051-73, GOST 4543-71, GOST 7417-75, GOST 8559-75, GOST 8560-78, GOST 14955-77, TU 3-1053-86, TU 14-1-1609-76, TU 14-1-2118-77, TU 14-1-950-86, TU 14-11-245-88, TU 14-1-5228-93, TU 14-136-367-2008 of the Pig. Preparations. B31 slabs OST 3-1686-90, TU 14-1-4944-90, TU 1-92-156-90 Thermal and thermochemical processing of TsKBA B04 CT metals of 026-2005 V the chemical composition steel 40HFA contains chemical elements in %: From 0,37 - 0,44 Si 0,17 - 0,37 Mn 0,5 - 0,8 Ni to 0,3 S to 0,025 P to 0,3 Fe ~ 96 Use of alloy steel 40HFA increase durability of products to 0,025 Cr 0,8 - 1,1 V 0,1 - 0,18 Cu, saves metal, increases productivity, simplifies design and therefore in progressive equipment gains crucial importance. Physical, technology and mechanical properties of steel 40HFA: Specific weight: 7810 kg/m3 Heat treatment: Tempering and issue Forging temperature, °C: beginnings 1250, end 860-800. Sections to 200 mm are cooled in a charging box, 201-300 mm - with the furnace. Hardness of material: HB 10-1 = 241 MPas Temperature of critical points: Ac1 = 760, Ac3(Acm) = 800, Ar3(Arcm) = 725, Ar1 = 680, Mn = 218 Workability cutting: after tempering and issue at HB ≤ 241, K υ TV. spl =0,75, Kυ B. St =0,65 Bondability of material: hardly welded. Welding methods: RDS - are necessary heating and the subsequent heat treatment. KTS - is necessary the subsequent heat treatment. Flokenochuvstvitelnost: it is sensitive. Tendency to temper brittleness: it is inclined. Alloy steel 40HFA 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 40HFA is applied to hard loaded metalwork. Use of steel in the industry: for production in the improved condition of castellated shafts, rods, setting screws, a traverse, shaft of the excavators and other parts working at a temperature up to +400 °C; after tempering and low issue - for production of worm shafts and other parts of the increased wear resistance; after tempering in oil and issues on air - for production of parts of pipeline armature. Note: High-quality structural Steel chrome-vanadium. Buy the Forging round 40HFA legko:1. You send zayavku2. We expose to you schet3. You pay convenient for you sposobom4.
