Forging round 25H2GNTA

The structural Steel alloyed 25H2GNTA. 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 25H2GNTA 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 25H2GNTA corresponds: Classification, nomenclature and general norms of B20 OST 1 90005-91 Pigs. Preparations. Slabs of B31 of TU 14-1-1030-74, TU 1-92-156-90 the High-quality and structural shape of B32 of TU 14-1-1885-85, TU 14-1-3238-81 of the Pipe steel and connectors of TU B62 to them 14-3-289-74 V the chemical composition steel 25H2GNTA contains chemical elements in %: From 0.22 - 0.29 Si 0.2 - 0.5 Mn 0.8 - 1.1 Ni of 0.9 - 1.3 S till 0:03 P till 0:03 Cr 1.3 - 1.7 Ti 0.06 - 0.12 Cu to 0.3 Use of alloy steel 25H2GNTA 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 25H2GNTA: Heat treatment: Tempering 860oC, oil, Issue 200 - 230oC, 2 - 3 h, Can be applied at a temperature up to -80 °C (wall thickness no more than 100 mm). Alloy steel 25H2GNTA 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 25H2GNTA is applied to hard loaded metalwork. Use of steel in the industry: for production of beams, bolts, axes, the vessels working under excessive internal pressure; wreaths of driven wheels of traction tooth gearings of electric trains, a gear wheel and other improved parts; round billets and pipes. Note: Chrome high-quality high-strength alloy steel. Buy the Forging round 25H2GNTA legko:1. You send zayavku2. We expose to you schet3. You pay convenient for you sposobom4.
