Forging round 40X2H2MA

The structural Steel alloyed 40X2H2MA. Structural alloyed steel 40X2H2MA 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. The range of steel 40X2H2MA corresponds: hot-rolled square – GOST 2591-88, hot-rolled round – GOST 2590-88, hot-rolled hexagon – GOST 2879-88, hot-rolled strip – GOST 103-76, shod round and square – GOST 1133-71, calibrated round – GOST 7417-75, calibrated square – GOST 8559-75, calibrated hexagon – GOST 8560-78, silver steel – the GOST 14955-77 Quality and a type of supply of steel 40X2H2MA corresponds: Plastic metal working.

Preparations. B31 slabs: OST 3-1686-90, THAT 14-1-4944-90 V the chemical composition steel 40X2H2MA contains chemical elements in %: silicon (Si) 0.17-0.37; manganese (Mn) 0.30-0.60; copper (Cu), no more than 0.30; molybdenum (Mo) 0.20-0.30; nickel (Ni) 1.35-1.75; sulfur (S), no more than 0.025; carbon (C) 0.35-0.42; phosphorus (P), no more than 0.025; chrome (Cr) 1.25-1.65. Use of alloy steel 40X2H2MA 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 40X2H2MA: Heat treatment: Tempering and issue Forging temperature, °C: beginnings 1200, end 800. Sections to 10 mm are cooled on air, 101-350 mm in a hole. Hardness of material: HB 10-1 = 255 MPas Temperature of critical points: Ac1 = 740, Ac3(Acm) = 805 Bondability of material: hardly welded. Welding method: RDS. Neobodima heating and subsequent heat treatment. Flokenochuvstvitelnost: it is sensitive. Tendency to temper brittleness: it is not inclined. Alloy steel 40X2H2MA 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 40X2H2MA is applied to hard loaded metalwork. Use of steel 40X2H2MA in the industry: large products: shaft, disks, geared gear wheels, and also mounting parts.
