Forging round 51HFA

Constructional spring spring steel 51HFA. Spring spring steel 51HFA is made according to GOST 14959-79. State standard specification 14959-79 — the standard extends to a hot and shod bar diameter or up to 250 mm thick, and also the rolling calibrated and with special finishing of a surface, intended for production of the springs, springs and other machine components and mechanisms applied in the tempered and released state. Range of spring spring steel 51HFA: The circle the hot-rolled GOST 2590-88 Square the hot-rolled GOST 2591-88 Circle and a square shod GOST 1133-71 Hexagon the hot-rolled hot-rolled GOST 2879-88 Strip of GOST - 103-76 Strip shod the GOST 14955-77 Quality and a type of supply of steel 51HFA corresponds to the GOST 4405-75 Circle the Calibrated GOST 7417-75 Square the Calibrated GOST 8559-75 Hexagon the Calibrated GOST 8560-78 Circle with special finishing of a surface: The high-quality and structural shape of the GOST 14959-79, TU 14-1-1607-76, TU 14-1-2118-77, TU 14-11-245-88, TU 14-136-367-2008 Wire Steel Average and High-carbon B72 of GOST 1071-81 of B32, the state standard specification 26366-84, TU 14-4-238-72 Wire the Steel Alloyed B73 of the GOST 14963-78, TU 14-4-1130-81 Classification, the nomenclature and the general norms of B20 OST 1 90005-91 Tapes B34 TU 14-173-180-89, TU 14-4-843-77 V the chemical composition steel 51HFA contains chemical elements in %: With 0,47 - 0,55; Si 0,15 - 0,3; Mn 0,3 - 0,6; S to 0,025; P to 0,025; Cr 0,75 – 1; V 0,15 - 0,25; Fe ~ 97. Spring spring steel 51HFA should provide the high resistance to small plastic strains and relaxation firmness. The springs made of such steel differ in the accuracy and reliability of work. If from a spring of steel 51HFA production of a wire and tape is meant, then it is in addition strengthened cold plastic strain and martempering with the subsequent issue. Steel 51HFA is suitable for production of springs, springs, torsions, flexible membranes, sylphons, etc. Steel 51HFA as well in automobile production for production of automobile springs and springs is used. Use of steel 51HFA in the industry: for the production of rolled wire, a tape used for production of heavy-duty strength members to which requirements of high fatigue resistance are imposed; thermally processed wire with a diameter of 1,2-5,5 mm intended for production of cylindrical compression springs. Note: Steel the spring and spring alloyed high-quality. Buy the Forging round 51HFA legko:1. You send zayavku2. We expose to you schet3. You pay convenient for you sposobom4.
