Description
Tool steel carbonaceous U7A. Tool steel carbonaceous U7A corresponds to GOST 1435-99. Steel with carbon content higher than 0,7% is called tool carbonaceous. After final heat treatment tool U7A carbon steel is characterized by the high hardness and durability. Quality and a type of supply of U7A steel corresponds: Bar, including shaped: GOST 1435-74, GOST 2590-71, GOST 2591-71, GOST 2879-69. The calibrated bar of GOST 1435-74, GOST 7417-75, GOST 8559-75, GOST 8560-78. Polished bar and state standard specification 1435-74, GOST 14955-77 silver steel. Tape state standard specification 2283-79, GOST 10234-77, GOST 21997-76. Strip of GOST 103-76, GOST 4405-75. Forgings and shod preparations of GOST 1435-74, GOST 4405-75, GOST 1133-71. In the chemical composition U7A steel contains chemical elements in %: Silicon (Si) 0.17-0.33; Copper (Cu), no more than 0.20; Manganese (Mn) 0.17-0.28; Nickel (Ni), no more than 0.20; Phosphorus (P), no more than 0.030; Chrome (Cr), no more than 0.20; Sulfur (S), no more than 0.028. Advantages of tool U7A carbon steel: differs in the small cost and rather high hardness. Shortcomings of tool U7A carbon steel: small wear resistance and low heat resistance. Physical, technology and mechanical properties of U7A steel: Specific weight: 7830 kg/m3 Hardness of material: HB 10-1 = 187 MPas Temperature of critical points: Ac1 = 730, Ac3(Acm) = 770, Ar1 = 700, Mn = 280 Forging temperature, °C: beginnings 1180, end 800. Sections to 100 mm are cooled on air, 101-300 mm in a hole. Workability cutting: in an annealed state at HB 187, σв =620 MPas, To υ TV. spl =1,2 and Kυ B. St =1,1 Bondability of material: it is not applied to welded designs. Flokenochuvstvitelnost: it is not sensitive. Tendency to temper brittleness: it is not inclined. Tool U7A carbon steel is used for production of the cutting, measuring, stamping tool (drills, files, taps, development, etc.) the small sizes, working in rather easy conditions (small speeds, heating temperature there is not higher than 2000 ºС). Use of U7A steel in the industry: the tool which works in the conditions which are not causing a warming up of a working edge: chisels, chisels, small beards, hammers, edges of scissors for metal cutting, axes, splitting axes, chisels, flat-nose pliers combined of a sledge hammer.
