Pipe 15X5M

The heat steel low-alloyed 15X5M. Low-alloy steel 15X5M – steel with the content of alloying constituents which sum is less than 2,5%. Low-alloy steel is metal at chemical composition of which in addition to iron, carbon and obligatory impurity there are special so-called alloying additions. Quality and a type of supply of steel 15X5M corresponds: Bar, including shaped: GOST 20072-74, GOST 2590-2006, GOST 2591-2006. The calibrated bar: GOST 8559-75, GOST 8560-78, GOST 7417-75. Polished bar and silver steel: GOST 7417-75. The leaf is thick: GOST 7350-77. Strip: GOST 103-2006, GOST 4405-75. Forgings and shod preparations: GOST 1133-71. Pipes: GOST 550-75, GOST 8732-78, GOST 8734-75, GOST 9567-75. In the chemical composition steel 15X5M contains chemical elements in %: vanadium (V), no more than 0.05; tungsten (W), no more than 0.3; silicon (Si), no more than 0.5; manganese (Mn), no more than 0.5; copper (Cu), no more than 0.20; molybdenum (Mo) 0.45-0.60; nickel (Ni), no more than 0.6; sulfur (S), no more than 0.025; titanium (Ti), no more than 0.03; carbon (C), no more than 0.15; f osfor (P), no more than 0.030; chrome (Cr) 4.5-6.0. Heat resisting call material which can sustain influence of high temperatures, without losing at the same time the mechanical strength. Heat resisting low-alloy steel 15X5M at high temperatures and sustained loads technically differs in high strength. Steel 15X5M has the sufficient high size of a creep stress and long-term strength. Physical, technology and mechanical properties of steel 15X5M: Specific weight: 7750 kg/m3 Heat treatment: Annealing 840 - 860oC to bake Cooling. Hardness of material: HB 10-1 = 170 MPas Forging temperature, °C: beginnings 1200, end 800. Sections to 800 mm are exposed to annealing with recrystallization and to one overcooling. Temperature of critical points: Ac1 = 815, Ac3(Acm) = 848, Ar3(Arcm) = 775, Ar1 = 718 Workability cutting: in a goryachetkany state at HB 170 and σв =390 MPas, To υ TV. spl =2,7 and Kυ B. St =2,0 Bondability of material: hardly welded. Welding method: RDS. The heating and the subsequent heat treatment are necessary. Flokenochuvstvitelnost: it is sensitive. Tendency to temper brittleness: it is not inclined. Stal15kh5m perfectly will be suitable for production of the designs working in the conditions of high temperatures – 350-400 C and considerable tension. From heat resisting low-alloy steel 15X5M make boilers, the petroequipment, etc. parts which work in the environments destroying metal chemically and mechanically. Use of steel 15X5M in the industry: pipes, latches, fixture and other parts from which oxidation resistance is required at a temperature up to 600-650 °C.; steel of a martensitic class.
