Pipe 12H1MF

The heat steel low-alloyed 12H1MF. Low-alloy steel 12H1MF – 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 12H1MF 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. The leaf is thick: GOST 5520-79. Strip: GOST 103-2006, GOST 4405-75. Forgings and shod preparations: GOST 1133-71. In the chemical composition stal12kh1mf contains chemical elements in %: carbon (C) 0,08-0,15; vanadium (V) 0.15-0.30; silicon (Si) 0.17-0.37; copper (Cu), no more than 0.20; molybdenum (Mo) 0.25-0.35; manganese (Mn) 0.40-0.70; nickel (Ni), no more than 0.30; phosphorus (P), no more than 0.025; chrome (Cr) 0.90-1.20; sulfur (S), no more than 0.025. 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 12H1MF at high temperatures and sustained loads technically differs in high strength. Steel 12H1MF has the sufficient high size of a creep stress and long-term strength. Physical, technology and mechanical properties of steel 12H1MF: specific weight: 7800 kg/m3; heat treatment: Normalization 960 - 980oC, Issue 740 - 760oC.; forging temperature, °C: beginnings 1240, end 780. Sections to 50 mm 51-100 mm in boxes are cooled in stacks, 500-600 mm are exposed to low-temperature annealing; hardness of material: HB 10-1 = 123 - 179 MPas; temperature of critical points: Ac1 = 760, Ac3(Acm) = 890, Ar3(Arcm) = 825, Ar1 = 730, Mn = 430; workability cutting: in the normalized and released state at HB ≥ 138 and σв =460 MPas, To υ TV. spl =1,5 and Kυ B. St =1,35; bondability of material: restrictedly welded. Welding methods: RDS, ADS of poses gaseous protection. Steel 12H1MF 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 12H1MF make boilers, the petroequipment, etc. parts which work in the environments destroying metal chemically and mechanically. Use of steel 12H1MF in the industry: for production of the parts working at a temperature of 540-580 to °s.kupit the Pipe 12H1MF legko:1. You send zayavku2. We expose to you schet3.
