High-alloy heat steel 18H12VMBFR. High-alloy steel 18H12VMBFR — the steel containing more than 10% of doping elements. Quality and a type of supply of steel 18H12VMBFR corresponds: High-quality and structural shape of B22 of GOST 1133-71, GOST 2590-2006, state standard specification 2591-2006 Classification, nomenclature and general norms of B30 of GOST 5632-72 High-quality and structural shape of B32 of GOST 5949-75, TU 14-1-552-72, TU 14-11-245-88 of the Pig. Preparations. B31 slabs OST 3-1686-90 Heat high-alloy steel 18H12VMBFR can resist to mechanical loadings, and also resist oxidation and an okalinoobrazovaniye - and steel is capable to make all this at high temperatures: 400 - 1250 °C. In the chemical composition steel 18H12VMBFR contains chemical elements in %: From 0,15 - 0,22 Si to 0,5 Mn to 0,5 Ni to 0,06 S to 0,025 P to 0,03 Cr 11 - 13 Mo 0,4 - 0,6 W 0,4 - 0,7 V 0,15 - 0,18 Nb of 0,2 - 0,4 B to 0,003 Fe ~ 85 Heat resisting call material which can sustain influence of high temperatures, without losing at the same time the mechanical strength. Physical, technology and mechanical properties of steel 18H12VMBFR: Heat treatment: Normalization 1050oC, Cooling air, Issue 750oC, 3 h, Cooling air, Hardness of material: HB 10-1 = 229 MPas Temperature of critical points: Ac1 = 850, Ac3(Acm) = 930 Bondability of material: it is not applied to welded designs. The recommended maximum temperature of operation during very long time of +500 °C. Temperature of the beginning of an intensive okalinoobrazovaniye in air environment of +750 °C. Apply heat high-alloy steel 18H12VMBFR in production of boilers, heat treatment furnaces, heat exchangers, paroperegrevatelny devices, blades of steam turbines, pipelines of a high pressure. Also this group of staly is suitable for production of the equipment which will work in aggressive environments at high temperatures. Widely apply steel 18H12VMBFR in chemical, oil, power mechanical engineering and other industries to production of the designs working with the broad range of temperatures. Thanks to high mechanical properties at negative temperatures high-alloy steel and alloys apply in some cases and as cold-resistant. Use of steel 18H12VMBFR in the industry: for production of forgings, blades of steam turbines, pipes and mounting parts for long service life at temperatures up to +620 °C; for production by cold machining and hot working pressure of mounting parts of turbines and flanged couplings of the steam lines and armature working at a temperature of couple 500-580 °C. Note: Steel of a martensito-ferritic class. Buy the Circle 18H12VMBFR EI993 legko:1. You send zayavku2. We expose to you schet3. You pay convenient for you sposobom4.
