As a farther result, the high temperature creep properties of the 12Cr1MoV steel are appraised by numerical simulation. The results are in good agreement with the results from the standard test method. The results indicate that the small punch test technique is an effective method for the evaluation of the high-temperature creep properties of
CHAPTER 7 12CrlMo STEEL - Harry BhadeshiaAs a result of the very high chromium concentration of 12Cr1MoV steel, the reaction kinetics are rapid compared to those in low alloy steels. It is found that the equilibrium alloy carbide precipitates during the commercial stress-relief heat treatment and does not change in composition during further tempering.
CN103357993B - A kind of welding procedure of 12Cr1MoV 12Cr1MoV belongs to pearlite heatproof steel, and institutional framework is granular pearlite+a small amount of ferrite, and it not only has good non-oxidizability and heat resistance, has the
Jun 01, 2018 · 12Cr1MoV steel is a commonly utilized high temperature material for components such as heat pipes in fired power plants. Inhomogeneous microstructures and porosity are the primary problems during its manufacture. The chemical composition of the
Henan BEBON international ,ltd12Cr1MoV steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of Steel for large diameter pipes,12Cr1MoV steel with the demands in mechanical properties of the pipes followed the API specification for grade12Cr1MoV (YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers
In-situ investigation of tensile deformation and fracture Jul 17, 2017 · 12Cr1MoV steel has been widely used as steam pipelines, superheaters and reheaters which are long-term operated at temperatures below 580 °C in thermal power plants (TPP) due to its good creep resistance, high oxidation and hot-corrosion resistance,,,.
Jan 01, 2015 · Abstract. 12Cr1MoV is one of the low alloy steels which is widely applied in heat pipes of biomass fired boilers. But with the combined effects of molten alkali salts corrosion caused from combustion of biomass and creep deformation which is resulted by the high temperature stress as well as steam pressure, they bring negative influence on the mechanical properties.
Microstructures and Mechanical Properties of 12Cr1MoVG Sep 19, 2017 · Small-caliber, thick-wall 12Cr1MoVG seamless steel tube welded joints were fabricated in this study by gas tungsten arc welding and shielded metal arc welding techniques, then the microstructures, mechanical properties, and residual stress distributions of the joints with or without post-weld heat treatment (PWHT) were compared. The welded joints are mainly composed of bcc ferrite
Property changes of 12Cr1MoV with 10CrMo910 main steam Apr 01, 2003 · It is obvious that both 12Cr1MoV and 10CrMo910 pertain to CrMo low-alloy steels and the main alloying elements are Cr and Mo. Carbon in both steels is 0.080.15%, which is relatively low and advantageous to stability. The amount of Cr and Mo in 12Cr1MoV is lower than in 10CrMo910, but 12Cr1MoV contains the element V which 10CrMo910 lacks.
