The High-Temperature Strength and Plastic Properties of Selected Low-Alloyed Cr-Mo Steels

Popis výsledku v původním jazyce

With using of the simulator HDS-20, the strength and plastic properties of two selected low-alloyed Cr-Mo steels, which were differing by carbon and manganese content, were experimentally investigated. By a special test consisting of loading of tested specimen by the small constant tensile force of 80 N in the whole course of his heating, the nil-strength temperature of the investigated steels was determined. The steel with the higher carbon content showed about of 42 oC lower nil-strength temperature. By uniaxial tensile tests to rupture which were performed in the range of deformation temperatures of 800 - 1410 oC at the constant tensile rate of 20 mm.s-1 and 1000 mm.s-1, the strength and plastic properties of the investigated steels were examined. The different carbon content did not significantly influence the strength properties of the investigated steels in the examined range of deformation temperatures. In the case of the hot ductility, similar results were obtained, but the steel with the higher carbon content showed about of 35 oC lower nil-ductility temperature. The difference between the nil-strength temperature and nil-ductility temperature was 39 oC and 32 oC in the case of the steel with the carbon content of 0.31 wt. % and 0.43 wt. %, respectively.
