Abstract:
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 °C lower nil-strength temperature. [..]

Abstract:
Thanks to their specific features (such as corrosion resistance, resistance to high temperatures, good mechanical properties, unique physicochemical and aesthetic properties) stainless steels are practically applied in many areas, including construction and architecture, energy production, household appliances, automotive, food, chemical and pharmaceutical industries. Stainless steel products are usually manufactured from three basic steel grades: 301, 304, 314 or 316L, which are high in nickel content. [..]
