WebDefinice tvrdosti. Tvrdost je definována jako odpor, který klade materiál proti vnikání cizího tělesa. Hodnoty tvrdosti se většinou uvádějí bezrozměrně s udáním způsobu měření nebo stupnice. Tvrdost [H] je mechanická vlastnost, která je velmi důležitá v technické praxi především pro kovové materiály. Tvrdost lze ... WebEN8 is suitable for the manufacture of parts such as general-purpose axles and shafts, gears, bolts and studs. It can be further surface-hardened typically to 50-55 HRC by induction processes, producing components with enhanced wear resistance. For such applications the use of EN8D (080A42) is advisable. It is also available in a free …

WebGeneral Information. 100Cr6 is a through hardening bearing steels intended for rolling contact and other high fatigue applications. In the hardened condition the high hardness, high strength and high cleanliness provides the steel with the right properties to withstand high cycle, high stress fatigue. 100Cr6 is mainly used for small and medium ... WebA useful conversion used extensively in applications involving H 2 S is that 22 HRC (Rockwell C) is equivalent to 248 HV (Vickers), which is often rounded to 250 HV. An earlier standard, BS 860:1967 [3], which has been superseded by BS EN ISO 18265:2003 gives the following equation for hardness conversion between Brinell and Vickers scales. HB ...
