DILATOMETRIC AND HARDNESS ANALYSIS OF C45

analysis of changes in microstructure in steel C45 and Ni3.5CrMoV has been presented in work [9]. In weld-ing processes and laser treatment occurs dynamic tem-perature change, while time of peak tempearture during tempering lasts from several to hundreds of seconds. Short austenisation time, as well as of tempering lead to heterogeneous structure.

Induction heat treatment of a ISO C45 steel bar

An experimental and numerical study was carried out on the induction hardening process of type C45 steel. The test pieces have been used both in the annealed and normalised states. The hardened depth and the microstructure of the samples were investigated through conventional microstructure and micro-hardness analyses.

C45 Round Bar AISI 1045 DIN 1.1191 JIS S45C - Otai

C45 is a medium strength steel with good machinability and excellent tensile properties. C45 round steel is generally supplied in the black hot rolled or occasionally in the normalised condition, with a typical tensile strength range 570 – 700 Mpa and Brinell hardness range 170 – 210 in either condition.

Important Machining Factors of Carbon SteelsProduction

Mar 22, 2006 · It is the increase in this pearlite phase, driven by the carbon content, that explains the increase in the steel’s mechanical properties, especially the hardness. Above 0.60 carbon in plain carbon steels, a thermal treatment called an anneal is used to modify the microstructure and reduce the steel
