analysis of changes in microstructure in steel C45 and Ni3.5CrMoV has been presented in work . 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.
Forming of C45 Steel at Critical Temperature - ScienceDirect
Experimental The experimental programme was performed using structural carbon steel C45 with the chemical composition listed in Table 1. The initial microstructure consisted of ferrite and lamellar pearlite with pronounced banding along the axis of the bar stock.
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.

greater thicknesses, alloyed steel grades are used. The microstructure and hardness values after heat treatment are shown in Fig. 2, TTT diagram (Time-Temperature- Transformation) for steel C45. The diagram shows the transformation behavior at an austenitizing temperature of 870°C and a
C45 steel is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition.Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned, ground and polished.
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
