AISI 1045 1.1191 C45 S45C - Waldun Steel

AISI 1045 is defined as medium carbon steel which has 0.43%-0.5% Carbon.It offers good weldability, good machinability, high strength and impact properties,but low in hardenability because of lack of suitable alloying elements,but it can obtain surface hardnesses 54-60HRC after flame or induction hardening. AISI 1045 is generally supplied in the black hot forged or normalized condition,and has Carburizing 101:Everything You Need to KnowCase hardening is a process which involves adding a hard, protective shell to the outside of an otherwise soft steel. This process allows for intricately shaped metals to possess a strength and toughness that they otherwise wouldn't be able to possess.


hardened C45 steel subjected to tempering. The analysis of the infl uence of heating rate at the kinetic determined from dilatometric curves has been made. There have also been estimated quantities of transformation expansions and thermal expansion coeffi cients of hardening and tempering structures (austenite, ferrite, pearlite, martensite Flame Hardening - Process, Diagram, Advantages, ApplicationIt is a surface-hardening process in which a thin surface section of a component of hardenable steel is heated rapidly by direct application of high tempe­rature flame to a temperature above its upper critical temperature (i.e., it is austenitized), and then the component is quickly quenched in water or oil, transforming austenite to mar­tensite, while the core remains in an original soft state, normally Hardening EN8 / EN9 parts. Q&A's, Problems & SolutionsFeb 18, 2021 · My situation:We have taken C45 grade 4.00 mm thick 70 mm wide material for hardening. Carbon % 0.425 and Mn% 0.66. In last lot used with same heat material hardness achieved 46 to 48 HRC, this month lot achieving hardness 37 to 38 HRC only.

Induction heat treatment of a ISO C45 steel bar

Feb 01, 2006 · 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.Whats the hardness of S45C after heat treatment The Max. hardness of S45C can be up to HRC60, but its too brittle, so its meaningless. After quenching, tempering for S45C at 150-250 temperature, the hardness is up to HRC50 above, but the toughness is poor, rarely used in production. The heat treatment process common used for S45C is quenching and tempering g at the temperature of 500 650 degree C, which is called quenching and tempering.
