4Cr9Si2 Martensitic heat resistant steel is inlet valve and the exhaust tappet materials. This paper is based on the constitutive relationship of 4Cr9Si2 Martensitic heat resistant steel obtained by isothermal compression; a finite element model of Cross Wedge Rolling was build up for 4Cr9Si2 Martensitic heat resistant steel. In the model the heat conduction between billet and the die, the

Oct 10, 2014 · Cross wedge rolling (CWR) has many advantages in the production of shafts and rolling while a hollow valve is widely used in engine production. In this study, we use the CWR process to produce a hollow valve made of 4Cr9Si2 steel and present the experimental results. To evaluate the CWR process and deeply understand the deformation characteristics, a 3D finite element model

Jan 29, 2016 · Abstract. The hot deformation behavior of 4Cr9Si2 heat resistant steel was investigated by hot deformation compression tests in the deformation temperature range of 9501180 °C with strain rates of 0.110 s 1.The constitutive equation of 4Cr9Si2 heat resistant steel was established to describe the peak stress as a function of the deformation temperature and strain rate.

Technical Information Heat Treatment One of the ways to determine the hardness of steel is the heat treatment and it is classified to 3 types. Heat Treatment Quenching (Tempering) Normalizing Annealing Quenching (Tempering) Normalizing Annealing After heating to over 727°C, cool rapidly down to 550°C in water or oil.
