4140 steel tempering curve Introduction

4140 Tempering Curve - Metal and Metallurgy engineering ...

Sep 11, 2012 · 4140 Tempering Curve 4140 Tempering Curve paras99 (Automotive) (OP) 11 Sep 12 10:18. Hi, does anyone know if there is data available for a hardness vs temperature curve for 4140 steel at a certain time. I have been looking everywhere and cant seem to find it. Your help would be much appreciated. thank you

The ASM Heat Treater's Guide has a hardness vs. tempering temperature chart but my version does not show any time reference. What time are you looking for?Anywhere between 2 and 72 hours will work. Another thing I forgot to mention was that is the 4140 material air cooled instead of quenchedHere you go. it is on page 148 akronsteeltreating/images/ast-book.... As for the time 2 hours at temperature. As for cooling from tempering temperture Air cooled is best. However, if it is not complex geometry or very thin it can be quenched. This won't affect the microstructure but will induce some residual stresses. Design for RELIABILITY, manufacturability, and maintainability2
