4130 dimensional change in heat treatment
There is a definite volumetric change due to crystal structure changes in austenitization and martensite formation, amonng others. I have gotten best estimates of .0005 in/in to .002 in/in as a max. It varies depending on the particular alloy and teh tempering temperature. Thanks- rwilcox

4130 dimensional change in heat treatment
What I am looking for is a general rule of thumb for the volumetric change of 4130 with a standard quench and temper process....- rwilcox

4130 dimensional change in heat treatment
We have a cast 4130 part that we quench and temper to RC 44-48. How much will the material grow or shrink in heat treatment? Is there a reference which tabulates growht and shrinkage of various steels in heat treatment? Thanks- rwilcox
