.... This appendix discusses the advantages of boost/diffuse carburizing cycles. A table lists typical carburizing constants and boost/diffusion ratios needed to obtain a 0.80 to 0.90% surface carbon content in a low-alloy, low-carbon steel. A figure illustrates possible carbon penetration profiles from boost...
