cost of carburising and carbonitriding
cost of carburising and carbonitriding
(OP)
If we disregard the case depth, but to have the case hardness controlled at HV 450 min. and core hardness at HV 270~390 for a part made of low carbon 1018/1022. which of the process will cost less? gas carburising or carbonitriding? and why?
Best regards,

RE: cost of carburising and carbonitriding
You will be hard pressed to get the core hardness you require with either of these materials unless the cross section is less than 1/2". The case hardness will generally be quite higher than you desire on either material
Come back with a little more information as to part's dimensions.
RE: cost of carburising and carbonitriding
If we assume 1 to 1, say the quantity it's big enough to occupy the full capacity of one heat treatment line in one run, how much roughly in percentage will the parts' cost (treated through these two different processes) be different from one another?

A note of caution on carburizing or decarburizing on of fasteners. If the fastener is fatigue application carburization or decarburization of the fastener can greatly reduce the fatigue life of the fastener.
If you need a harder or stronger fastener I would suggest changing the material instead of carburizing or carbonitriding.
