Carburising Astm A-216 WCB

Carburising Astm A-216 WCB

Carburising Astm A-216 WCB

(OP)
Hello,
Has someone attempted do carburize astm A-216 WCB (GS-C25)?
Would it be possible to reach around 58 HRC surface hardness with this steel?
I'm doubtful due to it's carbon content being 0,3%.

Thanks in advance!

RE: Carburising Astm A-216 WCB

My question is why do you want to do this? It is feasible I suppose, but it would render the part wholly unsuitable for its intended application as described in A216. A low alloy grade such as SAE 8620 would be better suited to carburizing.

RE: Carburising Astm A-216 WCB

I agree with ironic metallurgist. WCB grades have Carbon of 0.24-0.30% ,while 8620 would be a better alloy for carburizing.

RE: Carburising Astm A-216 WCB

Generally, carburization is suitable for low carbon steel(0.1%~0.25%). It is reported that there are new carburization techniques for high-C materials, however, what's the meaning here? I don't get it.

Hi guys,
I'm aware that SAE 8620 is better suited. We have a lot of WCB that was used for other project and that is now descontinued, so we want to utilize the remaining steel in other parts. Since the other properties of the WCB go with our project, the carburizing part is the only one we are not so sure due to it's higher carbon content.
I guess my question is if anyone has carburized 0,3% C steel before and got a hardness close to 58 HRC.

"so we want to utilize the remaining steel in other parts."

I am confused. WCB grade is for pressure castings, how do you intend to redeploy such parts by carburising?
