Subject: Re: Cast iron to Carbon Steel Author: GRoberts [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 21:16:49 10/18/03 Sat In reply to: unclesyd 's message, "Re: Cast iron to Carbon Steel" on 21:15:23 10/18/03 Sat You need to know what kind of cast steel the coupling is. It could be anything from ASTM A216 WCB or A27 Gr. 60-30, which you could weld without preheat to A148 Gr. 260-210 or A958 Grade SC4340, both of which you would run into problems without preheat. If it is cast ironas musashi's comments pertain to, it is a whole different ballgame. [ Next Thread | Previous Thread | Next Message | Previous Message ]
