Ok well I am hting at 1095 blade. I hted it like i normally do which is bring it to 1525 let it soak for 5 min and quience in salt brine. well this time i pulled it out of the brine and it was curved bad. well I read that you could straiten it during tempering process so I tempered it at 450 for 2 hours.While it was still hot I then clamped it to a straight surfaace with a shim to allow it to bend slightly the opposite direction. well I unclamped it and it was still warped bad. so I decided to redo the whole process. I heated it to 1525 and let it cool in the ht oven. I then heated to 900 and straightened the lade and put it back in thte oven until it reached 1525 and let it cool in the oven again. Now I need to know what my next process would be in order for this not to happen again. I think the reason this happened in the first place and did not for any other was I had to heat the blade during the grinding process in order to give the customer the forged look he wanted. To do this I heated the blade to 1600 pulled it out and hammered on it. I did this 4 times. well I guess I forgot to normalize after that because I never included this in the process before. So If someone can help me with the next steps I would appreciate it.
