Hey all,
At our manufacturing plant we are experiencing about 20% of our tools cracking along a groove on the shank (picture below) of one of our tools. Our current process is to heat the 1045 steel tools to 1500F for 45 mins, then take them out and slowly enter them into the brine quench groove side first. The brine is at 10 brix and has an agitator. This process has been done for years and only now are the tools beginning to crack. The tools are then drawn at 500F for an hour and a half.
We have another tool that has the same shank geometry and we use the same process, and have never had any cracking.
Open to any ideas and suggestions on how to stop the cracking! Have tried many different ways of quenching but nothing is working.
