I have some 12C27 that I want to cut up. This steel is cold rolled and supplied in flat sheets. When you cut the sheets by water jet the steel tends to bend and the resulting strips are thus bent. This is apparently do to the internal stresses holding the sheets flat, being released.... or something feel free to correct me. Nobody likes bent steel. We currently cut this steel along the grain. so length-ways along the strip. While in Japan I was told emphatically that strips and blanks should be cut across the grain. I was told that cutting with the grain always resulted in warpage and whilst cutting across limited you strip size to the sheet width, the result was much better. Now I hear from another Japanese source that the steel should always be cut along the grain as other bad things happen when you cut across the grain. So does it even matter? What is the knifemaking consensus? What are the pros and cons of both options? Do you cut with, or across the grain?
