This was quite a help for me to understand quite a bit more about metal. I have only picked out specific areas as the document is so large, there's a wealth of info in this. After seeing the chart on page 50, and talking to my instructor, a light kinda flipped on and I realized the 2nd 2 numbers are the carbon content in steel.
The explaination of how the first 2 digits change depending on the alloy was also helpful.
Yeah, I'm a bit green on metal, and even more reason I appreciate passing this on to the IFI folks.
There's a lot of info in that doc.
