Just trying to make heads and tails of it all. How do strength, toughness, edge-holding ability and hardness all relate to one another?
As I understand them...
Toughness - resistance to breaking, chipping, etc. - Softer steel = tougher steel - Less Carbon
Strength - usually this is the term to explain edge holding ability. - Harder steel = stronger steel. Usually, this means that the steel contains more carbon - carbon makes steels harder/stronger. This means the steel won't bend or give as much as softer steels.
Hardness - The Rockwell scale measures this and it is determined by how far a diamond tipped instrument can be pushed into the steel under a specific (high)pressure load. The depth of the penetration is measured and a Rockwell hardness number is given to the steel based on that measurement.
Hope this helps. And, If I am incorrect on anything - please don't hesitate to let me know. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
so if this is correct, then how does INFI fair??? its hard.... yet soft... ??? <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />
