Making steels stronger
As we get into modifying a steel's strength and hardness, keep a couple things in mind. First, don't confuse hardness with hardenability. A steel's maximum hardness is a function of its carbon content: more carbon, more hardness. Hardenability, on the other hand, refers to the amount of... Read more...

The structure of metal
As you think about molten metal, keep a couple of points in mind. First, heat flows to cold-always. And that becomes more understandable when you consider that warm atoms are moving faster than cold atoms. And those fast-moving atoms are bumping into other atoms, causing them to move quickly....

Die designs for wide bends
Another design challenge is the thin-material, precision progressive die for achieving consistent bends of more than 90 degrees. These dies have material less than 0.020 inch thick and can achieve a tolerance of ±1 or 2 degrees for an angle on the final part. Any tool in any shop is... Read more...

Know your bending basics—Part I
Editor's Note: This article is Part I of a two-part series discussing bending. Read Part II .
Of all of the operations that typically are done in a stamping die, it seems that achieving and maintaining a 90-degree bend are two of the most difficult.
To accomplish these tasks... Read more...
