What reading level is Hardening And Tempering book?
To quickly assess the difficulty of the text, read a short excerpt:
It illustrates a very practical use of the shield method. The die is split at one point, being of the adjustable type. Inasmuch as only the teeth are hardened, there is no danger of cracking the die in adjustment, and there is less distortion and change of pitch. The cover is made in one piece and can be used several times before being destroyed by the heat.
The third piece shown in Fig. 9 at C is a plain blanking die, but in- stead of being hardened around the edge of the cutting part as at A,... it is hardened half the thickness of the steel, leaving the whole lower half soft, this being protected by the cover, while the upper half is hardened. This gives the die all the advantages of a die made of com- posite steel, a material that is made of half tool steel and half soft steel or iron welded together. This material is extensively used on small die work, but the shield method makes its use unnecessary as all its advantages are obtained very simply, without the risk of split- ting at the weld, as sometimes happens with composite steel.
