1. All material is delivered as spheroidized annealed<br />
condition.<br />
2. After reforging, spheroidizing is to be done before<br />
hardening. Please refer to the standard heat treatment<br />
conditions.<br />
3. Stress relief annealing is to be done to remove stress<br />
caused by cold working such as drawing and rolling and to<br />
soften or reduce distortion caused by subsequent hardening.
