The test results show that the surface of H13 steel can obtain the optimum performance at temperature of completeannealing, quenching and tempering.
试验结果表明H13钢在最佳完全退火温度、淬火温度、回火温度下可得到最优综合性能。
2
Triangular structure of the outer conductive copper wheel points inside and outside two groove, the copper wire inside groove introduced, completeannealing.
三角结构的外层导电铜轮分内外两沟，铜线经内沟引入，完成退火。
3
If the red hot wire directly out of the cooling, the annealing is not complete, steel wire hardness, not easy to spring.
