锻圆厂家力学性能：

①顺零件的主应力方向切取纵向试样:在零件高应力部位切取纵向、横向和高度方向试样

②零件有金属流线要求的部位

③铸造变形里小的部位

④凑近钢锭冒口一端的部位

⑤在锻件截面内，圆形实心件普通在距外貌1/3半径处切取：矩形实心件在距外貌1/6 对角线处切取:空腹件则在1/2壁厚处切取

Forging round manufacturers mechanical properties:

1 Cut the longitudinal specimen along the direction of the principal stress of the part: cut the longitudinal, transverse and height direction specimens at the high stress part of the part

2 parts have metal flow line requirements

3 small parts in the casting deformation

4 close to the end of the steel ingot riser

5 In the forging section, the circular solid part is usually cut at a radius of 1/3 from the outer appearance: the rectangular solid part is cut at the diagonal of 1/6 from the outer appearance: the hollow part is cut at the 1/2 wall thickness
